Hi Charlie,

Thank you so much for the support! yes, that could be an issue with the services in my area. I am trying from the last 1 month and I never connected before!

You can close the issue.

Thanks & Regards,

Hi Muhammad,

+CESQ: 99,99,255,255,255,255

+CEREG: 5,4

The above information shows it does not detect any cell station signal, so it is a high chance there is no NB-IoT coverage in your area.

When did you do the last connection? Is this the same place you do the test now? Can you check with your network operator the current NB-IoT coverage state in your area?

Unfortunately, there are limited things we can do from the device side by far.

Best regards,

Charlie

Hi Charlie!

Thank you for the response! I tried for almost 20-30 mins and I got the following response!

devzone.nordicsemi.com/.../2022_2D00_08_2D00_17T09_5F00_59_5F00_25.903Z_2D00_log.txt

Can you please help me in this regard?

Hi Charlie!

Thank you for the response! I will check again with different SIM cards as well and wait for 10 mins at least to confirm it. I will update you soon on this!

Thank You!

Hi Muhammad,

What I want to check is "+CEREG:" response. The <stat> parameter is 0 which means "0 – Not registered. User Equipment (UE) is not currently searching for an operator to register to.".

It normally takes several minutes(less than 10) for the first connection. How long have you waited by far on your tests? Did you find any change in this parameter? It should be 1 or 5 if the device successfully connects to a local cell station. You will at least get other value if something wrong happens.

Best regards,

Charlie

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.

Hi Charlie

Sorry for the late response!

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

devzone.nordicsemi.com/.../2022_2D00_08_2D00_16T10_5F00_47_5F00_11.746Z_2D00_log.txt

I am using Hologram NB-IOT sim

Thank you so much for the response and help!

Best regards,

Muhammad Usman

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!

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,

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
