Hi
I'm programming a remote relay controller using PIC.
Pic sends serial (rs232) data trough wireless 433MHZ or 868MHZ.
Transmitter sends some code bytes and receiver gets on serial receiver and decode those bytes.
I use a lot of different codes so that receiver can only be swithced on by its own transmitter. receiver stops working in the moment it doesn't receive data from its own transmitter. Transmitter doesn't send a stop code(i think it's more secure).
The problem is that in that way i can't use 2 or more devices couple at the same time in the same place.
Can you suggest me a way to use them at the same time?
Thanks a lot
