Depending on board hardware following features are supported:
- LoRaWAN communication, supporting various payload formats (see enclosed .js converters)
- MQTT communication via TCP/IP and Ethernet interface (note: payload transmitted over MQTT will be base64 encoded)
- SPI serial communication to a local host
- LED (shows power & status)
- OLED Display (shows detailed status)
- RGB LED (shows colorized status)

# Time sync
Paxcounter can keep it's time-of-day synced with an external time source. Set *#define TIME_SYNC_INTERVAL* in paxcounter.conf to enable time sync. Supported external time sources are GPS, LORAWAN network time and LORAWAN application timeserver time. An on board DS3231 RTC is kept sycned as fallback time source. Time accuracy depends on board's time base which generates the pulse per second. Supported are GPS PPS, SQW output of RTC, and internal ESP32 hardware timer. Time base is selected by #defines in the board's hal file, see example in [**generic.h**](src/hal/generic.h). Bonus: If your LORAWAN network does not support network time, you can run a Node-Red timeserver application using the enclosed [**Timeserver code**](/src/Timeserver/Nodered-Timeserver.json). Configure MQTT nodes in Node-Red to the same LORAWAN application as paxocunter device is using.

The device listenes for remote control commands on LoRaWAN Port 2. Multiple commands per downlink are possible by concatenating them, but must not exceed a maximum of 10 bytes per downlink.
Note: all settings are stored in NVRAM and will be reloaded when device starts.
Note: settings can be stored in NVRAM to make them persistant (reloaded during device startup / restart). To store settings, use command 0x20.
Send for example `8386` as Downlink on Port 2 to get battery status and time/date from the device.
