Open Rowing Monitor, https://github.com/laberning/openrowingmonitor
|
|
|
|
This manager creates a module to listen to ANT+ devices.
|
|
This currently can be used to get the heart rate from ANT+ heart rate sensors.
|
|
|
|
Requires an ANT+ USB stick, the following models might work:
|
|
- Garmin USB or USB2 ANT+ or an off-brand clone of it (ID 0x1008)
|
|
- Garmin mini ANT+ (ID 0x1009)
