Okay, this looks correct. Just one thing: in your original ticket you say you're working with a DK and mention PCA10090, yet here you're building for the Thingy:91 (pca20035). Is this intentional?

If not, you can find the board folder for the development kit at ncs/zephyr/boards/arm/nrf9160_pca10090.

Best regards,

Heidi

The application is inside the cloned repository from hereas
https://github.com/NordicPlayground/fw-nrfconnect-nrf I cloned the repository by using west as in "Getting Started Assistant" guildline said. I didn't run a "git checkout" to nrf folder yet.

AT client application is here. [Source root]/ncs/nrf/samples/nrf9160/at_client
You can take a look at my project path on SEGGER embedded studio.

Hi, yes it looks like you're using the correct modem firmware version but I'm asking about the application, the AT Client sample. You can find the app firmware here - scroll down to "nRF9160 SiP application and modem firmware". You need to flash this to the chip as well using the programmer application.

I am sure that I have used the firmware from nordic's website (nRF9160DK page). here is where I downloaded it.

https://www.nordicsemi.com/Software-and-tools/Development-Kits/nRF9160-DK/Download

There are no "images_full" directory in the downloaded .zip file. The inside of it looks like this.

When I used nRF Connect - Programmer to update a firmware, It asked only for a .zip file. So, I cannot selected the directory called "images_full" anyway.

Hi!

If you're not seeing the Zephyr boot message after hitting the reset button, try flashing the modem FW and the application again.

Are you sure you used the correct file when flashing the application? If you're downloading the firmware from our website, make sure to use the files in the directory called "images_full".

Best regards,

Heidi
