Dragino LoRa shield with LMIC and 1-Wire sensor problem

[martin_schilliger]

Your support is great, thank you!!

(Beware: in your earlier log, the “Length: 37” line was printed or captured an hour late too, at 20:04:33.070, while the “Send” line was then captured at 19:05:03.489. Adding flush() ensures that the log is always printed right away.)

Ah, that looked crazy for me too, didn’t know that this is the reason, thank you!

@arjanvanb

I wonder if those 3 seconds make it fail to detect some overflow

Could it be the delay() after it, that causes problems? I’ll try to remove it.

@arjanvanb

• Maybe using the recommended OneWire 2 helps?
  […]
• Maybe one can explicitly pause/disable 1-Wire after taking the measurements?

I’ll take a look at this

@arjanvanb

By the way, what is port 13 used for?

Just a red LED

@arjanvanb

You might add trying another LMIC library to your lists of tests.

That was my first try, looking throught all the different LMIC libraries I found. The problem was the same everywhere. But I didn’t try the to look into the sensors. Will do that the next days.

@cslorabox

Additionally the original question here said the time to failure was variable.

I thought that, but it’s not true. It’s working in the right interval for exactly 71min and then it uses a 71min interval. I just haven’t found the regularity before YOU named it.

What’s next

You gave me a bunch of ideas to try, I will do that and come back with new console logs and knowledge. Thank you for the support so far!
I think I need some time to try all of them, but now it’s too late in the evening.

I’ll keep this thread up to date.
