# pico-lorawan
Enable LoRaWAN communications on your [Raspberry Pi Pico](https://www.raspberrypi.org/products/raspberry-pi-pico/) or any RP2040 based board using a [Semtech SX1276 radio module](https://www.semtech.com/apps/product.php?pn=SX1276).
Based on the Semtech's [LoRaWAN end-device stack implementation and example projects](https://github.com/Lora-net/LoRaMac-node).
## Hardware
* RP2040 board
* [Raspberry Pi Pico](https://www.raspberrypi.org/products/raspberry-pi-pico/)
* [Adafruit Feather RP2040](https://www.adafruit.com/product/4884)
* Semtech SX1276 board
* [Adafruit RFM95W LoRa Radio Transceiver Breakout - 868 or 915 MHz - RadioFruit](https://www.adafruit.com/product/3072)
* [Adafruit LoRa Radio FeatherWing - RFM95W 900 MHz - RadioFruit](https://www.adafruit.com/product/3231)
### Default Pinout
| Raspberry Pi Pico / RP2040 | Semtech SX1276 |
| ----------------- | -------------- |
| 3.3V | VCC |
| GND | GND |
| GPIO 18 | SCK |
| GPIO 19 | MOSI |
| GPIO 16 | MISO |
| GPIO 7 | DIO0 / G0 |
| GPIO 8 | NSS / CS |
| GPIO 9 | RESET |
| GPIO 10 | DIO1 / G1 |
GPIO pins are configurable in examples or API.
## Examples
See [examples](examples/) folder.
There is a `config.h` file to your ABP or OTAA node configuration for each example.
## Cloning
```sh
git clone --recurse-submodules https://github.com/sandeepmistry/pico-lorawan.git
```
## Building
1. [Set up the Pico C/C++ SDK](https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf)
2. Set `PICO_SDK_PATH`
```sh
export PICO_SDK_PATH=/path/to/pico-sdk
```
3. Create `build` dir, run `cmake` and `make`:
```
mkdir build
cd build
cmake .. -DPICO_BOARD=pico
make
```
4. Copy example `.uf2` to Pico when in BOOT mode.
## Erasing Non-volatile Memory (NVM)
This library uses the last page of flash as non-volatile memory (NVM) storage.
You can erase it using the [`erase_nvm` example](examples/nvm), when:
* Changing the devices configuration
* If your board is timing out with joining the network
