Hi, in the HIlo3G Software Release Notes (Hi3GC,A.001.00), issue BTS_11000088 is listed:
“The command AT+COPS=? answers +CME ERROR: 3”
But it’s never subsequently listed as fixed. Was there a fix? If so, does anyone know in which version of firmware was it fixed?
Thx
Actually, the issue is not with the command. The issue is with the sms reception while you try to fire the command at+Cops=?
Here’s the Log on v1.44:
AT+COPS=? -->Module will return ERR if receive a SMS during the PLMN request.
+CME ERROR: 3
+CMTI: “SM”,4
AT+COPS=?
+COPS: (2,“CMCC”,“CMCC”,“46000”,0),(3,“CHN-CUGSM”,“CU-GSM”,“46001”,0),(3,“CHN-CUGSM”,“CU-GSM”,“46001”,2),(0,1,2,3,4),(0,1,2)
OK
Hope it helps!
Thanks
Alex
