Issue:RAK7243C gateway. Verifying the LTE connection, it always returns the error below “No network protocol running”.
Setup:I’ve explained it below.
Details:
Since I received the RAK7243C gateway it has been working with my home WIFI without problems. It works perfect.
Now I am configuring it to work over LTE since it is very possible that I will end up putting it in the countryside, with power, but without Internet. That is because I need this setup.
I have followed the steps in the Rak documentation manual.
https://doc.rakwireless.com/rak7243c-lorawan-developer-gateway/accessing-the-internet
First, insert a SIM card. Power on the Gateway.
Then, log into the Gateway through SSH, and enter the command: sudo gateway-config.
Choose “ 7 Configure LTE Module ” and complete the process back and forth as you explain in the guide.
Enable LTE Automatic Dial-up - the default option and is used to enable automatic connection during start-up.
Disable LTE Automatic Dial-up - used to disable automatic connection during start-up.
sudo minicom -D /dev/ttyAMA0 -b 115200
“ at ” returns with “ OK ”.
“ at+cops=? ” to look for all available LTE networks
at+cops=1,0,Movistar,7 to set the LTE network operator that you want to use.
Setting the APN name . I have put 2 different sims (APN= movistar.es and the other APN=tuenti.com ). I’ve tested both sims in a cellular, without PIN required, and browsing Internet perfectly.
And baud rate.
Verify the connection: sudo pppd call gprs
But I must be doing something wrong because when verifying the connection, it always returns the error below “No network protocol running”. See bellow screenshot.
And I can see that I don’t have an IP assigned: at+cgpaddr returns ERROR
Thanks,
Manuel

It might be worth trying to see where that “unterminated quote (line 4)” is coming from.
It could be an irrelevant typo in a static configuration file that doesn’t actually matter.
But if there’s any chance it’s a result of how you entered the custom settings for your provider, that might explain the issue.

Hi,
Appreciate your quick answer, I have some doubts.
How can I know where that “unterminated quote (line 4)” is coming from?
I tried with 3 different vendors/sims. Same error.
could the problem be the line “No auth is possible”? what is it?
There is 4 possibilities to put the SIM card in the slot. Do you have an image with the correct position of the sim in the slot?
Many thanks,
Manuel

I bought it in Madrid. And yes it is a rak7243c.
Hi, I’ve that problem too. I tryed a lot of things.
update firmware (download: 2022-06-24)
setup the PIN for the sim card in the script: /etc/chatscripts/quectel-chat-connect
I updated the APN (provider is telekom, so I used: internet.telekom)
following log:
I tryed about weeks and have no ideas anymore. Thanks a lot!
Seems after reboot all is working fine. Not sure, but I got no error.
