Tacx Vortex & Garmin 245 stopping connection with Pixel 6a

Hi,

I’m on a Pixel 6a and until this week my Tacx Vortex and Garmin Forerunner 245 (HR broadcast) connected fine to TrainerDay. Now the app finds them but won’t complete the connection.

I’ve tried: restarting phone/trainer, reinstalling the app, forgetting/re-adding Bluetooth devices, airplane mode, and making sure no other apps are paired. Still no luck.

Has anyone else had this issue or found a fix?

Thanks!

Sorry to hear. We made changes that caused this but it seems most users that had an issue have figured out how to resolve it.

We have a pixel 6 and pixel 7 we are testing with and other tacx trainers and garmin watches and it all connects fine. If you said you had Samsung I would have a better idea what I thought the problem is but with pixel I am now confused.

You can go to settings/apps/trainerday and review the permissions we used to use location services and now we are using direct bluetooth connections.

What version of android do you have?

Thank you for your reply.

I’m using Android 16

Yeah me too on Pixel 7 A16 with Garmin 955. But other users have issues connecting to Garmin watches. Only a few samsung users have issues connecting to a trainer now. Your case is harder unless it is permissions but usually permissions won’t let you even see the devices. You could try just keep clicking on + and - in our app. It’s 2-phase one is pair with device the second is setup notifications so we can get power, hr, cadence… and it is the second part that is failing. The current version has re-try for heart rate. One thing you could try that might “break the lock” on your watch is make sure broadcast is on and disconnect it from your android settings.

You also could try logout of our app. That might clear something that uninstall does not. Hard to believe but android has some strange caching that I don’t understand.

I have another idea which is restart your trainer and power off your watch and back on.

We do have a new version we are just waiting on play store that has re-try logic that might help it connect to one or both of your devices.

Thank you, Alex.

Tried the logout/login approach with no joy. Have tried clearing cache in both the app and Bluetooth, again with no luck.

I’ll try powering down watch and trainer again.

I’ll look out for the new version too.

Thank you for your help

Hi.

I’ve redownload the app this morning. I can now connect the Garmin, which is good. The app is finding the smart trainer but still won’t connect.

Interestingly, the app first identifies the trainer as the whole smart trainer but then won’t connect. Going out and back in to the connection screen it then identifies it just add the power meter on the trainer. It flips between the two.

But as it stands I can’t connect. I suppose if it continues I’ll have to cancel my subscription.

Thank you

Sorry to hear. You did not mention, completely uninstalling our app and reinstalling.

Would you mind going here

https://trainerday.com/ble-testing.htm

and seeing if you can connect and if so download the report after 20 seconds or so and send it to me at support@trainerday.com

I have an idea what this might be.

Thank you for the email.

I have tried connecting to the link but it keeps failing, I’m afraid.

Thank you so much for your help.

Clicking the link in alex’s thread didn’t work for me, but copying and pasting the url from the post into my browser bar did work

I managed to connect big when pairing I got this error message saying the “GATT Server is disconnected. Cannot retrieve services.”

Oh sorry I forgot to mention this should be done on windows or mac in chrome. It should have told you that. It looks like bluetooth is working on your device though. That message still might help. Let me do some research.

Sorry, my misunderstanding. I’ll give that a go.

I’ve just emailed that through to you now.

Thank you for your help.

I got your email but I will just respond here. That is very interesting. It really should be working in our app but we will need to do some deeper research. It seems for sure we should be able to get this fixed quickly. I will keep you updated.

I should ask. Did you uninstall our app and reinstall it?

Yes. I uninstalled and reinstalled it on my pixel 6a this morning.

Brilliant. Thank you
