I have two bluetooth devices (Linux PC and Android Phone). Both support BR/EDR. I have written an application that transmits data over an l2cap connection. 1.) How do I force the connection to use EDR only? According to the spec I need to set "Packet_Type" with the appropriate bits. I'm using the BSD socket API. I don't see an option in setsockopt() to set the Packet_Type parameter. Is there another approach to accomplish this? 2.) Is there a tool I can use to verify that EDR is used? Here is some additional information about the devices. Both show support for DH3. Am I reading this correctly to mean that 3-DH3 is not supported on either device? My understanding is the max speed for 3-DH3 is 3Mbit /sec, while DH3 is limited to 2.1Mbit/sec.
