Trainer and modes
The trainer does not change resistance
If the trainer gives power but does not change resistance, VinApp may be reading data but not controlling the trainer.
Recommended steps
- Check that the trainer is connected as a controllable device.
- Check that it is not connected to another app that has control.
- Check the mode selected in VinApp.
- If you use Bluetooth, remove old manual pairings from Android.
- Turn the trainer off and on.
- Try a simple workout with clear power changes to verify control.
