Direct Connect disconnects from Power/Cadence in Zwift if idle?

[yetanotherbrian]

I'm trying to diagnose an issue of connections being lost mid-ride on Zwift, and want to check what expected behavior is before creating an Issue. I had all sorts of connectivity issues on an RPi 3B+ over the weekend on 2hr rides and then zero problems on a 1h45m ride using an RPi 5. I positioned the Pi 5 closer to the PC thinking the 3B+ was getting interference from where it was located.

But the immediate issue...

If I start Zwift, selecting QZ as my resistance and the Direct Connect device for Power and Cadence, should it ever drop the connection from Zwift if sitting idle?

As of this morning I am running the latest build on an RPi 4 and found Power and Cadence with "No Signal" when I checked on it three hours later. QZ still showed active for the resistance. I have logging turned on. I tried turning the cranks a couple times to see if it would reactivate but it didn't seem to. I then unselected both Power and Cadence connections and reselected, and after a couple turns of the cranks on the bike the top left power/cadence/watts fields reactivated.

From the logs it looks like it stayed connected for 151'ish minutes before disconnecting, and I discovered it around 13 minutes later:

Always use wahoo kickr so raspberry and pc will comunicate over wifi.

If there is a drop on this communication you have to check the wifi signal or simply put a cable on your raspberry if you didn't already
Let me know

Thanks.

During a ride this evening the Power/Cadence disconnected twice and the second time it happened I also lost the other riders in Zwift (likely the PC dropping the WiFi connection). I suspect it is interference between the Bluetooth on the RPi and the 2.4 GHz WiFi on the PC -- the RPi was sitting on top of the PC case a couple inches away from the PC's WiFi adapter.

I've moved the RPi a couple feet away from the PC and will leave QZ connected to Zwift overnight and see if it is still connected in the morning. If there is still a problem I'll put a cord on the PC's Bluetooth adapter and test again.

Ok I suggest to use lan network on both raspberry and pc to avoid this Roberto Viola Software engineer and open source enthusiast http://robertoviola.cloud Il giorno mer 26 feb 2025 alle 07:46 yetanotherbrian < ***@***.***> ha scritto:

I had an 8-port gigabit switch at the PC, but removed the wiring a couple weeks ago and would prefer to not put it back. And eventually I would like to use the least powerful RPi necessary for the virtual shifting and hoping that a headless Zero 2 W works (but for now it is too slow to comfortably use the Desktop).

If moving the PC's 2.4GHz WiFi adapter away from the BT doesn't work I'll order a 5GHz adapter, and if that still doesn't solve the problem I'll get a 5GHz WiFi bridge and run both PC and Pi on wired ethernet.
