Hi, I am using 5.34 bluez-5 stack on linux kernel version 3.14. when I create rfcomm connection and do cat /dev/rfcomm0 and from other terminal send AT commands to rfcomm0 I get proper response and other characters continuously(> ??? ...) echoed from rfcomm0. If I do the same from bluez4-101 I get proper response with no other characters. What is the proper way to do rfcomm communication ? I am trying to connect to a OBD device via rfcom socket.
