Favero Assioma - Pedal Power Meter

Latest suggestion I was given was to 'forget' the device and pair again on each unit. Did a trainer ride last night, no drop-outs when connected with bluetooth to a phone and ant+ to a head unit. Turn on the watch and pair through ant+, started to see some issues on the head unit, although the phone was fine. After a couple of minutes everything appeared OK on all fronts, but I'll reserve judgement until after a longer ride at the weekend.

I use ANT+ to devices & laptop. Only time Bluetooth is used is to upload to my phone from my Edge or Watch.

I wonder if there's an issue with my pedals that was also causing the lack of cadence on Zwift.

Latest theory that the different devices had different crank lengths set, and this is enough to cause the drop-outs. Three rides complete since repairing the devices and all appears clean.

So they arrived back yesterday. Still to be opened! I don't know what the paperwork inside will say, but there's a sticker on the outside talking about repairing the ANT+ (which would explain the dropouts). An email I got also said they'd also been factory recalibrated.

Will report further when I actually get them on a bike.

Two rides done on them since coming back from factory. So far so good!

Ugh, signal loss again Rolling Eyes

I've sent them another tech support message...

I have started experiencing signal loss once again with these pedals. They came back to the factory in November last year, and whatever was done it fixed the problem until now. As per the last time. all head-units and Zwift (PC) experience loss of signal from the pedals. On this occasion, I feel there is the potential that I have done something that could have affected the signal(?)...
- I changed cranks - that is I removed the pedals and reinstalled (but this is never usually a problem!)
- I have a new Garmin 935 that I have paired with the pedals.
- I performed a Zero Offset calibration on the Garmin 935, but not on the Edge 520 that was also connected (I declined when prompted)

Whilst there is a tendency to believe that something was interfering with the signal, on many occasions I have used the pedals with multiple Garmin units & Zwift (PC) and with various electrical devices present (the PC and a fan) with no problems at all. So I am wondering if it is something related to my list above?

It can't be a coincidence given the changes above can it? Something must have affected the pedal signal. I was pedalling like mad at the start of a Zwift race and it dropped to Zero and everyone rode off. NOOOOOO! It seems that when I put out more watts, it's more likely to drop-out given the session yesterday, it was dropping on climbs for example.. Hmm.

This sounds like the problem I had, multiple drop-outs when connected to 2 garmin devices. I had to make sure the crank length was set the same on both units, and deleting the pedals from both units and doing a fresh connect seemed to fix it. I’ve seen occasional issues when the 2nd unit tries to connect, if I hit stop it recovers. At the time my indoor training was connected via Bluetooth and this never seemed to have an issue. Not entirely sure what it was, but I’ve been running without issues for months now.

so you're connected to 3 devices, Zwift (on a PC?), an Edge 520 and 935

When I am on Zwift I just connect to the PC, otherwise I get drop outs. While riding normally I just connect to Edge 1000. I think that the only time I had issues with Assioma was when connected to multiple devices. The main reason I don't connect to multiple devices is that I get the same activity recorded multiple times on Garmin Connect

I'm away now, but I think it could be crank length disparity. I went through the settings in the Assioma app and noticed it was 172.5 and corrected that to 170. I expect it's different on the Garmin's i.e. correct on the Edge at least, and need to configure the watch.

Yes, 170 by choice on TT bike; aftermarket chainset.
