Hi all,
I'm trying to do something really simple in the bluetooth environment.
I attached a USB bluetooth module (from A7 engineering) to a Linx PC,
and I attached a serial module to a windows PC. This serial module has
the complete stack, and I just interface to it with ASCII commands over
a serial port profile. I want to simply send ASCII text across a
bluetooth serial connection between the two computers.
I have been able to do this successfully with a windows host. Here are
the steps I'm taking:
* On the Windows side, I connect to the serial bluetooth module,
configure the baud rate to 9600, no HW flow control, etc.
* On the Linux side I start the hcid and sdpd services.
* Then I search for the remote bluetooth device using "hcitool
inq" and I see it.
* I establish a connection using "hcitool cc <bt address>".
* Finally I use rfcomm to make a serial connection: "rfcomm
connect 0 <bt address> 1".
The windows side recognizes a connection is made, but I am unable to get
data across.
I have found no way to establish baud rate. Is that necessary across
bluetooth?
I am expecting to just type into a window and see the characters show up
in the external window. This works when both sides are Windows machines
using hyperterm.
Instead, when I type on the windows hyperterm, I get the ascii
characters repeated (is the Linux side bouncing the characters back?).
On the Linux side, when I type in the window, nothing really happens.
Any help/advice would be helpful.
Thanks in advance.

You might wanna use "rfcomm --raw connect 0 <bdaddr> 1".

No. The baud rate is for the physical interface of the module and not
the RFCOMM connection.

Doing a little more investigation, I found a library that sends/receives
data over a socket connection using rfcomm.
However, if I use the client side of this library, doing a connect to
another bluetooth device that implements the Serial Port Profile, it
works beautifully, I'm able to send data that gets displayed on the
windows side hyperterminal.
When I try to run the server side library on the Linux machine, and
attempt to make a connection over the hyperterminal, I get an error
message: "Connection attempt failed because the remote device does not
support the Serial Port Profile".
How do I get a listener on a Linux host to accept serial port profile
connections?

I guess your server side code hasn't added a service on the local sdpd
so the remote doesn't know you do support SPP. You can add a service
on the local sdpd inside your code or you can use sdptool to do it.
All you need is:
# sdptool add --channel=<channel number> SP
