Hi,
I am trying to upload data from two sensors, the BME280 and APDS9960, to the nRF Cloud. I have been able to extract data from the sensors with I2C, but it seems I am getting an error when trying to connect to the nRF Cloud. It is regarding the funcion `lte_lc_init_and_connect'.
I am coding on VSCode with the latest extension, v2.9.0 on Windows 10. I am still a novice with this, so any help would be appreciated.
I am attaching photos of my code and errors.
Hi,
Which device do you use?
Do you use any of our samples as basis for your application and for your testing?
Can you show your build command and provide complete build log? You could upload your build log by first making zip file and then clicking on Insert -> Image/video/file -> Upload.
Best regards,
Dejan
It seems I forgot to mention that it is the nRF9161DK. My bad.
My build configuration is the following.
Build Command:
west build --build-dir --pristine --board nrf9161dk/nrf9161/ns -- -DNCS_TOOLCHAIN_VERSION=NONE -DBOARD_ROOT=c:\Users\RS_G\workspace\cloud-test
Build LOG:
Hi,
You can start by looking at Getting Started with nRF Cloud and then you can look at cellular samples in the documentation.
Best regards,
Dejan
Hi.
I have been working on the code for a while and was reading documentation on the CONFIG_NRF_CLOUD or nRF Cloud API as a way to send my data to the cloud. However, I noticed that the library does not appear for me and saying 'undefined symbol'. I am not sure why the SDK does not see the library. I am on the latest toolchain v2.9.1.
If I remove the config and let the code run, I am returned an error. I have tried checking ID, and updating to no avail.

Hi Ryan,
Which application sample did you use as basis for your application?
Regarding inability to use CONFIG_NRF_CLOUD, I can see that this option is not used in NCS v2.9.0 (in nRF Cloud multi service sample) but it is used in main. Can you try to use main instead of NCS v2.9.0? What is the result?
Best regards,
Dejan
Hi, I based this code off the nrf_cloud_rest_device_message and the nrf_cloud_multi_service codes. I changed to main and now the CONFIG works, however I still have the same error without changing the code. So it was not the CONFIG but possible credential issue.
