Developer Bridge crash on Sense/Versa 3

[JonFitbit]

If you're developing using a Fitbit Versa 3 or a Fitbit Sense and you're experiencing a reboot when using the developer bridge, complete this form for access to a beta firmware.

It's only for Versa 3 and Sense, and doesn't include anything else, so only complete the form if you need it. https://forms.gle/j7fzYb9evrtCxs879

I don't experience any reboots, but my Versa 3 will not connect to the Developer Bridge. It seems to time out and give up after about a minute of circling around the toggle switch. I am logged in to the developer environment through the CLI. The Fitbit Simulator connects fine. Any ideas what could be the cause?

Thanks

It's actually connected, but the Settings app isn't showing it. Just try connecting from the CLI. `connect device`.

If you register for the beta firmware, you can update the Settings app to fix this issue.

So it works as long as you don't have the Sense connected to the charger. If you connect it to a charger, after a few seconds without fail it'll crash and restart the device.

Edit: Actually to narrow it down it seems to be whenever it's taken off a wrist or at least would ask for the password again.

Thanks Jon, that worked 🙂

Hello Jon,
I am under firmware 44.128.2.35 on my sense and the developer bridge now works fine without crashing my sense.
However, I cannot access the ECG application. Is there a way to have the ECG in this firmware version, or a way to revert back?
Regards

I can confirm the same behaviour with the ecg app. It's asking us to make sure we are on the latest update

I updated to Fitbit OS 5.1 (128.4.15) on Fitbit Versa 3. This crash seemed to fix it.
