Hi,
I’m trying to use the module with a 2G SIM that was working before, but now after getting a valid IP and trying the ping command I get the following response:
+QPING: 561 (Open PDP context failed)
The sequence of commands is as follows:
AT+CFUN=4
OK
AT+QCFG=“nwscanmode”,1
OK
AT+QCFG=“nwscanseq”,01
OK
AT+CGDCONT= 1,“IP”,“my-APN”,“0.0.0.0”,0,0
OK
AT+CFUN=1
OK
AT+COPS=1,2,“my-OPER”,0
OK
AT+CREG?
+CREG: 0,1
OK
AT+CGACT=1,1
OK
AT+CGPADDR=1
+CGPADDR: 1,10.2.184.45
AT+QPING=1,"www.google.com.uy"
OK
+QPING: 561
AT+CGDCONT?
+CGDCONT: 1,“IP”,“my-APN”,“0.0.0.0”,0,0,0
OK
I used the same SIM with a BG96 and it’s working fine, any tips on what might be the issue?
Best regards,
Edu
