Dear Marcel,
I wrote a program that builds its own L2CAP packets together.
And now I want to inject these L2CAP packets to a mobile phone.
I begin the transmission with a simple "connection request", but the command is
rejected with reason 0 (command not understood).
Can you tell me how to inject L2CAP packets to HCI without using the BlueZ
L2CAP layer?
best regards
Matthias

look at the l2ping program, because it does exactly this for the echo
command and responses.
