Arduino Mega Node not working anymore
I have an arduino mega used for automated irrigation after a year of service the node is not responding anymore.
The node runs on mysensor 2.1.1
The serial monitor shows the following

after MCO:BGN:STP nothing happens
what does MCO:BGN:STP mean?

@patrick-schaerer https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ has information on how to interpret the log messages and a link to the log parser which will help you interpret them.

There are a lot of st=NACK messages which means that radio communication from the node to the gateway has trouble. This is usually a power or range issue. See the link above for flowcharts on how to troubleshoot.

thank you for the link

18743 MCO:PIM:NODE REG=1	Registration response received, registration status 1
18746 MCO:BGN:STP	Callback setup()

What is Registration status 1?
Does Callback setup() reinitialize the node?

[patrick schaerer]

I found the problem ...
due to a defective sensor (light meter) the arduino could not initialize correctly.
I think that is why it was calling back setup()
