TTGO T-Beam TTNMapper Sketch

A Firmware for the TTGO T-Beam and Heltec Wireless Stick to use it as a standalone TTNMapper (-> https://ttnmapper.org) Based on the Ardino Sketch at https://github.com/Bjoerns-TB/Lora-TTNMapper-T-Beam

• Converted to PlatformIO
• Use Second ESP32-Core for UI Thread (better button responsivness)
• Always show Satellites in view / in use
• Support button to switch through different send intervals

The Code needs the following Libraries (they are configured as dependencies in platformio.ini):

• LMIC-Arduino
• SimpleButton
• TinyGPSPlus
• U8g2

Please Insert your Network / Application Keys and Device ID from the TTN-Console into include/config.h before flashing, it will not work without. An example of config.h you find in /include/config.sample

The platformio.ini configures the Pins for all 3 boards depending on the ENV of your choice

For Heltec Wireless Stick (no integrated GPS) you have to solder the GPS to Pins RX 23 and TX 17. The 64x32 OLED is very limited to visualize things. The onboard LED is on as long a TTN packet is queued
