I’m trying to get two Arduino boards connected to two RFM69HCW radios to both transmit and receiver to and from each other. I’ve been working this sparkfun/RFM69HCW_Breakout example, https://github.com/sparkfun/RFM69HCW_Br … xample.ino which is described on this sparkfun page https://learn.sparkfun.com/tutorials/rf … ample-code
One Arduino is the Mega2560 and the other is a Pro Mini. I have gotten both boards and radios to communicate with each other, with one pair serving as a transmitter and the other as a receiver. However, when I run the SFE_RFM69HCW_example, both boards appear to transmit okay, but the message is not received by the other board and radio
The sketch seems to run alright up until this line: radio.send(TONODEID, sendbuffer, sendlength); and then it stops. The receiving radio shows nothing received and it’s impossible to try to send any more text unless the Mega2560 is reset. I’ve checked the receiving Node ID which TONODEID should contain and that’s correct.
Does anyone have suggestions for troubleshooting this?
