AT Client Sample
Important: these instructions are outdated and no longer apply for NCS > v1.5.x.
Note: you can get a pre-build binary file compiled using v1.3.2 here.
Change directories to
ncs/nrf/samples/nrf9160/at_client. Then compile as shown beffore in the example code section of this guide.
Before you do compile make sure that the following lines are added to the
# Enable Zephyr application to be booted by MCUboot CONFIG_BOOTLOADER_MCUBOOT=y
This will enable support for the bootloader. Then, build using the build command:
west build -b circuitdojo_feather_nrf9160ns ... -- Configuring done -- Generating done -- Build files have been written to: /Users/jaredwolff/Git/nrf-connect/ncs/nrf/samples/nrf9160/at_client/build [0/180] Performing build step for 'spm_subimage' [151/155] Linking C executable zephyr/zephyr_prebuilt.elf Memory region Used Size Region Size %age Used FLASH: 32256 B 48 KB 65.62% SRAM: 5488 B 64 KB 8.37% IDT_LIST: 40 B 2 KB 1.95% [155/155] Linking C executable zephyr/zephyr.elf [2/176] Performing build step for 'mcuboot_subimage' [248/253] Linking C executable zephyr/zephyr_prebuilt.elf Memory region Used Size Region Size %age Used FLASH: 42500 B 48 KB 86.47% SRAM: 26800 B 64 KB 40.89% IDT_LIST: 72 B 2 KB 3.52% [253/253] Linking C executable zephyr/zephyr.elf [163/176] Linking C executable zephyr/zephyr_prebuilt.elf Memory region Used Size Region Size %age Used FLASH: 76868 B 441856 B 17.40% SRAM: 36928 B 128 KB 28.17% IDT_LIST: 120 B 2 KB 5.86% [174/174] Generating zephyr/merged.hex
Note: having trouble building? Make sure you check out the troubleshooting page.
You can see towards the end of this output that both the application and the bootloader have been built and merged.
Programming can be completed with
newtmgr -c serial image upload build/zephyr/app_update.bin
During testing, it's recomended to use the LTE Link Monitor whenever you need to manually test or execute commands.
