Hello,

I am using WICED SDK 6.4 for 20706. The application is HFP audio gateway. Created out of the demo hci_audio_gateway. Testing against Jabra Boost v1.1.0. On some occasions when I power off the headset and power on, the peer initiated rfcomm is getting disconnected at some point during the AT cmd-responses. This occurs almost 50% of the repetitions when tested against with this specific model of the headset.


The callback  wiced_bt_port_mgmt_cback_t reports these messages as a server:

Satus = 19, Port Handle: 0x0001

On the occasions I see the Success, HCI traces are showing following order of RFCOMM channels:

When Headset is powered up:

  • Signalling Channel Open
  • AG Channel Open

When peer is powered down:

  • AG Channel Close
  • Signalling Channel Close


On the occasions the SDK callback wiced_bt_port_mgmt_cback_t reports Status 19, I see the following order of HCI traces.When Headset is powered up:

  • Signalling Channel Open
  • AG Channel Open
  • Signalling Channel Close

I suspect that coinciding with the above signalling channel close callback reports status 19. Can anyone comment what may be an issue?

Thankyou
Praveen

Will the problem with all the headset. Or it only happens with some specific headset?

Is this a common problem or compatibility problem?

On this specific headset, it is highly repeatable (~50%). Whereas with other headsets cannot say for sure, seen atleast once with Jabra Talk25.
