Unable to change APN Thingy91

[Alejandro Chavez]

Hello everyone!

I just got a Thingy: 91 and followed the startup guide, updated the firmware, and installed the modem...

I had trouble using iBasis eSIM because there is no coverage here in Berlin, so I bought one from 1NCE that does have coverage here. I inserted it to Thingy: 91 but I can't find how to configure the 1NCE APN.

Any help for this case?

Hi Alejandro,
Did you try the "thingy91_nbiot_legacy_pco" version of the precompiled application?
Could you share the output log?

You can set APN via the AT command AT%XAPNSTATUS.

Or you can build the Asset_tracker application with the following configurations in prj.conf:

CONFIG_LTE_NETWORK_MODE_NBIOT=y
CONFIG_LTE_LEGACY_PCO_MODE=y
CONFIG_LTE_PDP_CONTEXT="0,\"IPv4v6\",\"iot.1nce.net\""

.

Thanks for your reply!

I'm using "thingy91_nbiot_dfu_2020-04-29_bc7ade8b.hex" version.

This is the output:

[0m<dbg> nrf_cloud_transport.nct_connect: getaddrinfo failed -11

[1;31m<err> asset_tracker: Failed to connect to cloud, error -3

[1;31m<err> asset_tracker: Network error, check cloud configuration

[1;31m<err> asset_tracker: Device will reboot in 300 seconds

[1;31m<err> asset_tracker: LTE link disconnect

Hi Alenjandro,
Please try the "thingy91_nbiot_legacy_pco_dfu" version.

Thanks! It works now!

It's currently working with NB-IOT, but we need to use LTE-M, it's this possible?
