[Bluez-devel] (Newbie) Echo server and transferring raw data

[john smith]

Hi there,

I'm pretty new to Bluez and network programming and I'd appreciate if I 
anybody could give me some pointers on passing raw data between two hosts.

I've been playing about with hcitools and l2ping and I've got a pand 
connection happening between two pc's.

As an exercise I'd just like to send some data between the server and client 
and maybe build up my own simple application protocol.

My question is ( and I applogise if this sounds dumb), is there an easy way 
to do this? I've been looking at the l2ping code and I'm thinking about 
experimenting with this. Or is it possible to take an Echo program written 
to use IP sockets and simply substitute in things like 'socket(PF_BLUETOOTH, 
SOCK_RAW, BTPROTO_L2CAP)'  where appropriate.

I've been browsing the Howto's but I've only found info on comms between 
mobile phone's, or sharing internet connections.

thanks for reading,

John

take a look at the source code of l2test and rctest. If you want to port
a TCP application then use RFCOMM as layer, because you will need a
stream socket.
