PM5 Bluetooth

By the Watta Team · Updated March 2026

PM5 Bluetooth: The Concept2 PM5 Performance Monitor includes Bluetooth Low Energy (BLE) connectivity, allowing it to wirelessly transmit workout data to compatible apps and devices.

What is PM5 Bluetooth?

The PM5 is the performance monitor attached to all current Concept2 ergometers (RowErg, SkiErg, BikeErg). It includes Bluetooth Low Energy (BLE) and ANT+ wireless connectivity, enabling real-time data transmission to smartphones, tablets, and heart rate monitors. Bluetooth pairing allows compatible apps to receive stroke-by-stroke data during a session, including split time, stroke rate, distance, watts, and calories. However, Bluetooth connectivity can be unreliable in gym environments with many competing signals, and pairing sometimes fails or disconnects mid-session. The PM5 also stores up to 100 recent workouts in its internal memory, which can be accessed via USB or the Concept2 Utility app.

How Watta Uses PM5 Bluetooth

Watta bypasses Bluetooth entirely by using AI-powered OCR to read the PM5 screen from a photograph. This eliminates pairing issues, connection drops, and the need to set up Bluetooth before every session. Simply photograph your PM5 screen after your workout and Watta extracts all the data instantly.
