Read from USB trainer error

[tkathulevej]

Hi,

I'm I the only one getting this error now and then:

This happens not always. - Maybe 1 out of 10 training sessions.. I seems also to never happen at low intensities (only after longer intervals at +200W I would say).

In the beginning I thought this had something to do with maybe a faulty Fortius motor unit overheating, but now I have had the opportunity to use FortusANT with 2-3 different Fortius trainers (T1941/1932) and even different kombinations of motor and head unit. - And I still see the error now and then :-/ ....Only way to recover from is to fully shut the FortiusANT program and restart (...meaning your training session in BigRing VR which I use is spoiled.

I've not tried to run Fortius with logging. Maybe I should?

The real issue is that there is no error recovery on the serial on the interface to the headunit. If insufficient data us received, FortiusAnt tries to recover, but... Not always successful.

Om my trainer it also happens sometimes, properly reconnecting helps. The error also happens when the mains cable is not properly connected; perhaps it causes interference or so.

Any suggestions welcome, no solution found until now

Logging will help you to understand the problem but will not help me to investigate. It will confirm that records are received incomplete

[WouterJD]

I assume you disabled pedal stroke analysis, causing to tune down the sampling frequency. Not all headunit manage to respond fast enough

...Okay, thx for the information. - And yes, stroke analysis disabled.... /tka

Hi how are things?

[WouterJD]

Since there is no communication here, I assume can be closed. If not happy to reopen
