I'm currently working on getting used to the SARA N211 on my NB-IoT Shield. At first it didn;t respond to a lot of AT commands, so I figured the firmware could use an update. After updating some commands work fne now, others are still not working (AT+NSOCR for example). Yet now I'm facing a new issue.
Whenever I try the AT+CFUN=1 command it simply returns ERROR. I see there's a post with a similar issue here:
Yet the cause if this issue was a wrong SIM card. I'm using a Vodafone NB simcard that has worked fine on my R410M, so I'm guessing my sim card is fine?
My current FM-version is: 06.57,A09.06.
Do you have any ideas, because I'm out of them...
