Data received multiple times #12

Open ksb86 opened 8 years ago

ksb86 commented 8 years ago

I'm getting the data transfer ok by using 'sudo ./codesend 123' on one raspberry pi and 'sudo ./RFSniffer' on another raspberry pi. However, for every time I transmit by using codesend, the sniffer end is receiving anywhere from 1 to 5 responses for each send. Am I missing something? Is this how rf is supposed to work? Thanks.

Since 433mhz radio communication are unreliable, the code are sent multiples times to be sure it is received.

Here is where it is setup in RCSwitch library https://github.com/ninjablocks/433Utils/blob/master/RPi_utils/RCSwitch.cpp#L41

this->setRepeatTransmit(10);

@maditnerd Thanks! That make sense.

I'm guessing this issue can be closed since this is the intended behavior.

Yes, I would say so. Thanks.
