[Bluez-devel] callback for L2CAP disconnection

[Bluez-devel] callback for L2CAP disconnection

[Carmine Pirro]

Does BlueZ stack provides a callback mechanism for L2CAP
connections/disconnections?

Thank you, Carmine.

what do you mean by callback? The BlueZ L2CAP implementation provides a
full sequential packet socket interface.

Fwd: [Bluez-devel] callback for L2CAP disconnection

[Carmine Pirro]

The following is what i have to do:
a device A is connected to a device B.
When device A disconnects, a process on device B has to print the
device A bluetooth address on the screen with a appropriate message.

Thank you, Carmine.

Why don't you use select or poll as in any other socket based application ?
You can also filter HCI disconnection events by using raw hci sockets ...

this is all about socket programming. Take a look at functions like
poll(), getsockname(), getpeername() etc.
