Bluetooth vs ANT+ devices
Use this reference when a sensor or treadmill advertises Bluetooth, ANT+, or both.
Kinni’s current device-connection flows use Bluetooth. When you choose a treadmill, heart-rate monitor, or foot pod for Kinni, check the Bluetooth support first.
What Bluetooth means for Kinni
Section titled “What Bluetooth means for Kinni”Bluetooth is the connection path Kinni uses on the run setup screens:
- Treadmill scanning looks for supported treadmill Bluetooth services, including FTMS and supported FitShow-style services.
- Heart rate monitor scanning looks for the Bluetooth Heart Rate Service.
- Foot pod scanning looks for the Bluetooth Running Speed and Cadence service.
If a device advertises the right Bluetooth service, it can appear in the relevant Scan & connect list.
What ANT+ means
Section titled “What ANT+ means”ANT+ is common in sport sensors, especially older heart-rate straps and foot pods. Kinni does not use ANT+ as its app connection path. A sensor that is ANT+ only should not be expected to appear in Kinni’s Bluetooth scan.
Some devices support both Bluetooth and ANT+. In that case, enable the Bluetooth broadcast mode and make sure another app or watch has not already taken the Bluetooth connection.
Choosing a device
Section titled “Choosing a device”Before buying or troubleshooting a sensor for Kinni, check for these phrases in the device specification:
| Device type | Look for | Kinni use |
|---|---|---|
| Heart-rate monitor | Bluetooth Heart Rate Service, Bluetooth Smart, BLE HRM | Live BPM during a run |
| Foot pod | Bluetooth Running Speed and Cadence, BLE RSC | Speed, cadence, stride, and distance data |
| Treadmill | FTMS Bluetooth, Fitness Machine Service, supported FitShow Bluetooth | Treadmill data and control |
If a dual Bluetooth/ANT+ sensor does not appear
Section titled “If a dual Bluetooth/ANT+ sensor does not appear”- Put the sensor into Bluetooth mode if the manufacturer provides separate modes.
- Disconnect it from watches, bike computers, and other phones.
- Restart the scan in Kinni.
- Check the battery, because low battery can make Bluetooth advertising unreliable.
- Confirm you are scanning from the matching Kinni card: heart-rate monitors and foot pods use separate scan screens.
