Using an interrupt and LoRaWAN

Can you see why we're frustrated?

Dribbling out (or not) information about your problem is a waste of time, not least yours, when you have to wait five minutes between posts.

You could have told us in your first post which processor you're using, what type of interrupt, what your code looked like (passwords etc are very easily masked/redacted).

Instead, we got waffle.
