Bluetooth interoperability problems with some newer mobile phones #779

Open alexgg opened 2 years ago

alexgg commented 2 years ago

Customers implementing a GATT server application have reported communication problems with clients running on newer mobile phones like the Samsung S20.

The problems have been traced to a firmware revision change:

On v2021.10.2, the following exhibit the problem:

linux-firmware-rpidistro

cat balena-image-raspberrypi4-64-2021.10.2.dev.manifest | grep linux-firmware-rpidistro

The bluetooth firmware has been downgraded on ESR 2021.10.4, but both rolling and newer ESR versions are still using the new version which apply Spectra related fixes.

mhazley commented 2 years ago

Hey @alexgg I have encountered this problem on RPi3 using a Pixel 6 - I wondered if you could advise if this change is in latest RPi OS's or just the 2021.10.4 ESR, as I don't see that ESR for RPi 3.

Or a simpler question, is there a version for RPi 3 with this in? I only see 2021.10.2 for RPi 3 32bit

alexgg commented 2 years ago

hey @mhazley this change was only done for 2021.10 ESR raspberrypi branch as it also reverts patches that fix security vulnerabilities like Spectra. Hopefully the root problem should be addressed on the upstream firmware. If this is affecting your fleet please contact us via our support channels (https://www.balena.io/support/) so we can gather some details and propose a solution.
