Tutorial - RFM69HCW Hookup Guide
Hi, Is it possible to stop the led on the Arduino to blink at every radio.send(TONODEID, sendbuffer, sendlength) call?
I have removed the pin definition for the led and all the calls to the Blink function, but nothing changes.
Hi, I am using a Pro mini connected to a normal FTDI board for serial logging while the RFM69 break out board is powered separately by a voltage regulator I have built, but it does not work: the Arduino still needs external power. Can you help me to understand why? Thanks!
EDIT: I think I found the problem: SPI protocol needs a common ground. Just tried and now it is working perfectly!
