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
root@swi-mdm9x28:~# cm data
PDP Type: IPV4V6
root@swi-mdm9x28:~# cm info

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.
which bearer are you using ?
Can you give the response of the following AT commands ?
Hello so when I created the file I put the google dns (220.127.116.11 and 18.104.22.168) 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:
And the second command :
current operating mode : 0x06
supported operated modes:
LTE WB: 0x01
LTE M1: 0x02
LTE NB1: 0x04
I forgot these 2 commands:
The aim is to know the current activated beader: LTE-M1 or LTE-NB1
Thank you for your quick comment @fdu
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:
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.
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:
cm SIM info
cm radio info
cm data info
in order to check every settings .
