AT+KSRAT=1,1 solved the CSQ problem but I still have issues later down the sequence.
I am now getting and CME ERROR 921 after the AT+KCNXUP command which I have not had before.
My full sequence is as follows
AT
OK
AT+CSQ
+CSQ: 7,99
OK
AT+CEREG?
+CEREG: 0,5
OK
AT+KCNXCFG=1,“GPRS”,“dataconnect.m2m”
OK
AT+CGATT=1
OK
AT+KCNXUP=1
+CME ERROR: 921
As for firmware, does this give you the information ?
