      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
                     GPSSEL             0x01
                     IPV6ENABLE         0x01
                     UIM2ENABLE         0x01
                     SIMLPM             0x01
                     USBSERIALENABLE    0x01
                     FASTENUMEN         0x01
                     SINGLEAPNSWITCH    0x01
        OK
