Hello,

I wonder how one can access Bluetooth Chip via a serial port?
As I read on the Internet that normally Bluetooth CF card simulate itself
as a serial port for accessing the BT Chip.

So, in this case, one can access the low-level functionality of the BT Chip
as accessing a serial port, however, I wonder how I can figure out what
port BT CF card is simulating? I have an Anycom CF card, I cannot find
the serial port at all.

Any comments?

Thanks

One can use a physical serial port to access a BT chip. The BT software
itself then resides on a PC or whatsoever, the lower layers (HCI, LM,
BB) resides on a seperate processor that has direct access to the BT
radio. The physical link transporting the HCI commands, events and data
can be a usb connection, a serial connection or something else that is
able to transport HCI.

On the PC side, the BT software starting from L2CAP and upper layers
reside. On top of these layers profiles are implemented that can a.o.
emulate logical serial ports. These logical serial ports have nothing
to do with the phisical serial line between the host and the BT controller.
