<![CDATA[Corrupted serial debug output]]>Hi,

I'm building my first MySensors serial gateway on pro mini (ATmega328 3.3V) controller. As a serial adapter I've got PL2303HX adapter connected to arduino.

My test scetches are successfully apploaded to arduino and I also tested serial output via serial monitor of arduino IDE.

But when I get NRF24L01+ connected and serial scetch uploaded to the board I've got some corrupted/binary output to my serial monitor. It looks like screenshot I've attached.

Could somebody direct me to the ways I can debug the issus?

Could you try to re-upload the screen shot? Seems like the forum messed it up.
