I also suspected that so I've powered the module from another power supply (and connected all the grounds).

Still the same result.

I still can't figure is why this only happens with MySensors... Test sketches run ok...

Hi all,

Since this is my first post I would like to congratulate all mysensors community for the fantastic work.

I've been running some prototypes of sensor nodes using standalone ESP8266 as node/gateway with no major problems.
But now, I've ordered some RFM69 modules to start building a sensor network and I'm having trouble getting mysensors to work in a particular combination: Arduino Nano and RFM69HCW (Adafruit 5v safe breakout).

Using test sketches from the RFM69 library everything works fine (on the other end I have an 3.3v arduino pro mini with a RFM69 module) but from mysensors I only get this output:

0;255;3;0;9;MCO:BGN:INIT GW,CP=RRNGA--,VER=2.0.1-beta
0;255;3;0;9;TSM:INIT
0;255;3;0;9;!TSM:INIT:TSP FAIL
0;255;3;0;9;TSM:FAIL:CNT=1
0;255;3;0;9;TSM:FAIL:PDT
0;255;3;0;9;TSM:FAIL:RE-INIT
0;255;3;0;9;TSM:INIT

I've tried to replace the default RFM69 driver with the version from LowPower Labs with no success.

The strange is that the very same code uploaded to an arduino pro mini works fine.

What can it be?
