Hi, this is my first time posting something like this, so feel free to correct me if I’m doing something wrong. I have a standard Flipper zero and 2 RFM69HCW arduino radios. I am able to have the two radio’s communicate to each other, but if I try to take my flipper and copy the transmitters code and then replay it, the reciver doesn’t activate.
To do into more detail, I am using a 915 frequency radio, and the raw mode of the flipper. I can see that the flipper detects the signal in the little screen as a line spikes, but when I try to replay it, nothing happens. It shows the spike on the AM270 and AM650 modulation setting and nothing else. I can post the code to the arduino if that helps. Thank you in advance!

It’s possible the communication is two way. To further diagnose your issue we would need to know what protocol you’re using. Depending on the protocol you might see something like the following if it were in English rather then binary.
“Can you hear me?”
“Yes I can hear you.”
“Here is some data.”
“I got the data.”
“What’s the check value?”
“The check value is 23.”
“That’s it. TTFN.”
Lets say you want to have the EXACT same conversation. When you play back the data the timing is all off and you are potentially speaking for both sides. Sometimes when the receiver starts you interrupt it or maybe you never even stop transmitting long enough for the receiver to reply.
