I recently got a Sodaq Sara R410M that someone tinkered with before me, so I have no idea which settings the preowner made. Unfortunately, I couldn't find anything about a way to get everything back to factory defaults, so it seems like I'll have to figure it out manually?
I'm trying to connect it to the German 1nce.
Here's some information I found helpful:
I tried to follow that guide, but I think I might have messed up something by myself. In order to set the correct band (band 8), I tried setting at+ubandmask=0,8, but then I realized that this wasn't the option I was looking for.
Now, to my problem:
It seems like some settings are messed up. The main issue right now is that "AT+COPS=?" returns "+CME ERROR: operation not allowed". As far as I can tell, that should work.
I don't really know where to start, so any help is appreciated, even if you just point me in the right direction. If you need more information, I'll happily provide it.
