This is a LoRa APRS Tracker with Access Point for real time configuration. Its main use is to send a periodic beacon containing:
- callsign
- GPS or fixed coordinates
- Altitude
- Battery voltage and current
Any received LoRa APRS packet, including the one repeated by a local digipeater, is displayed in the (very) small display.
This LoRa APRS Tracker is derived from (https://github.com/lora-aprs/LoRa_APRS_Tracker) by peterus
I added an Access Point and Captive Portal for easy configuration.
You can use one of the Lora32 boards:
-
TTGO T-Beam V0.7 (433MHz SX1278) The original software is designed for it, also, but I never tried.
-
TTGO T-Beam V1 (433MHz SX1278) This boards cost around 35 Euros and includes a small 0.96" display Keep in mind: you need a 433MHz version!
-
Or you can build your own. See below
Please note that I changed the GPS antenna with a most performing one.

The best success is to use PlatformIO (and it is the only platform where I can support you).
- Go to PlatformIO download and install the IDE.
- If installed open the IDE, go to the left side and click on 'extensions' then search for 'PatformIO' and install.
- When installed click 'the ant head' on the left and choose import the project on the right.
- Just open the folder and you can compile the Firmware.
- Press the service button (the middle one) for more than 5 seconds and a WiFi hotspot will be alive (SSID: ESP32_APRS)
- Connect to it with your smartphone or PC using the password 12345678
- After connection navigate to http://192.168.4.1 and the settings web page will show
Be very careful when you change them!
activate only one!!!
- I suggest to start with fixed_beacon (that don't use GPS and send the location set)
- Then try beacon (use GPS location).
- Finally you can try smart_beacon in a moving vehicle.
