Nordic nRF9160 Development Kit example
This example application runs out of the box on the Nordic nRF9160 Development Kit. It uses the LTE-M modem of the nRF9160 to transmit messages to a CoAP endpoint using DTLS.
The device uses DTLS with a pre-shared key to authenticate against the Drogue IoT Sandbox.
Make sure you have the latest versions (
cargo install <tool>) of these tools:
rustup - To compile the example with the correct toolchain.
probe-rs-cli - To flash the Secure Partition Manager to load applications from the secure mode.
probe-run version 0.3.3 - To run the example. NOTE: Some version of probe-run does not work with this board.
Your device credentials will come from these entries in
username = "..." password = "..."
For Drogue Cloud, the username is stored in this form:
config.toml file for connecting to public Drogue cloud sandbox application could look like this:
hostname = "coap.sandbox.drogue.cloud" # Replace with your own Drogue Cloud instance if you are not using the sandbox port = "5684" username = "device1@coap-workshop" password = "mysecretpassword"
|Make sure to create your application and device is created in Drogue Cloud with the correct credentials (Make sure you use pre-shared keys.)|
Download the bootloader and flash it to the device:
probe-rs-cli download zephyr.hex --chip nRF9160_xxAA --format Hex
Flash and run the application running the following command:
cargo run --release
This will flash the application and show the debug output as the application is running.
