RFM69HW on Arduino not transmitting/receiving
« on: January 25, 2015, 12:24:00 PM »
I am having trouble getting the RFM69HW transceivers send or receive data.
 I have 2 RFM69HW transceivers and 2 Arduinos Unos with the ability to run at 5v or 3.3v. Both Arduinos are set to 3.3v. They are wired as follows:
NSS – D10
MOSI – D11
MISO – D12
SCK – D13
DIO0 – D2
3.3v – 3.3v power on board
I also put a short piece of wire on the ANA connection, but I didn’t connect the other end to anything.

I loaded the sample sketches for the gateway and node, one on to each. I commented out the 433MHz section and uncommented the 915MHz section as mine are 915MHz boards. I also uncommented the section that indicates that it is a RFM69HW.
When I hook the Arduinos up and enable the serial monitor the Node says that it is transmitting, but the gateway does not indicate that it is receiving anything.

Does anyone have any ideas as to where I should be looking?

Yes there are many many posts about UNO + RFM69 in this forum, a "uno rfm69" search will get you a lot of results.
