Hi Duoc,

According to Connect to nRF Cloud, you must first provision the device to nRF Cloud, using the UUID from the modem firmware as device ID.

1. Using AT#XUUID to get UUID.

2. Login to nRF Cloud and prvision device with this UUID, see update the nRF Cloud certificate.

Then try again to see if the nRF Cloud connect can be built.

Best regard,

Charlie

Hi. I have a nRF9160 dev kit. I want to use XCELLPOS to know to location.

I use the application firmware nrf9160dk_serial_lte_modem_2023-03-02_8f26142b.hex.

But I always got the error at AT#XNRFCLOUD=1 and AT#XCELLPOS=1

The response is: ERROR

I also attached the log.

Thank you very much.

Hi Stas,

Here is my test log. It seems your device did not detect other neighbour cells. It only shows the cell station you connect with.
