[Bluez-users] tcp/ip with bluetooth

[Manjunath Prabhu]

hi all,
i have a tcp/ip client-server program (i.e) the server is listening
and the client sends information.....right now I am communicating over
the wired network. I want them to communicate over bluetooth.
Is this done by enabling ppp over rfcomm?? if yes, then what am i
suppossed to install???? some rfcomm package..
What about using the bluez-pan package???

hope someone can help me out..

regards,
manjunath

you can establish a TCP/IP connection with the PAN profile or LAN access
using PPP, but you can also change your program to use the RFCOMM socket
instead of the TCP socket.

Use the latest kernel and the latest bluez-libs and bluez-utils and
everything will be there.

hi marcel and co,
thanx for the reply. Its a big big help.

I got the Pan up and running and am just thinking of a way to measure
the bluetooth data transfer rate.........how do i do it????

I was also trying to bring up the rfcomm socket....but am facing some problem...
1. 'sdptool browse bd_addr' shows 'SDP Server' and 'Public Browse
Group Root', 'LAP' but no other services????I was looking for dial-up
networking.......how do i add new services??

2. i run the 'rfcomm bind' command and then try 'rfcomm connect' and i
get an error 'Can't connect RFCOMM socket: Resource temporarily
unavailable'. I read in one of  the mails where you have said that
bind and connect, both  are not required?? Hope u can again help me
with this....

regards,
manjunath

write the profile implementation.

What you are searching for is "rfcomm listen ...", but this was not what
I meant with replacing TCP with RFCOMM. If you want TCP/IP then you can
use pand or dund for doing all the work, but you can also use the RFCOMM
socket directly like you use a TCP socket.

Marcel
