Hi
 There could be several problems of you not receiving data, here are a
few I know of:
1. Check if the programming board's switch is set to "off" position,
else it will not receive any data.
2. If you access a null pointer, ex. if you have an array A[3] and u
access A[4], the appln will run as if everything's fine, but you will
not receive any data, even for that matter, if you toggle leds in the
Send, it will be as if everything is correct!
3. In case the TOSH_DATA_LENGTH differs betn the 2 applns, then too
you wil not receive any data.

Hope this helps
