ESP32 UWB DW3000

The DW3000 library in this repository was developed by NConcepts.

This project uses MakerFabs DW3000 UWB ESP32 modules.

This code is written for our work "UMotion: Uncertainty-driven Human Motion Estimation from Inertial and Ultra-wideband Units".

Description

Anchor-tag (AT): measuring the distance from one tag to multiple anchors

Distance-matrix (DM): measuring the distance matrix among all nodes

Getting started

1. Clone the repository onto your local system.
2. Connect the ESP32 UWB3000 and modify upload_port and monitor_port in platformio.ini.

   U1 is the initiator

   • AT: env:at_sstwr/dstwr_u<1-6>.
   • DM: env:dm_sstwr/dstwr_u<1-6>
3. Modify NUM_NODES and INTERVAL in uwb.h
4. Upload the code pio run -e <env name> to each device
