Loss of bluetooth connection on Zwift-"Controllable"

[Fenar91]

Hi guys,
the bluetooth-connection to the zwift "controllable" isnt possible or not stable (loss of connection repeatedly) but the bluetooth connection to heartfrequency is working. I have no answer for that. Is there any possible solutions for this problem?

P.S. tried with an ipad and an android phone.

Greetings!

For Zwift you need to pair SS2K as a power meter first, then after a few seconds, the controllable trainer selection becomes available. This behavior is the same for all controllable trainers, not just SS2K.

If it's a stability problem (Zwift connects but then the connection goes away), a log would be helpful. You can do this via the web interface (developer tools), "debugging", or better yet over UDP by following this guide: https://github.com/doudar/SmartSpin2k/wiki/Viewing-logs-via-UDP

Good luck!

Testing ESP32's is a pain in the butt - I have a test PCB that I'm using with dupont headers to pre-test before soldering them by hand. Unfortunately, there's no rhyme or reason if you'll get a good one or a bad one. A vendor I used for most of the past year and had many good boards from is the one that sent me 20 bad ones in one batch. I've had other problems with ESP32's I bought off amazon. The majority also don't have a properly specced capacitor for the en pin to enable flashing without pressing buttons during the boot sequence. It's just the pick of the crop these days.

I don't advise desoldering the ESP32 for exactly the reasons you don't want to do it.

Email me at [email protected] and I can send you the necessary parts at cost. Github says you're in Toronto and I'm in downtown - I can mail the parts or we can link up at a convenient location.

Hi Guys,
its crazy but i think i solved the problem with the bluetooth aka. Zwiftconection. My actual phone could not find the ssk neither in nor in zwift.
I tried it now with my old phone, which was reseted and has almost no apps installed. He can find both ss2k, which cant be found in my actual phone, in lightspeed. And zwift ist working too with very fast connection. Is it possible, that some App on my actual phone is blocking the ss2k BLA-Signal? Im really suprised.

Greetings.

Great news!

I know we used to have a lot of issues with the Zwift Companion app running in the background and blocking other apps from connecting but I think Zwift resolved that.

Possibility you have another fitness app running on your phone that is blocking the connection?

Hi Guys,

I will return the ones from Aliexpress. I hope this one will have a way better connection properties.

Cheers
