Could it be here? : static void radio_send_data(unsigned long data) { radio.stopListening(car_addr_bytes); delay(5); Serial.print("sending 0x"); Serial.println(data, HEX); bool report = radio.write(data, PAYLOAD_SIZE); delay(5); radio.startListening(); } The write() method expects a …

I certainly won't reject it out of hand. A refactor should be easy (tonight after work). The reason I'm not enthusiastic is because this part has been there from the beginning. I had it working with the unsigned long just fine 2 days ago... before I messed it all up *sigh. I'll definitely see what I…

We have a saying for these kinds of problems: KISS. I suspect the problem is in a totally different place than what you think.

The OP has not returned but, from looking at the code Github repository GitHub - DimoniumAnonimo/Garage-Door-Remote mentioned in post #1, he has solved this by using the address of a variable instead of its value as was suggested to him: [image]
