Ok, thank you! In commit you did one mistake: https://git.kernel.org/pub/scm/bluetooth/bluez.git/commit/?id=040bd56a948f4d1ecd6987cdf0ba51779dc0c02a + /* HSP AG role does not provide any features */ + return 0; It should return -ENODATA as AG role does not provide any features, so has_features needs to be set to false.
