Unable to ping or query dns

[Agathe Lee]

Hi! I have a MTQ-LVW3-B01. I am using and activating Context #3, successfully receiving an IP address. I am able to make socket connection to a server, however when I try making a connection with a hostname (to be solved by dns query) or pinging an IP address, I receive an error.

Hi Agathe,
I believe the current firmware does not resolve correctly if an IPV6 address is obtained when activating the PDP context. Try disallowing IPV6 using the following command:
AT#SGACT=3,”IP”
Then restart the PDP context and try opening a socket using the hostname of the server.

The command AT#SGACT=3,”IP” returns ERROR. I tried modifying the PDP context with AT+CGDCONT=3,”IP”,”VZWINTERNET”,””,0,0. This also returns ERROR.

Hi Agathe,
Sorry about my last post, +CGDCONT is the correct command (not #SGACT). I’m not sure why you got an ERROR response. Try the following sequence and see if it helps:
AT+CMEE=2
AT+CGDCONT=3,”IP” (note: only send 2 first 2 parameters)

Hi Lonny,

Here’s the result:
at+cmee=2

OK
at+cgdcont=3,”IP”

+CME ERROR: operation not supported

Hi Agathe,
The extended ERROR information doesn’t appear to be of much help. I can’t think of an explanation for the ERROR response, command syntax looks correct. You may want to open a support ticket at http://support.multitech.com
