Hello,

I'm new to using Bluez. I need to create a si= mple program to send text over a specific type of port (SOCK_DGRAM, BTPROTO= _L2CAP). The code compiles fine, but when I run it i get the following erro= r (from then sendto function).

Send Failed: Invalid argument<= /P>

What might the problem be? My code is shown below. Thank-you = so much for any help that you can offer.
