Connectivity - Gateway SIM connection settings
Nov 1, 2021 · 2 minutes to read
This article explains how you can configure your Treon Gateway cellular communication settings.
You can view and adapt the standard cellular connectivity settings of your Treon Gateway by editing the file
/opt/nbiot_connection/modem.cfg using the command line
sudo nano /opt/nbiot_connection/modem.cfg
sudo vi /opt/nbiot_connection/modem.cfg
When you have opened the
modem.cfg file you can view the parameters set and change them.
MODEM_URAT: priority list of cellular technologies used for connectivity
PIN: SIM PIN code
APN: access point name override
ROAMING: defines if cellular roaming is allowed
UMNOPROF: Defines modem network profile, should not be modified unless there are connectivity issues.
The PIN code can be set and enabled by using a helper script in the same folder. Note that usage of the pin code has to be enabled before it is possible to change it. You can do this with the following command:
sudo python ofono_control.py –enable-pin sudo python ofono_control.py –change-pin old_pin new_pi
