Hi,
I am trying to work with L2CAP channels over BLE. The service discovery, PSM
lookup (via characteristics) and such all work fine, so no issue there.
The channel connects and I am able to exchange a packet or two with the remote
device before the input stream is closed unexpectedly.
Meanwhile, the console reports the following CoreBluetooth messages:
error WARNING: Unknown error: 431
error WARNING: Unknown error: 436
As far as I can tell these error codes are undocumented and decent
CoreBluetooth L2CAP documentation is incredibly scarce. Does anyone know what
they mean?
Neil
