 Before compiling the code, create file loraconf.h in the /src directory from the template [loraconf.sample.h](https://github.com/cyberman54/ESP32-Paxcounter/blob/master/src/loraconf.sample.h) and populate it with your personal APPEUI und APPKEY for the LoRaWAN network. Only OTAA join is supported, not ABP. The DEVEUI will be derived from the device's MAC adress during device startup and is shown as well on the device's display (if it has one) as on the serial console for copying it to your LoRaWAN network server settings. If you enter a DEVEUI in loraconf.h it will be used instead.

 # Uploading
 
 To upload the code to your ESP32 board this needs to be switched from run to bootloader mode. Boards with USB bridge like Heltec and TTGO usually have an onboard logic which allows soft switching by the upload tool. In PlatformIO this happenes automatically.<p>
