Issue:RAK7243C gateway. Verifying the LTE connection, it always returns the error below “No network protocol running”.

Setup:I’ve explained it below.

Details:
Hi,

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

  1. First, insert a SIM card. Power on the Gateway.

  2. Then, log into the Gateway through SSH, and enter the command: sudo gateway-config.

  3. 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.

  1. sudo minicom -D /dev/ttyAMA0 -b 115200

  2. “ at ” returns with “ OK ”.

  3. “ at+cops=? ” to look for all available LTE networks

  4. at+cops=1,0,Movistar,7 to set the LTE network operator that you want to use.

  5. 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.

  1. 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.

  1. 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.

  1. How can I know where that “unterminated quote (line 4)” is coming from?

  2. I tried with 3 different vendors/sims. Same error.

could the problem be the line “No auth is possible”? what is it?

  1. 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
