Supported treadmills and Bluetooth communication

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.

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.

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.

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.

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, and Kinni may use a passed result to remember local compatibility settings for that treadmill. This mapping is local evidence, not a public certification that every recorded-run workflow will behave perfectly.

If your treadmill exposes standard FTMS, Kinni should try the generic FTMS path first. Brand-specific or proprietary Bluetooth links that do not expose the standard FTMS treadmill service are not covered by the generic FTMS path.
