Usable Bluetooth Codecs

H @all,

Is there a list of all BT Codecs the FP5 on the newest FairphoneOS version supports?
I’m asking because I have Headphones that supports aptX Adaptive, when I connect them, the “Qualcomm aptX Adaptive” popup comes on screen, but in the developers options, aptX Adaptive is greyed out, only Standard aptX, SBC and LC3 are available.

Also, how high is the probability of a future update bringing LHDC(v3) support? It’s already in AOSP and license free, so why not just integrate it?

Hi
The FP5 is equipped with Bluetooth 5.2 LE.
All information’s regarding that standard should be found here:

[Bluetooth® Core Specification Version 5.2 Feature Overview | Bluetooth® Technology Website]

I hope that helps.
All the best :slightly_smiling_face:

Thanks, but not really, no.
The used Bluetooth Standard says nothing about the available A2DP Codecs.

As far as I know the codecs are choosable when a Bluetooth device is connected.

Then I found a bug. Because like I said, I have a pair of Headphones that supports aptX Adaptive, and on other phones (with A13) it connects correctly with aptX Adaptive in the developers options.
On the Fairphone, it looks like this:

What happens if you choose Qualcomm aptX?

Then the Headphones use aptX, but that’s not the point, because aptX ≠ aptX Adaptive

I would ask support to get a confirmation about the specifcations

Has anyone been able to find Codec information?
