[Bluez-users] libbluetooth usage

[Jaime Alberto Silva]

Hi everyone!

Can someone please point me to some documentation about libbluetooth usage?

How can I use this library to establish comunication with a BT device?

I'm trying to write a program in J2ME for my Nokia 6670 that
communicates with my Linux PC via RFCOMM. If I use the rfcomm utility
like this:

# rfcomm bind 0 00:02:5B:00:A5:A5

All I have to do is write a program that opens the rfcomm0 serial port
and waits for data? How can I detect when the client connects?

How do I use the RFCOMM socket interface?


Thanks in advance for your attention and any help you can bring me.

The client is the phone, the PC will have an application waiting for
connections from the phone.

who is the client?

The programs rctest.c and attest.c give a good example on how to use the
RFCOMM socket interface.

then you are looking for "rfcomm listen" and not "rfcomm bind".

They are part of bluez-utils source package.
