Hi,

I have one question to the folks in Bluez group. I saw that we have to specify channel for L2CAP and RFCOMM connections:

struct sockaddr_rc rfcommclient = { 0 };

rfcommclient.rc_channel = channel;

Since Bluetooth uses frequency hopping and hops from one channel to another what is the need to specify this field??

Also, I see that throughout the L2CAP or RFCOMM connections it shows the same PSM value(one we specify for the channel) in the hcidump.

Does that mean no hopping is taking place ??

I am sorry if its a silly question but expecting an answer ??

thanks

robert.
