Release 4.0

This release should work with T-TWR 2.0 and T-TWR 2.1 as well as Arctic Tracker hardware (v4 and v4-UHF/LoRa). Attached zip files with pre-built bits and pieces can be used for flashing with esptool or the Windows flashing tool. In this release several fixes and updates have been done. Most notably:

• AFSK decoding of APRS frames should now work reasonably well. It should work without needing the squelch signal. TX use the RSSI command to determine if the channel is free.
• A LoRa APRS version of the hardware is fully supported.
• Digipeating and igating should work. Track logging (with Polaric Server) should work now.
• Various fixes. Radio and tracking is on by default.

I am working with more documentation.

Release 3.3

This release should work with T-TWR 2.0 for which there is a zip file with pre-built bits and pieces that can be used for flashing with esptool or the Windows flashing tool. Several fixes and updates have been done for example:

• Timezone support. Get time from GNSS.
• GUI and display updates. Use larger fonts for some items, show time, show RX signal level...
• Commands, remove some, add some.. Add command for setting low power.
• AFSK demodulator work
• Webapp updates
• Other minor fixes..

The AFSK demodulator uses the ADC properly (continous mode), it can do without the squelch signal or with setting squelch to 0 though it is still somewhat work in progress. T-TWR 2.1 is work in progress. Most of it should work though the ADC setup may need adjustments..

Release 3.2 (works in T-TWR)

From this release we provide a zip with files used for flashing with esptool or the Windows flashing tool.
Other changes:

• Move to IDF 5.1.3
• Use FATFS instead of SPIFFS.
• Automatic setting of firmware date
• Use menuconfig to select target device
• Move radio drivers to separate component
• Some other minor fixes.

Release 3.1 (works on T-TWR)

I am pleased to present a release of Arctic Tracker port for the LilyGo T-TWR-plus 2.0. See the readme and the HamLabs posting.

Some small fixes are made and menu (display) is somewhat improved since the pre-release.

Release candidate 2 (works on T-TWR)

Some fixes to wifi, and the webapp, etc..

Release candidate (works on T-TWR)

Release candidate for testing. It should work for the LilyGo T-TWR-plus 2.0. It is based on ESP-IDF 5.0.6. A compiled binary is available here and on https://arctictracker.no. It can be flashed by setting the device in download mode and using esptool.py.

I hope to be able to create a image that is compatible with the UF2 downloader as well. Any tips or on how to do this is appreciated. I also intend to add more documentation and a new post on hamlabs.no.

Update: It is possible to convert to UF2. For example by using uf2conv.
