Rain Gauge stopped sending[Solved]

[flopp]

It was working for at least 24 hour then suddenly it stopped.

Hi!

st=fail means radio comm problem. The second row is asking the controller for config, t=6, metric or imperial.

Radio problems are often power related, sometimes it can also be bad piece of hardware.

Check cables/connections.
Try adding 4.7 uF capacitor near radio.
Try adding two caps near radio.
Try a different power source.
Try another piece of radio.
Move node closer or farther away from gateway.

@martinhjelmare

Thanks.

Just before you posted this I Cleared the EEprom and upload sketch again, then it started to work.

[martinhjelmare]

@flopp

OK. Good to hear. Do you think it was a routing problem, between node and gateway?

[flopp]

@martinhjelmare

Yes, because when i test in my house it connects to my Repeater Node, but when I place it where it shall be I don't work anymore. It happened again.

Can you confirm that: If it connects to a repeater node first time you start it it must go through that node everytime?

[sundberg84]

If will self-heal and it takes some time, you need some ST:fails for it to search new parent. When it do that route is stored and next time it will send that route.

[martinhjelmare]

Yes, I think 6 fails are needed, before searching for new route.

[flopp]

Now it works, without Repeater Node. I flipped the bucket a couple of times.

But i wonder why it didn't heal before.

Can it be that when the timer is waking up the Sensor Node it doesn't heal.

Because it has been offline for 12 hour, sleeping 1 hour each time, without healing. No rain had come during this period. Now i was flipping the bucket and it start to heal.

[martinhjelmare]

@flopp

I think it's 6 consecutive fails that's needed before the route search, and from your first log, it seems not all messages were failing.

[flopp]

@martinhjelmare
Yes, that can be the reason.

Thanks everyone
