Hello,
I have been trying with various degrees of success to get a pair of RFM69HCW radios to transmit and receive data. After a bit of testing, I was able to get some data. As I continued testing to try to integrate them into my main project, without changing any of the circuitry, they no longer communicate. Since then I’ve just been trying to get everything working again, but to no avail.
The radios are both hooked into my laptop in two different Arduino IDEs and the hookup guide was followed. The only difference between what I have and what the hookup guide shows is that I used just the RFM69HCW, and not the breakout board variant. But it did work all the same. The serial monitor shows the each radio can try to send data, but they’ll immediately just say that no acknowledgement was received. Sometimes they’ll sit and seem to wait for an acknowledgement and just remain there for a while.
Any ideas?
