Use <A HREF="https://platformio.org/">PlatformIO</A> with your preferred IDE for development and building this code.
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.
Before compiling the code, **create file loraconf.h in your local /src directory** using 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. If you're using popular <A HREF="https://thethingsnetwork.org">TheThingsNetwork</A> you can copy&paste the keys from TTN console or output of ttnctl.
To join the network only method OTAA is supported, not ABP. The DEVEUI for OTAA 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 your device has a fixed DEVEUI enter this in your local loraconf.h file. During compile time this DEVEUI will be grabbed from loraconf.h and inserted in the code.
If your device has silicon **Unique ID** which is stored in serial EEPROM Microchip 24AA02E64 you don't need to change anything. The Unique ID will be read during startup and DEVEUI will be generated from it, overriding settings in loraconf.h.

Description of the RGB LED color (LoPy/LoPy4 and Lolin32 only):
- Yellow quick blink: joining LoRaWAN network in progress or pending
- Blue blink: LoRaWAN data transmit (including waiting for receive windows) in progress or pending
- Green each blink: seen a new Wifi device

* Scan duration sets how long scanning should be going on, interrupting a wifi scan cycle.
* Scan window sets how much of the interval should be occupied by scanning.
* Scan interval is how long scanning should be done on each channel. BLE uses 3 channels for advertising.
* -> Adjust these values with power consumption in mind if power is limited.
