Hold the button for 30 seconds to perform a full factory reset. In this case all configuration profiles will be cleared. All entered device UIDs will be saved in your web browser's local storage so you don't have to enter them again. You can also add the SharkRF Link application to your phone's home screen by clicking on the Add to Home Screen button at the bottom of the page on your mobile phone's browser. Page 36 Opening the web interface If you are using an iPhone and the Add to Home Screen button does not appear at the bottom of the SharkRF Link page, you can use the following method to add the app icon to your home screen: Open SharkRF Link in the browser Click on the iPhone's Share icon at the bottom Click on the Add to Home Screen button You can see the whole process on this animation: Other ways to open the web interface A recommended app for Android is Fing Network Tools.
Some Wi-Fi access points and routers have multicast data disabled by default. The device's IP address is displayed by hovering the mouse above the hostname. The hostname will be hidden on small displays mobile phones. In this case, you can get the current IP address on the Network page, Network settings section.
You can also see the device's IP address on the Network page, Current configuration section. When the web interface is communicating with the openSPOT2, a loader animation 2 pulsating circles is displayed next to the hostname at the right of the header. The currently active configuration profile number and name is displayed at the left of the footer. You can also switch between configuration profiles there.
Please read the Notes on configuration profiles section for more information about configuration profile switching. The openSPOT2's status is displayed at the middle of the footer. The Advanced mode checkbox is at the right of the footer. If this is checked, all advanced mode settings show up. Advanced mode is not needed for normal operation. Call log The call log displays all calls coming from the network, from the modem, or from the openSPOT2 itself voice announcements.
In modes where IDs are used as destination and source IDs ex. You can get more information about an ID or callsign if you hover the mouse over it. Each call log entry has information about the call at the top right corner of the entry bubble. BER is displayed in percent after the letter B, packet loss in case of network calls is displayed in percent after the letter L.
The call duration is also displayed after a call ends. You can export all call log entries in CSV format by clicking on the Export call log button. If the Limit call log lines is checked it's checked by default then only a limited number of call log entries are allowed to be in the call log. The device log is only shown if Advanced mode is enabled.
All log lines are shown here except lines coming from the Wi-Fi module handler. Use the USB serial console log if you also want to see these messages. If Limit lines is checked it's checked by default then only a limited number of log lines are allowed to be in the log.
You can export the log lines to a. The USB serial console can only be used if this field shows connected. The supplied USB cable supports data transfer. BER is calculated also for packets received from the network, not just from the modem. The dejitter queue graph only shown if Advanced mode is enabled shows the number of packets waiting in the dejitter queue. About the dejitter queue All packets received from the network will first go to this queue to eliminate network jitter. If the dejitter queue length is too short, the graph's line can touch zero during a call and the audio can stop for a moment as the modem runs out of frames to transmit.
If the queue's length is too long, the delay can be uncomfortably high. You can use this graph to set a proper dejitter queue length. There should be at least a few packets in the dejitter queue when receiving a call from the network. You can set the dejitter queue length on the Network page the setting only shows up if Advanced mode is enabled. The easiest way to choose which connector to select is using the Quick Setup.
You can activate a connector by selecting it from the Edit connector list and clicking on the Switch to selected button. You can edit a connector's settings by selecting it from the Edit connector list. Don't forget to click on the Save button after changing a connector's settings.
These frequencies and modem modes will be used when the connector becomes activated. Some connectors have Add server and Remove buttons. These can be used to add and remove custom servers in the server list. Note that these custom servers are stored in the browser's local storage they won't show up using another browser.
Some connectors have a Keepalive interval setting. This means the server requires the openSPOT2 to periodically send keepalive messages to the server. The RX timeout setting specifies the time after the last received valid network packet needed for the openSPOT2 to consider the connection is dead and it should reconnect.
The Connect retry interval sets the delay between server connect retries. As a general rule, try to use a server nearest to your location to avoid packet loss and high latency. Please see the Connectors section for more information about each connector. General connector settings This section is only available if Advanced mode is enabled. Page 43 Connectors page By setting the Change to Null connector after last call other than 0 will change the active connector to the Null connector after the last received call minimum timeout value is 5 minutes.
For example, if you set a timeout of seconds, openSPOT2 will change to the Null connector if there is no call received in the last 10 minutes. If you change the modem mode, RX or TX frequency on this page, the values will be copied to the currently active connector's settings.
If the Idle modem mode is activated then the openSPOT2's modem won't transmit and will ignore all received transmissions. Frequency The Modem receive frequency offset setting can be used to correct the frequency difference RX offset between the openSPOT2 and the used transmitter. This setting is only available if Advanced mode is enabled.
Setting an RX offset may be needed in case others report that transmissions coming from your transceiver have voice quality issues. This should rarely happen as the openSPOT2 has a built-in, factory calibrated, extreme accurate clock reference. You can also use the AutoCal special connector to find out the required RX offset value, or you can use the openSPOT2's built-in local echo service to find out the RX offset value yourself by listening back your recorded voice.
Other modem settings If Advanced mode is enabled, you can tweak various other modem parameters at the bottom of the modem page. The Call hang time setting specifies how many milliseconds the openSPOT2 will wait after the last valid frame has been received to consider a call has been finished with a timeout. The Ignore RX after TX setting specifies a time for which all received frames by the modem will be ignored after the last TX has ended.
This is useful if you want to use the openSPOT2 to link a repeater to the internet through RF and the repeater has a lengthy internal buffer and it is still transmitting even after the openSPOT2 has finished transmitting which means the openSPOT2 will start receiving it's own stream again.
Page 46 Modem page The modem's Sensitivity level can be changed in 6 levels. Note that increasing sensitivity decreases the linearity of the filters, which may result in incorrectly demodulated bits which means increased BER. By default, sensitivity is low level set to 5 or 6 for modem modes using 4FSK.
The sensitivity of the modem's filter can be changed with the Filter gain setting. By default, filter gain is set to 8. These values will be considered as low and high thresholds for the Auto AGC circuitry in the modem. You can also reset all modem settings back to defaults by clicking on the Reset modem config back to defaults button. All of the settings above are stored independently for each modem mode in the current profile. Configuration profile You can use 5 different configuration profile slots.
You can switch between them on the web interface, or by using your radio see the Control calls section for more information. By setting the Change after last call setting to non-zero this setting is available if Advanced mode is enabled , the openSPOT2 will switch to the specified profile slot after a timeout since the last call was received. The Don't show init setup on login checkbox is checked if the Initialization setup has been completed.
Notes on configuration profiles Please keep in mind that all configuration profiles are empty by default, so if you switch to a previously The openSPOT2 reboots on profile switch. Wi-Fi networks and passwords are stored for each profile separately. The web interface password is stored for each profile separately. Firmware upgrade The openSPOT2 will automatically check for firmware and data upgrades periodically, as specified by the Check interval setting only available if Advanced mode is enabled.
Data upgrades are applied immediately, but upgrading the firmware requires a reboot to the bootloader. If a new firmware has been downloaded, a reboot will be automatically scheduled for the local time set by the Auto upgrade at setting. By default it's set to 4am next day. Currently only developers and alpha testers have access to the network's features.
Eventually, these features will be available for all openSPOT2 users. Some announcements are played locally from the openSPOT2's built-in flash memory, but some are played using our open source voice announcement server. Page Location Settings Settings page group list. If you enable Advanced mode, the following settings will show up: You can shorten profile announcements by checking the Shortened profile announcement checkbox.
You can disable built-in voice announcements by checking the Use server only checkbox. You can set your own voice announcement server's host and port. Net state announcement int. Location settings Setting location data is optional. Latitude and longitude is in decimal degrees. Google Maps will display a location's coordinates in decimal degrees if you click on it: Both height values refer to the height of your openSPOT2 they are used separately.
If Advanced mode is enabled, the following settings show up: If a call is received by the modem to the Echo ID, then the openSPOT2's built-in local echo service gets activated. It will record the call and plays it back after the call is finished. Both private and group calls are answered with a private echo call reply. If the Allow only IDs as cross mode callsigns setting is enabled, and the source callsign of a cross mode call has no associated ID in the database, and also it can't be parsed into a DMR ID, then the call will be ignored.
If the Send no in-band data to network setting is enabled, then in-band data coming from the modem like the talker alias or in-band GPS position information won't be sent to the network. If the Force talker alias to DMR network is set, then this talker alias will be sent for all calls coming from the modem. If the Send no in-band data to modem setting is enabled, then the openSPOT2 will remove all in-band data from calls coming from the network.
By default this setting is enabled. If you have a radio which supports talker alias decoding like Hyteras with at least firmware version v8 , turn off this setting to let the openSPOT2 pass through in-band data to your radio. If you have a radio which does not support talker alias decoding, turn on this setting to prevent issues with decoding voice calls containing in-band data voice stuttering, calls dropping etc. If a call is received by the modem to the Echo callsign, then the openSPOT2's built-in local echo service gets activated.
Allow data calls to network: if enabled, data calls will be forwarded from the modem to the network. This is not required for normal operation. Ignore Wires-X button commands: Wires-X button commands received by the modem will be ignored in case this settings is enabled.
These automatic messages can be disabled with this setting. Hide profiles in Wires-X "all" reply: if this setting is enabled, configuration profiles won't be listed on the first page for a Wires-X "all" server search. See more info at each connector's Page Nxdn Settings Settings page description, or at the Control calls section.
Cross mode group call DTMF code: if a connector is active which supports group calls and C4FM cross mode, then this code can be used to start group calls to the ID entered after this code. Default callsign for cross mode calls: this callsign will be used on C4FM networks for calls coming from a radio which does not have a callsign ex.
Note that if the incoming call's talker alias is decoded, then it will be used instead of this default callsign setting. If a call is coming from a mode which does not have ID information ex. If the Allow only IDs as cross mode callsigns setting is enabled, and the source callsign of a cross mode call has no associated ID in the database, and also it can't be parsed into an NXDN ID, then the call will be ignored.
P25 settings Each timeslot is 6. Lock settings This section is only available if Advanced mode is enabled. There are also some buttons for reboot and config profile reset actions. The Network status section shows current network status. The Internet connection quality is determined by the openSPOT2 by periodically measuring the network latency.
You can get the measured latency value by hovering the mouse above the quality display circle. The Wireless regulatory domain is set by the country of operation. This is the same as pressing the button for 3 seconds. Network traffic Page Network Settings Network page The traffic graph can be shown by clicking on the arrow at the top of the Traffic section.
The openSPOT2 uses very little internet traffic. You can set a password by entering it in the Change web int. To reset the original behavior and clear the password, click on the Clear password button. The hostname is also displayed at the top right corner of the web interface.
If you have multiple openSPOT2s on the same network, make sure you use different hostnames for each of them. The following settings are only available if Advanced mode is enabled. Please see the About the dejitter queue section of the user manual for more information on the Dejitter queue length setting. The openSPOT2 checks for internet connection availability and quality periodically.
The interval of these checks is set by the Internet conn. Check the Send log to syslog server checkbox to enable using the syslog server. Please see the Powersaving section of the user manual for more information about the Power saving feature.
NTP settings This section is only available if Advanced mode is enabled. After that, the browser is updating the displayed clock and if the browser, or the web interface's browser tab is sent to the background then the time will be updated more irregularly due to the browser's CPU power saving mechanism.
Reload the web interface to make the displayed time accurate again. Wireless settings Page 58 Network page If Advanced mode is enabled, you can define up to 5 Wi-Fi networks per configuration profile to connect. If it's not available either, then it'll try the third one and so on.
After trying connecting to all of the configured networks, it restarts the sequence with the first network. If you are manually adding a connection to an iPhone's shared internet connection then make sure you copy and paste the phone's Wi-Fi SSID as the iPhone uses a special apostrophe character which looks nearly the same as the one you can enter with your keyboard, but it's different, and all characters need to match.
If the Save to all configuration profiles is active then the configured Wi-Fi networks will be saved to all profiles and will be common between profiles. WEP encryption is also supported if the network key length is 5 or 13 characters. IP settings This section is only available if Advanced mode is enabled. This is only recommended for advanced users. If the openSPOT2 can't connect to a server for ex. MAC settings This section is only available if Advanced mode is enabled.
This is useful if you try to use a Wi-Fi network which uses a captive portal for authentication example: hotel or airport networks. Switch the openSPOT2 back to normal mode by holding the button for 3 seconds, or by clicking the Switch wireless mode button at the top of the Network page. Please keep in mind that MAC cloning may cause packet loss and the network connection of both devices may get periodically interrupted.
On small screens they are hidden, and their contents can be found on the Tools page. Quick call Reflector and talkgroup linking and unlinking is done by the network, not the openSPOT2. These empty calls will also show up on the BrandMeister Network's dashboard. Starting a short private call to a reflector ID between and will link the reflector. Starting a short group call to a talkgroup ID will link that TG. On the BrandMeister network, reflectors are unlinked by starting a private call to ID , and both reflectors and talkgroups are unlinked by starting a group call to ID Quick call shortcuts can be stored in the openSPOT2's current configuration profile.
If you hover the mouse cursor over a saved talkgroup's button, or the button is pressed for a few seconds then the BrandMeister talkgroup's name will appear. If the Auto group call before shortcut call checkbox is checked, then the openSPOT2 will automatically start a quick call to TG to unlink everything before quick calling the desired ID. BrandMeister Manager The API key's validity can be checked by clicking on the Check key button.
Sent messages are displayed on the right, received messages are displayed on the left of the chat box. You can click on each message for additional information. The modem radio button is disabled if the modem is not in DMR mode.
Note that the openSPOT2 only stores the last received message, so you have to keep open this page in your browser to receive more than one message at once. Note that the network must know about the location of your Source ID.
Queued unsent messages are displayed with a blue background, sent messages are gray. Note that the displayed current timeslot number and time is calculated by the browser and is not equal to the openSPOT2's internal device time and timeslot framing which is more precise. If the Send to radio button is set to Modem then you can directly add messages to the queue which will be transmitted by the openSPOT2.
Multiple destination callsigns and transmitter groups can also be specified in a comma separated list. This feature is available when the APRS connector is enabled. The openSPOT2 stores the last 10 messages in it's internal memory, so you can receive messages even if the web interface is not open. You'll get a notification about unread messages if you open the web interface. If you reboot the device then all stored messages will be lost.
Confirmed messages need to be acknowledged by the recipient. If the recipient is unavailable which means no acknowledge is received for a specific time , then the openSPOT2 retries sending a few times before the message send times out. You can cancel the confirmed message send by clicking on the Cancel button. If a message bubble is clicked then it's callsign will be set as the message send destination callsign. ID database lookup If the Auto match ID and callsign fields checkbox is checked, then all callsigns and IDs will be matched when saving connector settings, and a warning will be displayed if the entered callsign does not match the entered ID according to the database.
This is to prevent typos or invalid IDs when trying to connect to a network, as most servers do not allow connections with invalid IDs or callsigns. You can also request an immediate upgrade availability check, and manually start the upgrade process if auto upgrades are disabled on the Settings page, Firmware upgrade section. Page Login Page Login page Login page This is the page where you can log in to the web interface.
The openSPOT2 does not have a web interface password by default, so the login page is not displayed initially. You can set a login password on the Network page, Network settings section. If you check the Remember me checkbox, the openSPOT2 will not ask for a login password until the device gets rebooted, or the browser forgets the login cookie. Page Null Null Null connector The Null connector is a special connector - as it's name says - it does not connect anywhere.
This is the default active connector when the openSPOT2 is unconfigured. The easiest way is to use the Quick setup to connect to these networks. The default server password for BrandMeister servers is passw0rd or password, but some servers do not use these defaults. In this case take a look at the BrandMeister wiki, or ask the server's admin for the password if the openSPOT2 won't connect with the default one.
If you can't connect to a BrandMeister server because the authentication has failed, then turn off Hotspot Security on your BrandMeister SelfCare page, or use the hotspot password you've set there as the server password. If you are using a BrandMeister server in Homebrew protocol mode, you can see the list of currently linked static, dynamic talkgroups and reflectors on the openSPOT2's Status page.
In cross modem modes, you can set the Route cross mode calls to ID to the talkgroup ID you want to talk to set the call type to Group call. Page 72 C4FM notes If you use a C4FM radio, make sure it is in digital narrow DN mode, otherwise your calls can't be converted and only silence will be sent to the network. Advanced settings If Advanced mode is enabled, the following settings become available: You can set a backup server which will be used if the openSPOT2 can't connect to the primary server for Backup server activate connect timeout seconds.
If the backup server is disconnected then the primary one will be tried automatically again. This setting specifies which TDMA channel is used for sending calls to the server. On the BrandMeister network the DMO mode links the two timeslots together, so this setting is irrelevant.
Please see the Quick call's description for more information about this feature. Using the auto connect feature is not needed and not recommended on BrandMeister, as this network supports auto static talkgroups: the first talkgroup you call after calling TG will be set as auto static. Auto static talkgroups will not be unlinked after a timeout like dynamic talkgroups this timeout is usually 15 minutes, but this depends on server settings.
Example: start a short call to TG Then start a short call to TG Now TG will be auto static, which means it won't be unlinked after a timeout. This is useful if you only want to use a talkgroup, but the server always links you to a reflector automatically. Note that reflector and talkgroup linking and unlinking is done by the network, not the openSPOT2. These empty calls will also show up on the BrandMeister network's dashboard. You can change the used reflector ID by starting a short private call on your radio to the desired reflector ID between and If you use a C4FM radio, make sure it is in digital narrow DN mode, otherwise your calls can't be converted and only silence will be sent to the network.
You can switch to gateways the same way. Switching to XLX servers D1C D D In this case, set the local module to a space character in the openSPOT2. N6NLX , Nov 13, KN4HGV likes this. I use the Raspberry Pi a lot, there are 3 around the shack, but I dislike the microSD corruptions and required re-images.
This is why I would not consider a ZumSpot. The reason for this post. Last edited: Nov 13, VA3VF , Nov 13, KA4RUR likes this. Pascal, another great video. I enjoy watching your reviews, you do a great job. K0SZ , Nov 13, That is, as long as you have a network or are able to tether to a cellphone. Just download the Blue DV app and some minor config and you are ready to go. Thanks for reviewing the OS2. Great video pascal and i will be ordering 1 as soon as i already have the little blue openspot 1 and i have never had any problems with it at all,i am sure i will be able to say the same for the new openspot 2.
Thanks again for the video pascal. M0DPX , Nov 13, Not nearly as capable as my Zumspot ant over twice the price!! I honestly don't get it. Seems like a huge profit margin for the manufacturer if folks buy the "unbiased reviews". KC1TV , Nov 14, To each his own. If price is the only consideration, then there are tones of options out there--even a few that are a good bit cheaper than a Zumspot setup. If you lump size, shape, complexity of setup, and complexity of maintenance into function and capability, then the OpenSpot2 is quite a bit ahead.
Just determine what you value most, and make your choice. W4EAE , Nov 14, The JumboSpot is the lowest priced alternative currently, I think.
