lora-discovery example
This example application runs out of the box on the STM32 LoRa Discovery Kit (B-L072Z-LRWAN1).
Prerequisites
Software
To build and flash the example, you need to have rustup.
You can use whatever tool you want to flash the device, but this guide assumes
that probe-run
is used (cargo install probe-run
).
Configuring
Over The Air Activation (OTAA) credentials will come from these entries in ~/.drogue/config.toml
:
"dev-eui" = "..." "app-eui" = "..." "app-key" = "..."
Flashing
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
powered).
cargo run --release -- --probe <VID>:<PID>
Usage
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 ping:<num-clicks>
, where num-clicks
is the number
of times you pressed the button since resetting the board.
LEDs
The board features 4 user controllable LEDs. The program will use 3 of them to show the internal status:
- Red
-
Will light up when starting and turn off once it joined the LoRa network.
- Green
-
Turns on while sending the uplink message.
- Blue
-
Can be controlled through the downlink message:
led:on
orled:off
.
