Name: TreadmillBridge — BLE Treadmill Data Field
Author: GregLu

Displays real-time speed, distance and elapsed time from a BLE/FTMS 
treadmill via an ESP32 bridge device.

Data is recorded to the activity file and appears in Garmin Connect 
as custom fields (Tread Speed, Tread Dist, Tread Time).

Designed for desk treadmills where wrist-based step counting is 
unreliable. Requires an ESP32 running the TreadmillBridge firmware.

Supported data:
- Speed (km/h)
- Distance (m)
- Elapsed time

Should be compatible with any FTMS treadmill via ESP32 bridge (TreadBLE).
