Issue:RAK7243C gateway. Verifying the LTE connection, it always returns the error below “No network protocol running”.
Setup:I’ve explained it below.
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.
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,7to 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
