Thanks for ur answers
for my project, I send 8 bits of data as the ID for each device to be active.
For example, when the push button 1 is pressed, 8 bits data, ie "0b00110011" will be sent by the transmitter and received by the receiver containing the same ID and the device will be ON. I have tried to send 2 different data for 2 receivers containing a different IDs using the 1 transmitter only .It works! Unfortunately, it contains noise.
From your explanation, I've got to filter incoming data to the receiver rite? Meaning, the data received by the receiver will be managed by using the CRC technique before it activated the device.
Correct me if I'm wrong..
