This example application runs out of the box on the RAK811 family of microncontrollers. The RAK811 is based on a STM32L151 and a Semtech Sx1276 radio.
|The random number generator used in this example is vulnerable to tampering if a user knows the oscillator frequency of the chip. The STM32L1 does not have an on-board random number generator peripheral.|
Verified on the out-of-production RAK811 Tracker Node, which has been replaced by:
All boards with the RAK811 chip should function, but may have different capabilities in on board perpiheral support.
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>
