The following instructions will help you to change your Tektelic Kona Micro gateway APN (Access Point Name) for T-Mobile and multi-carrier SIMs such as Twilio, Teal, Hologram, etc.
Note: If using AT&T or Verizon SIM cards, these instructions will not work. The gateway will need to be updated with the correct firmware version first.
Step 1
Connect gateway to ethernet.
Locate the gateway’s IP address (you can use an IP scanner).
Get gateway’s password, which is the serial number on the sticker on the bottom of the gateway.
SSH into gateway using a command line interface program like Terminal on Mac or Command Prompt on PC:
ssh root@192.168.2.xxx
Password is the gateway serial number.
Enter following commands to check the system version, current firmware, current APN, and Chirpstack version:
system_version konaLTEmodem.py -c "at!gobiimpref?" konaLTEmodem.py -c "AT+CGDCONT?"
Output will look like this:
Step 2
Enter the following command to change the APN.
konaLTEmodem.py -c 'at+cgdcont=1,"IP","DESIRED APN HERE","0.0.0.0",0,0'
The following example shows us changing our APN to “hologram”:
Step 3
Enter the following command to reset the gateway and apply the changes:
