This article will outline how to change the APN on the Tektelic Outdoor Micro Gateway

Step 1

SSH into the gateway with root and gateway serial number as the credentials (or via the remote access server):

If you are remotely SSH’ing into the gateway and encounter the following error, SSH into the gateway again to bypass the error and log in:

Successful login:

Step 2

Run the following commands to verify that the gateway has the latest BSP version (1.1.6), the appropriate firmware, and query the current APN:

system_version
konaLTEmodem.py -c 'at!gobiimpref?'
konaLTEmodem.py -c "AT+CGDCONT?"

Verify that the gateway has the latest version of the Chirpstack Gateway Bridge and DPS installed:

/opt/chirpstack-gateway-bridge/chirpstack-gateway-bridge version
/opt/mydevices/dps-client -v

If the Chirpstack version is not at least 3.13.3-r1 and DPS at least 1.3.1-r0, update them before proceeding.

Step 3

If using a T-Mobile SIM card, the APN string needs to be blank. Remove any entries as follows:

konaLTEmodem.py -c 'at+cgdcont=1'

CD into the connection manager file:

cd /opt/connection-manager-db/
ls
cat profile-list.txt

If you see any entries after running cat profile-list.txt, the file needs to be deleted

Run the following commands to delete the profile files and reset the gateway

rm profile-list.txt working-apn-profile-index
sync
tektelic_reset

Step 4

SSH into the gateway again and verify that the APN change is still in effect:

konaLTEmodem.py -c "AT+CGDCONT?"
