I ride a Kickr and connect it to my windows PC via Ant+. I have two Ant+ dongles and record in Zwift simultaneously with Sufferfest. My Kickr is on the latest firmware. All too often, the Sufferfest software just seems to stop recording my pedaling and I get drops in my cadence and power. SUFFER…

Tbh, I’m not sure I’ve tried that. I was just looking at the Help section and it talked about interference, so I’ve ordered a 1.5m extension with 4 USB ports, so will try moving the dongles closer to the Kickr.

Echo’ing @JohnK comment. Can you please run your next couple of workouts just running your SUF workouts without attaching to Zwift and let us know? In the meantime - can you screenshot the double dongle setup? one screenshot of the Zwift connections page once it’s up and running one screenshot o…

Also, are you downloading the SUFF video in order to run it. I had a similar problem starting out, and (with the minions) determined it was being caused by interference during streaming.

[image] Martin: I assume that you are using the FE-C connection for SUF and the basic PWR reading for Zwift? Is that right? Tbh, I don’t know. I open up Sufferfest, let it connect to everything, then open Zwift, let it detect things and disconnect the control. [image] CPT_A: Also, are y…

I have had the same issues between SUF and Zwift when using BT and ANT+ and it happens regardless of which is using which connection. I don’t know if this is technically true, but in my experience SUF seems to care more about correct data than a smooth connection and so if no data is received, none …

That’s interesting, but I have seen data ‘stick’ in Sufferfest for 3 or 4 seconds. Sometimes I feel like it takes me stopping pedalling for a second to make it start back up again.

It is an old error. You cannot mix Ant+ and BT in Sufferfest for Windows. So either disable BT on the PC or connect all using BT only. Then in ERG mode changes in targets is spot on the second.

Interesting, thanks. I’ve turned BT off. I did a session using the extension for the dongles and there was also no video for the workout and it went along without a hitch. There was the occasional delay in ramping up the resistance though, so I’ll see if turning off BT fixes that.

I prefer using only BT since my headset is connected using that. Though I had to buy a Wahoo Tickr heartrate to archive that
