# Preparing
|
||||
|
||||
Before compiling the code,
|
||||
Compile time configuration is spread across several files. Before compiling the code, edit or create the following files:
|
||||
|
||||
- **edit platformio.ini** and select desired hardware target in section boards. To add a new board, create an appropriate hardware abstraction layer file in hal subdirectory, and add a pointer to this file in sections boards.
|
||||
## platformio.ini
|
||||
Edit `platformio.ini` and select desired hardware target in section boards. To add a new board, create an appropriate hardware abstraction layer file in hal subdirectory, and add a pointer to this file in sections boards.
|
||||
|
||||
- **edit src/paxcounter.conf** and tailor 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.
|
||||
## src/paxcounter.conf
|
||||
Edit `src/paxcounter.conf` and tailor 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.
|
||||
|
||||
- **edit src/lmic_config.h** and tailor settings in this file according to your country and device hardware. Please take care of national regulations when selecting the frequency band for LoRaWAN.
|
||||
If your device has a **real time clock** it can be updated bei either LoRaWAN network or GPS time, according to settings *TIME_SYNC_INTERVAL* and *TIME_SYNC_LORAWAN* in `paxcounter.conf`.
|
||||
|
||||
- **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.
|
||||
## src/lmic_config.h
|
||||
Edit `src/lmic_config.h` and tailor settings in this file according to your country and device hardware. Please take care of national regulations when selecting the frequency band for LoRaWAN.
|
||||
|
||||
- **create file ota.conf in your local /src directory** using the template [ota.sample.conf](https://github.com/cyberman54/ESP32-Paxcounter/blob/master/src/ota.sample.conf) and enter your WIFI network&key. These settings are used for downloading updates. If you want to push own OTA updates you need a <A HREF="https://bintray.com/JFrog">Bintray account</A>. Enter your Bintray user account data in ota.conf. If you don't need wireless firmware updates just rename ota.sample.conf to ota.conf.
|
||||
## src/loraconf.h
|
||||
Create file `src/loraconf.h` using the template [src/loraconf.sample.h](https://github.com/cyberman54/ESP32-Paxcounter/blob/master/src/loraconf.sample.h) and modify it, to use your personal values.
|
||||
To join the network and activate your paxcounter, you have to configure either the preferred OTAA method or the ABP method. You should use OTAA, whenever possible. To understand the differences of the two methods, [this article](https://www.thethingsnetwork.org/docs/devices/registration.html) may be useful.
|
||||
|
||||
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 on the device's display (if it has one). It is also printed on the serial console for copying it, if you set *verbose 1* in paxcounter.conf and *debug_level 3* in platformio.ini.
|
||||
To configure OTAA, leave `#define LORA_ABP` deactivated (commented). To use ABP, activate (uncomment) `#define LORA_ABP` in the file `src/loraconf.h`.
|
||||
The file `src/loraconf.h.sample` contains more information about the values to provide.
|
||||
|
||||
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.
|
||||
|
||||
If your device has a **real time clock** it can be updated bei either LoRaWAN network or GPS time, according to settings *TIME_SYNC_INTERVAL* and *TIME_SYNC_LORAWAN* in paxcounter.conf.
|
||||
## src/ota.conf
|
||||
Create file `src/ota.conf` using the template [src/ota.sample.conf](https://github.com/cyberman54/ESP32-Paxcounter/blob/master/src/ota.sample.conf) and enter your WIFI network&key. These settings are used for downloading updates. If you want to push own OTA updates you need a <A HREF="https://bintray.com/JFrog">Bintray account</A>. Enter your Bintray user account data in ota.conf. If you don't need wireless firmware updates just rename ota.sample.conf to ota.conf.

You can add up to 3 user defined sensors. Insert sensor's payload scheme in [*sensor.cpp*](src/sensor.cpp). Bosch BMP180 / BME280 / BME680 environment sensors are supported. Enable flag *lib_deps_sensors* for your board in [*platformio.ini*](src/platformio.ini) and configure BME in board's hal file before build. If you need Bosch's proprietary BSEC libraray (e.g. to get indoor air quality value from BME680) further enable *build_flags_sensors*, which comes on the price of reduced RAM and increased build size. RTC DS3231, generic serial NMEA GPS, I2C LoPy GPS are supported, and to be configured in board's hal file. See [*generic.h*](src/hal/generic.h) for all options and for proper configuration of BME280/BME680.
