ErgBridge

Use your iPhone as a Bluetooth power meter for your Concept2 PM5.

ErgBridge reads power from a Concept2 PM5 ergometer monitor over Bluetooth and re-broadcasts it as a standard BLE Cycling Power Service. Any app on a separate device (Mac, PC, iPad, Apple TV) that can pair with a Bluetooth power meter will see your iPhone as one.

Architecture: PM5 → iPhone (this app) → receiver on Mac/PC/etc.
