Description

This project demonstrates how biosignals — such as ECG and temperature readings — can be transmitted over a LoRa Meshtastic mesh network in real time.
By using a Seeeduino XIAO as the signal acquisition node and a LoRa-E5 module for communication, the system captures analog signals at 500 Hz, compresses them, and sends them as Base64-encoded chunks across the mesh.

To ensure reliable communication even when several users are active in the same area, the system implements multiple optimization strategies:

Signal segmentation (chunking) for efficient transmission.

Timing delays between packets to avoid network congestion.

Data compression and normalization to reduce payload size.

Dedicated channels and hop-limit control to prevent flooding the mesh.

The result is a low-power, decentralized biosignal transmission system suitable for remote health monitoring and field deployments.
