# ATTNode v3 Firmware (WiP)
|
|

## Disclaimer

|
THIS IS STILL WORK IN PROGRESS!
|
|
|
|
## Configuration and Programming
|
|
|
|
This is the Work in Progress Repository for ATTNode v3 compatible firmware. At the moment it supports LoRa communication using OTAA and a BME280 or SHT21 sensor, as well as deep sleep between measurements.
|
|
|
|
As there is no PlatformIO Support for the ATTiny3216 yet, it is (for now) developed using Arduino IDE and the [MegaTinyCore](https://github.com/SpenceKonde/megaTinyCore). You also need to set the correct Settings for programming the ATTiny3216 in ArduionIDE. Here is a screenshot of the settings I use:

|
You also need to install the MCCI Arduino LMIC Library form the IDEs Library Manager or from https://github.com/mcci-catena/arduino-lmic
|
|
|
|
Before Compiling and Flashing make sure to copy config.h.example to config.h and set your LoRa OTAA Keys there. You can also set the Sending Interval and used Sensors there.
|
|
|
|
Programming is done using a [MicroUPDI Programmer](https://github.com/MCUdude/microUPDI) - for other pogramming variants see the MegaTinyCore documentation.

## Configuring via Downlink
|
|
|
|
It is possible to change the sending interval via Downlink-Packets at runtime. The time between Transmits is specified in minutes (or more exactly, 64 Second intervals) and has to be sent as a 2 byte value, which will be interpreted as an uint. so for example 0x0001 means 1 Minute, 0x0002 means 2 Minutes and so on. Sending 0xFFFF resets the value to the compiled in default.
