Zephyr and LwM2M

This project is setup to do everything needed to run the Zephyr LwM2M Sample in QEMU with the Leshan Demo Server

Apple Silicon note: Replace qemu_x86 with qemu_cortex_m3 to build but unfortunately, the network will not work.

The instructions below remain valid for Linux hosts with x86_64 CPUs.

Prerequisites

1. Install VS Code
2. Install Docker (If on Windows or MacOS, use Docker Desktop)

Instructions

Open this project in VS Code and let it start the dev container. This will do the following:

• Download and setup Zephyr while building the DevContainer Dockerfile
• Download and run the Leshan Demo Server Dockerfile
• Start the DevContainer with VS Code

Leshan should start on its own at localhost.

1. Build lwM2M Sample

• Terminal 1:

west build -b qemu_x86 /west/zephyr/samples/net/lwm2m_client -DCONF_FILE="prj.conf"

2. Setup network for qemu

Start the net-tools according to the guide

• Terminal 2:

cd /west/tools/net-tools
. loop-socat.sh

• Terminal 3:

cd /west/tools/net-tools
sudo bash loop-slip-tap.sh

3. Run qemu with the build

• Terminal 4:

west build -t run
