hey
i am currently working on a project where d microcontrollers communicate with each other using RF module(i.e wirelessly).
the problem is if i have more than 2 receivers how to know and decide which receiver must receive the data, for data security.
I can use different addressing, but can u suggest any other way.
pls help.
thanx in advance.

 

Hello,

First you should expanded your explanation,
what you want to transfer??
What security are you talking, Is data security means that no other one can understand your message??

 

Following up on Rritesh's answer, you could encode the messages to different receivers with different keys with each receiver having only its own key.

 

are you trying to encrypt your transmissions?
