Supported treadmills and Bluetooth communication

Use this reference to understand FTMS, FitShow-style treadmill support, and what Kinni can read from or send to a compatible treadmill.

Kinni supports compatible Bluetooth treadmills that expose a treadmill control/data service Kinni can understand. The two important support paths are FTMS / Fitness Machine Service and supported FitShow-style treadmill services.

Supported treadmill paths

Kinni can work with:

treadmills that expose the Bluetooth FTMS / Fitness Machine Service treadmill profile
supported FitShow-style treadmill Bluetooth services, including legacy NoblePro-style paths

Kinni does not list every nearby Bluetooth device. A treadmill that only exposes Bluetooth audio, generic Bluetooth pairing, heart-rate accessory pairing, or a brand-only app link may not appear in Kinni.

Data Kinni can receive

Depending on the treadmill and Bluetooth path, Kinni may receive:

speed
incline
distance
elapsed time
workout or machine state
treadmill-provided cadence
treadmill-provided heart rate

Not every compatible treadmill sends every field. If a field is missing or unusual, Kinni can only use the data the treadmill actually exposes.

Commands Kinni can send

On supported treadmills, Kinni can send commands such as speed or incline changes during a run or structured workout. Control support varies by treadmill model, firmware, and Bluetooth implementation.

Compatibility limits

FTMS support is useful evidence, not a guarantee that every data field or command behaves the same across brands. The FTMS Checker can inspect a connected FTMS treadmill, but it is a diagnostic tool rather than a certification that every recorded-run workflow will behave perfectly.
