nrf9160: LTEM connection in Canada

Hi Aswin,

Just put the configurations:

CONFIG_LTE_PDP_CMD=y
CONFIG_LTE_PDP_CONTEXT="0,\"IP\",\"apnname\""

in your projects prj.conf file for the application that is going to run on your device. It will then select the APN when it turn ON, resets etc.

So if you are able to update the device firmware then this is the solution.

e.g.

If your application can configure the default APN to the Modem then application could as well be able to give it to Modem each time when you create PDN connection.

Unfortunately there is no AT command that can store the APN. It has to be set before you turn on the modem.

Best regards,

Thanks for the response.

We are able to connect to the network after sending

AT+CGDCONT=0,"IP","apnname"

just after the device reboot.

Is it possible to make this configuration persistent?

Because we can not update the device firmware now due to some reasons. Any AT commands for APN persistent storing?

Thanks

Hi Aswin,

To set the APN in a project you can add that configuration in the prj.conf file.

For example:

CONFIG_LTE_PDP_CMD=y
CONFIG_LTE_PDP_CONTEXT="0,\"IP\",\"custom.apn\""

If this is required by Telus when using that SIM card it would most likely be a note about that in their site. (or if you contact them)

For further investigation from our side we would need some serial output log from testing a sample/application on the nrf9160 or even better a modem trace.

Best regards,
