ASSET TRACKING v2 on thnigy91

[Suneelmb]

I have been working on asset tracking v2 application code with thingy91 board, as it is not working. I have updated the modem firmware with latest one (thingy91_mfw-1.3.7_sdk-2.8.0.zip), and I am using 2.8.0 sdk and toolchain. As I am using it india where LTE-M s not available,i have added below lines to prj.conf file

CONFIG_LTE_LINK_CONTROL=y

CONFIG_LTE_NETWORK_MODE_LTE_M=n

CONFIG_LTE_NETWORK_MODE_NBIOT=y
As the documentation says no updates needed on configuration as by default set for nrf Cloud I am getting below logs on the screen

Reference: Application description

• nRF Cloud - Connecting your device to nRF Cloud. The default configuration of the firmware is to communicate with nRF Cloud using the factory-provisioned certificates on nRF91 Series DKs, Thingy:91, and Thingy:91 X. This means that no additional configuration of the firmware is needed to connect to nRF Cloud. It is recommended to build and run the firmware on the device before completing the steps listed in Connecting your device to nRF Cloud. See Building and running.

Hi,

 

Could you share the full log?

Your current does not show any information on the initial LTE link setup.

 

Alternatively, you can flash the at_client, which is available in a precompiled .hex here:

https://www.nordicsemi.com/Products/Development-hardware/Nordic-Thingy-91/Download?lang=en#infotabs

 

And issue the AT commands manually:

AT%XSYSTEMMODE=0,1,1,0
AT+CEREG=5
AT+CNEC=24
AT+CMEE=1
AT%CESQ=1
AT+CFUN=1

 

Kind regards,

Håkon

Thanks for the response....I am able to see the data from thingy91. I have 2 sim cards both are active and having validity but one of them is working fine and the other one is not working with thingy91.

Does this mean that you got things working as expected? What does the log state?

 

Kind regards,
