Bluetooth: airpods do not reconnect correctly

oleksii · 19 September 2021 16:08

Hi all!

I successfully connected two pairs of headphones to the raspberry pi 3: DALI IO-6 and airpods.
DALI IO-6 works just fine, incl. after reconnecting.
But airpods are not – after reconnecting there’s no sound and corresponding device in audio output device in Settings/System/Audio.

As I can see, the difference is in ServicesResolved status: after reconnecting the ServicesResolved: no.

DALI has no that ServicesResolved stuff at all.

To successfully reconnect airpods I’m doing the sequence as follows (in osmc GUI):

go to ‘My OSMC/Network/Bluetooth’;
choosing airpods in Paired Devices, pressing ‘Enter’, then choosing ‘Re-connect’;
during few seconds taking out at least one headphone from the box;
voila - all works fine: the airpods item is in the audio output device list in Settings/System/Audio.

Here’s my bluetoothctl output for:
i) reconnecting Dali (line 6);
ii) reconnecting airpods unsuccessfully when opening the case and taking out the headphone (lines 7&8 plus info shows ServicesResolved: no);
iii) reconnecting airpods successfully with the sequence described above (lines 9&10).

Is there any way to get airpods reconnected without additional efforts just like Dali?

Thanks in advance!

You could try to remove it in bluethoothctl and then try again:

agent on
scan on
pair <address>
trust <address>
connect <address>
scan off
agent off
quit

Also did you try with a single bluetooth audio profile only (romiving the Dali) to ensure that is not where the problem comes from.

In fact, I tried Dali just to check if their behaviour is the same as AirPods. And I found out that they work as expected (and the same way they work on my Vero 4k).

I deleted everything except a BT keyboard and did as you asked – AirPods do not fully reconnect. By ‘fully’ I mean that they stop/start playback when I double-tap but there still no audio device…

Here’s an output of all performed actions:

Will try to connect AirPods to Vero 4k today and post a result.
