Hello, I have a WP7700 red and I’m Following the getting started tutorial. I reached the point where I’m supposed to run redSensorToCloud in order to connect to the Cloud. However, this didn’t seem to work so I tried “cm data connect” and I figured out that the device didn’t connect because of the missing DNS I checked again and Indeed in the info the two DNS fields are empty(N/A). So I am sure that the sim card I have doesn’t offer DNS. Any idea how can I proceed ?
How about editng the /etc/resolv.conf file?
Actually I Don’t seem to find this file Under etc…
I can see it in WP76 module.
root@swi-mdm9x28:~# cat /etc/resolv.conf

How about “touch /etc/resolv.conf” and restart cm data connect?
As you’ve suggested @JordanZhao.
We do that during our production testing, else the modems can’t establish a data connection.
Hi
which bearer are you using ?
Can you give the response of the following AT commands ?
AT!SELACQ?
AT!SELCIOT?
Hello so when I created the file I put the google dns (8.8.8.8 and 8.8.8.4) within. When I run cm data connect it says that it is connected but I Don’t see anything on the airvantage. Is there a way to see the traffic at the level of the device ?
@fdu here is what I get for these commands:
AT!SELACQ?
!SELACQ:
LTE
LTE-M1
LTE-NB1
GSM
OK
And the second command :
AT!SELCIOT?
current operating mode : 0x06
supported operated modes:
LTE WB: 0x01
LTE M1: 0x02
LTE NB1: 0x04
OK
Sorry @Maroua
I forgot these 2 commands:
AT+CREG=2
AT+CREG?
The aim is to know the current activated beader: LTE-M1 or LTE-NB1
Thanks
Mhh your device seems to be rejected by the network.
Can you check your APN setting in +CGDCONT command ?
So the Following pdp context is the Following:
+CGDCONT: 1,“IP”,“APN”,“0.0.0.0”,0,0,0,0
and the APN is correctly set.
What would make the device rejected by the network ?
Are you sure that APN is the APN related to your SIM card ?
Can you send me the response to “AT+CIMI” command please ?
yes I’m sure about the APN. As for the command it successfully returns the IMSI.
hi @Maroua,
as indicated by fdu, your device is rejected by the network.
usually it means there is a mismatch between the APN allowed by the network and SIM and the one set into the device ( ie at+cgdcont)
can you double check the following:
at!gstatus?
at+cops=?
at+cgdcont?
cm SIM info
cm radio info
cm data info
in order to check every settings .
Best Regards,
