Hi Marcel,
>> Symptoms:
- The connection request times out.
- bt_io_accept() is being called but the accept_cb (=connect_cb) only gets called when the request times out.
- the device is stuck in the CONNECT READY state and never reaches the CONNECTED state
Any ideas how I could analyze/solve that problem? I'm stuck on this for many hours already...
what does btmon actually tell you about what is going on with HCI.

There is no connection related HCI activity going on at all on the Nexus
4 side. You can see from the debug logs that I sent before, that the
connection is being initiated correctly. The bt_io_accept() call does
return without error, just the accept callback never gets called. To me
it seems as if the Nexus4 was not responding to the incoming connect
request.

The advertising being aborted on connect is not a problem. The
advertising part works flawlessly. Connecting
