[Bug]: T-Deck Bluetooth Won't Start w/ v2.5.19.f9876cf

Hardware

T-Deck

Firmware Version

2.5.19.f9876cf

Description

I have two T-Decks that work as expected using v2.5.18 but on v2.5.19.f9876cf the Bluetooth functionality stops working and devices never show up in BLE scan.

Using "--set bluetooth.enabled true" does nothing and "--get bluetooth.enabled" returns false always. Need to run "--set bluetooth.enabled true" after reflashing v2.5.18 to get it to work again.

Relevant log output

Thanks for the report. A couple questions to help us understand:

1. Do you have wifi enabled?
2. What role is the device set to?

If you could connect it to a computer and get logs (eg click serial monitor on flasher.meshtastic.org ) that would be very helpful.

Are you using the new MUI?

1. WiFi was enabled on one T-Deck when it was flashed, but disabled on the other when flashed and both ended up in the same state. I have tried to explicitly disable WiFi using "--set network.wifi_enabled false" before enabling Bluetooth but also didn't work. Both devices seemed to function normally otherwise one with an uptime of ~55 hours.

2. One device has role set to Client and the other Client Mute.

Not using MUI with either of these currently just vanilla v2.5.19.f9876cf.

Can fetch logs tomorrow but I didn't see any obvious errors or warnings.

I just got mine delivered today and got it setup with the app/Bluetooth then I decided to update the firmware. After that I am unable to get it to reconnect. The app does not even detect the device. I have also removed the Bluetooth device from the phone and removed the app. Reinstalled the app issue persists. Not a good first impression..

So I just used the website to try and enable Bluetooth but that did not work. Anyway to get the Bluetooth back on?

Rollback to the stable firmware. 2.18

Noticed the same thing last night. I was on 2.5.18ebafc with T-Deck Plus. Flashed to 2.5.20.4c97351 lost bluetooth.

Rolled back to 2.5.18 and ran "--set bluetooth.enabled true" to get it working again.
