Robin,
the job is already done for you.  Download kernel 2.6.22 and take a look 
in net/bluetooth - you will see that the source code is there already.  
Run menuconfig and you will see bluetooth configuration options under 
the networking heading.  The fact that you are building for ARM 
shouldn't present any additional problems.

Robin,

once again, the work has been done already.  You really need to study 
the documentation and configure properly.   If you have a bluetooth 
module connected to a UART and it understands one of the supported HCI 
protocols then you don't need to write any kind of driver you just need 
to tell the bluetooth subsystem which UART to talk to, what protocol to 
talk with and the baud rate etc.  Typing 'man hciattach' will explain 
this well enough.  You would also do well to buy a decent book on Bluetooth.

I would advise you to direct further questions to the manufacturer of 
your Bluetooth module.  You will need to know which HCI protocol it 
supports, the baud rate, handshaking etc.

[Bluez-devel] Blocking connect(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM) => EINPROGRESS

[Olivier Le Pogam]

Hi,

I am trying to perform RFCOMM connection to a mobile phone thanks to a 
blocking "connect(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM)" (Blocking is 
the only way for me to get a "Connection Refused" return status !), and if 
the phone is still asking for the authorization when the connect times out, 
the connect and leaves with a EINPROGRESS status.

Could you please tell me :
- If there is a way to extend the blocking "connect" timeout ?
- When a connect exists with a "EINPROGRESS" status, does it make sense to 
try another "connect" on the same socket without doing a complete retry 
(close / socket / bind / connect) ?

Thanks a lot,
Oli

I have no idea what you are trying to achieve here. Anyway, the RFCOMM
socket behaves like every other TCP socket. So in the non-blocking case
apply the same stuff you use when programming TCP.

Regards

Marcel
