how to get the correct power CTF with SDK

Hello,
I wonder if it is possible in the android SDK to stop sending the offset because the SDK works well with the simulator but a real CTF power sensor (SRM) that no longer works because the offset is recovered whenever the cyclist stops pedaling. This distorts the calculations because the offset is recalculated and it goes up to 1000 values.

I tried the set auto zero method but it does not work either. Even with your ANT + Sampler Plugin.

In case you do not plan to fix this problem can you tell me how to get the frame sent by the sensor so that I can be calculated myself.

I'm not the first on the forum asking how one can recover the frame so I'd like your response is not the same.

Thanks

The Bike Power Plugin does follow the ANT+ Bike Power Device Profile regarding Automatic CTF calibration values and required filtering. Are you seeing the CTF offset value deviate greater than the profile specifies?

A "IRawCtfDataReceiver" interface is available for doing your own calculations on the data.
