Hi,
 
Sorry for the typing mistake in my previous email.  It should read 
 
memset (readbuff, 0, 100);
 
not 
 
memset (dread, 0, 100);

Hi Marco,

Thanks a lot for your help. I wrote my own program
using rfcomm, and have been able to establish
connections with phones.

I have also been able to write data to phones. 
However, I am currently having trouble reading data
sent from the phone to the board. 

The application running on the phone receives data
from me, displays it, and then echoes it back.

The program I have written is pretty much the same as
the RFCOMM's main.c's cmd_connect function, except now
it receives an argument from the user and sends that
out through a socket once it has connected with a
phone. This part works fine. 

Just after the write function call, I call read as:

chk_read = read (sk, readbuff, 2); 

with sk being the file descriptor of the socket
connected to the phone, readbuff being an array of
type unsigned char and size 100, and reading in only 2
characters. I have earlier initialized readbuff as:

memset (dread, 0, 100);

However, when I send data to the phone and it receives
this data and displays it, once it has sent the data
back to the board, the board does not receive it. 
Rather it waits for data to be received, and once
disconnected displays that chk_read has been assigned
a -1, meaning no data has been read. I have called
the read function for reading more than 2 characters
(have used readbuff's maximum size, 100), but still no
good.

Any idead what's going wrong here? Any help will be
greatly appreciated.

Thanks and sincerely,

Naved
