Hi,<br><br>&nbsp;I wrote a program to create a bluetooth connection using hci_create_connection&nbsp; and the devices get connected but how do I send and recieve packets using this connections. My aim is to test the communication link between the devices using different packet types(DM1,DM3,DM5...)<br><br>Can someone please give me a hint on how this can be done. I have been struggling a lot as I am new to Bluez and C programming.<br><br>thanks<br><br>Marco.<br><p>&#32;
