I am attempting to move data across a bluetooth connection using
RFCOMM = sockets in C.

I am able to establish the connection and I can succes= sfully send and

= first four characters.

I have tried several things to make this work= , first was to send the
message size initially and then break the messag= e up into pieces no
bigger than 4 bytes and send them individually.  The sending = program
again reports a complete success and the receiving program gets = the
correct message size and only the first four bytes of the message.
The next step I tried was to have each side close the socket after
each = transmission and open a new socket for each data chunk.  This led=
to the same results as before.

I am at a loss about what I am do= ing wrong after searching the web for
information on bluetooth socket programming.  Has Anyone seen= this
sort of problem before and if so what did you do to fix it? &= nbsp;Thanks
for your help.
