How to add nrf cloud LTE modem

[Muhammad Usman]

Hi All! 

I am using a hologram NB-IoT sim card in nrf9160DK. And want to connect it /send data to nrf cloud. I have activated the sim from the hologram website. When I tried to add the nrf9160Dk in nrf cloud as an LTE device it gives me a 40412 error.LED # 3 is continuously blinking. I read all the related issues but still fail to add the LTE device. The only issue I assume is about the NB-IOT hologram sim. Is it supported by the nrf9160DK modem?. The country I am using this hardware is Pakistan.

Thanks & Regards,

Muhammad Usman

Hi Muhammad,

nRF9160DK is compatible with the LTE-M/NB-IoT network just like a 5G phone need to connect with a 5G compatible network.

Please try to confirm with Hologram. Cat-M1 and NB-IoT coverage – Hologram

You can also play AT client sample to do a simple connection test with LTE Link Monitor.

Remember to go through the following document first. Getting started with nRF9160 DK — nRF Connect SDK 2.0.0 documentation (nordicsemi.com)

Best regards,

Charlie

Hi @ Charlie!

Thank you for the response! Hologram Support team is saying NB-iot is upported in your region.

I tried your instructions and got the following results. as mentioned in the image .

Led # 1 is continously blinking.

Can you please help me in this regard ?

Thank you!

Hi Muhammad,

Sorry for the late reply.

Looks like the device still has problems contacting with local NB-IoT network.

1) Can you share the full log file by clicking OPEN LOG FILE on the bottom of LTE Link Monitor APP?

2) Can you program the application nrf9160dk_fw_2022-06-02_880c82db\img_app_bl\nrf9160dk_serial_lte_modem_2022-06-02_880c82db.hex and run the following commands? Please remember to enable Automatic requests in SETTINGS of LTE Link Monitor. I expect to see its log file as well.

AT+CFUN=4
AT+CFUN?
AT%XSYSTEMMODE=0,1,0,0
AT+CFUN?
AT+CFUN=1
AT+CEREG?

Best regards,

Charlie

Hi Charlie 

Sorry for the late response! 

I attached the log file after uploading the .hex file you mentioned!

Thank you so much for the response and help!

Hi Muhammad,

I assume you have enabled Automatic requests in SETTINGS of LTE Link Monitor.

Could you run the same commands and then run "AT+CFUN?" at last to trigger the Automatic requests? It should give more information like the following log.
