Memfault nRF9160 Relay Example

This example builds upon the nRF9160 UDP example by Nordic Semiconductor. It shows how a server that receives UDP packets might relay them to the Memfault servers.

This example uses v1.6.0-rc2 of the nRF SDK.

Installing dependencies

nRF SDK and Zephyr

Install the necessary system dependencies (this command should work as-is on Ubuntu):

sudo apt install cmake python3 python3-pip python3-venv

Clone the repository:

git clone https://github.com/memfault/memfault-nRF9160-relay.git
cd memfault-nRF9160-relay

Create a virtual environment and install the dependencies:

python3 -m venv .venv
source .venv/bin/activate
pip3 install -r requirements.txt

All the steps starting from here mimic Nordic's instructions.

Install nRF SDK dependencies:

west init -m https://github.com/nrfconnect/sdk-nrf --mr v1.6.0-rc2
west config manifest.path firmware
west update
west zephyr-export

Install additional Python dependencies:

pip3 install -r zephyr/scripts/requirements.txt
pip3 install -r nrf/scripts/requirements.txt
pip3 install -r bootloader/mcuboot/scripts/requirements.txt

Compiling and running

Once you've installed all the dependencies, make sure to set your Project Key and a static IP address to your UDP server in firmware/prj.conf:

CONFIG_UDP_SERVER_ADDRESS_STATIC="18.188.13.221"
CONFIG_MEMFAULT_NCS_PROJECT_KEY="owTDJvKithvuHTNj47hwmzUOsQ2qEGbG"

Run this in this repository's root:

west build -b=nrf9160dk_nrf9160ns firmware

Set up the UDP server:

python3 server

Finally, flash the device:

west build -t flash
