Sorry from me as well for a very late response.

Have you had any new findings since you updated your Pixel?

Best regards,

Sorry for the very late response.

And sorry for not providing that information with the initial post. I was testing with NCS v2.6.0 as well.

I was using the android bluetooth settings to pair the device which is an audio dk running the audio application with CIS and headset options.

I tried to confirm the behaviour that I described but it seems now that after updating the pixel, the auto connect seems to happen as expected.

But not via directed advertising as this times out and upon normal adv the connection is established as expected.

Hi Laurin,

Which NCS version are you using?

Are you using the phone's Bluetooth settings to bond the devices, or are you using an app (i.e. nRF Connect for Android)?

I was using NCS v2.6.0 and I tested this with a Pixel 7. I found that the LE Audio application reconnected to the phone on reboot, but I did see issues with the direct_adv sample. I was using the nRF Connect for Android app and I needed to initiate a new connection after a DK reboot for them to connect again. After initiating it would take a few minutes before the connection was established.

Best regards,

Maria
