This example application runs out of the box on the STM32 LoRa Discovery Kit (B-L072Z-LRWAN1).
To build and flash the example, you need to have
rustup. In practice
you can use whatever tool you want to flash the device, but this guide
will assume that
probe-run is used (
cargo install probe-run).
Over The Air Authentication (OTAA) credentials will come from these entries in
"dev-eui" = "..." "app-eui" = "..." "app-key" = "..."
Flashing the firmware uses
probe-run which auto-detects the probe connected to your device.
The following command will build and flash the firmware and open the
debugger console so you can see the console debug output.
cargo run --release
If you’re experiencing problems, try setting the
VID:PID values to
that of your probe (you can find that from lsusb once your board is
cargo run --release -- --probe <VID>:<PID>
Once the device is flashed, it will connect to the local LoRaWAN network. Once the network is joined, you can press
the blue button on the development kit to send a test message
num-clicks is the number
of times you pressed the button since resetting the board.
The board features 4 user controllable LEDs. The program will use 3 of them to show the internal status:
Will light up when starting and turn off once it joined the LoRa network.
Turns on while sending the uplink message.
Can be controlled through the downlink message:
