# Preparing
Use <A HREF="https://platformio.org/">PlatformIO</A> with your preferred IDE for development and building this code.
Before compiling the code,
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.
- **edit paxcounter.conf** and taylor settings in this file according to your needs and use case. Please take care of the duty cycle regulations of the LoRaWAN network you're going to use.
- **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.
@ -60,6 +62,10 @@ If your device has a fixed DEVEUI enter this in your local loraconf.h file. Duri
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.
# Building
Use <A HREF="https://platformio.org/">PlatformIO</A> with your preferred IDE for development and building this code.
# 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>
