The native backend works fine - both profiles connect now. I checked with hcidump, for HSP/HFP it looks like the headset tries to connect UUID 0x111f (HFP_AG_UUID) first, does not succeed and then connects UUID 0x1112 (HSP_AG_UUID). > With the ofono backend, a2dp works fine, but I get "not connected" log > messages for HSP/HFP. This seems to be clear now when looking at the result above. Ofono does not support UUID 0x1112, so the connection fails. My controllers both do not show UUID 0x111f as a possible value, neither with the ofono nor with the native backend. With the native backend I see 0x1112 in the list. Any idea why 0x111f is not possible? Am I missing some kernel configuration or something similar? Or is this a hardware issue? Regards Georg
