Hi,
I have been really pleased with my GSM1400 until today. It has been running sending data to the cloud every hour, on test, for quite a few weeks. Today it suddenly stopped connecting to the GSM network and I cannot get it to reconnect. I have debugged using the GSM test and this comes out:

Connecting GSM network...AT

OK
AT+IPR=921600

OK
AT

OK
AT+UPSV=3

OK
ERROR

Similarly for GPRS ping

AT

OK
AT+IPR=921600

OK
AT

OK
AT+UPSV=3

OK
Not connected

As I said before, tt was running quite happily and then suddenly stopped. The board is running happily without connecting to GSM. I have changed aerial, and changed sim card. Nothing works. Hair is being pulled out!!

Anyone seen similar? Anyone fixed it? Any ideas??

Don't want to spend another £50+ to buy a new one if it's a quick fix.

Thanks in advance

Work this one out!

Used online editor and it started working. Using arduino app. does not work. Think there's a bug in the arduino app library???

I have the same problem. Tried the online editor just now... Same problem. What sketch did you run on the online editor?
