Hi there,
I have an RFM69 connected to my Uno (using connection list from several threads from this forum thanks!) and I have the communication working between Node setup on a moteino and the Uno. I'm using the Node and Gateway examples fyi.
My issue: The Uno is getting 3 times the same message (shows up as receiving 3 packets I suppose since the packetCount is incremented at each radio.receiveDone)
Anyone seen something like this before?
I'm thinking:
1- I fried the RFM69 when playing with it and connecting it directly to the 5V (but somehow it kinda works)
2- my soldering skills (or lack thereof) created some bad connections when soldering the cables (but why would it work at all)
3- I did not do setup the voltage dividers on MOSI, SCK and CS correctly (I'm using the 3.7K and 10K resistors fyi as described here
https://lowpowerlab.com/forum/index.php?action=dlattach;topic=744.0;attach=349Miso does not have any voltage dividers and the RFM69 gets power from the 3.3 of the arduino and the rest is connected to the 5V (to get the amps necessary for the radio) - note as well that radio.write does not seem to send anything (ACK is never received by the arduino)
Any suggestions? I ordered another RFM69 from lowpowerlab so I suppose I'll try again in case I fried the board but let me know if anyone have any thoughts/suggestions...

fyi output from serial: (ACK sent is printed but the the moteino never receives it - when using another moteino as gateway everything works fine)
