FEC with Speed Sensor

We are working on FEC. but the frequency of the speed signals is low.
we have tested with Wahoo as well as Tacx trainers. but both are sending speed signal with low frequency.
as an alternate we decide to use speed sensor.
The speed sensor is sending the speed signal very much realistic.
But problem is that when I establish channel only for speed sensor the signals are ok.
but when I establish first fec channel and afterward a channel for speed then the speed signal doesnot appear.
any body, can give the suggestion, what could be wrong and how I may tackle the situation.

Are you implementing with ANT usb sticks and PC libraries, or an embedded SOC?

Can you give more details about how you establish the channels?

I am implementing the ANT usb sticks and PC libraries. But right now I ahead with the problem.
I could get the speed signals but the frequency of the speed signals is not as much as I expect.
Because when I connect the same speed signal with SImultANT+ tool, the frequency of the signals is very reasonable but when I do with the coding using PC libraries then it is not ok. any idea?

That sounds like the channel period is not correct. I would confirm that you have the channel period set correctly and that you are not receiving many instances of EVENT_RX_FAIL_0x02.
