ALADIn: Autonomous Linear Antenna Delay Inference on Resource-Constrained Ultra-Wideband Devices

This project contains the PoC for ALADIN: All-to-all Linear Antenna Delay Inference on Ultra-Wideband Devices. It is currently under revision and clean-up.

Setup

Setup Zephyr and West as usual. As the Decawave Driver does not allow precise timings, we added some overrides which need to be manually applied (see override directory). As an alternative, you can checkout the related Zephyr feature branch. Tested based on commit 6d56b829423056819c4baaafd6c66957752e22f8, while commit eeb4434d2eb5f2c978c59a439688c1f3f46e8bf8 has been reverted due to scheduling exceptions (already included in the overrides).

Build

Build the project for the Decawave DWM1001 module:

west build -b decawave_dwm1001_dev --pristine auto

You can then flash the boards one by one:

west flash

Build With Docker

You can also use the included Dockerfile / docker compose file configuration to build (warning this might take a bit of time):

docker compose up -d --build

docker compose exec -it build /bin/bash
cp -Rf /app/override/* /zephyr/zephyr/
west build -b decawave_dwm1001_dev --pristine auto

To run and deploy on Lille:

scp ./build/zephyr/zephyr.elf USER@lille.iot-lab.info:~ && ssh USER@lille.iot-lab.info 'iotlab-experiment submit -d 5 -l lille,dwm1001,1-14,zephyr.elf'

In the container you can also easily install script dependencies as follows:

pip3 install numpy pandas matplotlib

Scripts

Evaluation scripts are in the scripts directory.
