 by uncommenting <b>// #define SHOW_RX_PACKET</b> the tracker shows received LoRa APRS packets in raw format for the time in milliseconds defined in SHOW_RX_TIME - both in ...config.h<br>

 <b>new features:</b><br>
+- Trackermode setable via config file
+- BME280 sensor implemented (Temp und Hum only)
 - compressed packets in tracker mode
 - symbol RV added
 - show RX packets
