Hi,<br><br>I have one question to the folks in Bluez group. I saw that we have to specify channel for L2CAP and RFCOMM connections:<br><br>struct sockaddr_rc rfcommclient = { 0 };<br><br>rfcommclient.rc_channel = channel;<br><br>Since Bluetooth uses frequency hopping and hops from one channel to another what is the need to specify this field??<br><br>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.<br><br>Does that mean no hopping is taking place ??<br><br>I am sorry if its a silly question but expecting an answer ??<br><br>thanks<br><br>robert.<br><br><p>&#32;
