hi,
probably my english won't be good..but my problem is:
2 modules with microcontroller+sensor+transceiver...
the only problem I've is...
send an encypted data from a module o the other via radio (wireless) end decrypt it when it'll come..if it'll come!!
have you some suggestions about (I must use C programming language to implement the communtication).
if you have some sites with examples or other..
I'm new in this kind of field.
thanks
Daniele
