Troubleshooting Kona Gateway Cellular Backhaul

If you are having issues getting your Kona Gateway to connect to your SIM card's cellular provider, please see below for our general troubleshooting recommendations: 

  • For starters, please check the following before moving onto the next troubleshooting steps:

    • Has the SIM Card been inserted into the gateway?
    • Is the SIM Card you have installed "Active" and being provided service by your Cellular provider? Please check with your cellular provider to ensure the SIM card has service.
    • Does your SIM card require any additional firmware to be installed? (i.e Verizon, AT&T)
    • Is your gateway located in a place with good Cellular coverage? 

  • Has the APN for the SIM card been correctly entered? You can check this by running the following command from the gateway command line:

    • konaLTEmodem.py -c 'at+cgdcont?'

If correctly entered, the gateways should respond as seen below:

konaLTEmodem.py -c 'at+cgdcont?'
at+cgdcont?
+CGDCONT: 1,"IP"," NAMEOFSIMCARDAPN","0.0.0.0",0,0,0,0
 
OK

  • Is the Kona Gateway able to detect and read the SIM card installed? You can check this by running the following command from the gateway command line:

    • konaLTEmodem.py -c 'at+iccid'

If successful, you should see the following response from the gateway

konaLTEmodem.py -c 'at+iccid'
at+iccid
ICCID: (CCID of SIM card installed in the gateway)
 
OK

  • If your gateway cellular is still having issues despite having the correct APN and the SIM card is readable, please try running the following commands:

root@kona-micro:~# konaLTEmodem.py -c  'at!entercnd="A710"'

root@kona-micro:~# konaLTEmodem.py -c  'AT!USBCOMP=1,1,10D'

root@kona-micro:~# konaLTEmodem.py -c  'at!custom="UIM2ENABLE",1'

Once these commands have been run, please power cycle the unit.

If successful, the expected output for the above commands are:

  • root@kona-micro:~# konaLTEmodem.py -c  'at!entercnd="A710"'
    at!entercnd="A710"
    OK
  • root@kona-micro:~# konaLTEmodem.py -c  'AT!USBCOMP?'
    AT!USBCOMP?
    Config Index: 1
    Config Type:  1 (Generic)
    Interface bitmask: 0000010D (diag,nmea,modem,rmnet0)
    OK
  • root@kona-micro:~# konaLTEmodem.py -c  'AT!custom?'
    AT!custom?
    !CUSTOM:
                 GPSENABLE          0x01
