[bluetooth] Sending ACL Packets

["Andrew McKay" <mckay@Ms.UManitoba.CA>]

Hi

For my undergrad thesis in Computer Engineering, I'm working on transmitting
data from a HC11 through bluetooth to a PC.  The problem I am having is with
ACL packets.  I can successfully make a connection between bluetooth boards,
but am now trying to request a L2CAP connection to the other board.  I'm
sending the following packet to the bluetooth board, but am getting no
response on either end.  I am sending the L2CAP connection request packet to
the signalling channel (0x0001) to request a new channel with an end point
of 0x0040, which is the first open channel.

The command I am sending to the bluetooth board is as follows:
0x02    ;ACL header
0x01    ;LSB handle
0x20    ;MSB handle & bc=00 & pb=10
0x0C    ;LSB ACL length
0x00    ;MSB ACL length
0x08    ;LSB  L2CAP packet length
0x00    ;MSB L2CAP packet length
0x01    ;LSB L2CAP CID
0x00    ;MSB L2CAP CID
0x02    ;Connection request command
0x01    ;Unique Identifier
0x04    ;LSB L2CAP command length
0x00    ;MSB L2CAP command length
0x01    ;LSB PSM
0x10    ;MSB PSM
0x40    ;LSB Source CID
0x00    ;MSB Source CID

I have a couple of questions about this.  First, does this command seem
correct, and if it is, is there anything else I have to do after
establishing a connection that I have to do before I can send and ACL
packet.

Thanks for your time,
