🤓 Xiao Expansion LBS from Nordic_LBS and Mobile app nRF_Blinky

[PJ_Glasso]

Hi there,

Some are familiar with the Basic Blinky Sketch a similar one exists for BLE , nRF_Blinky is the app from Nordic others exists… I created a Build with the NCS (nRF_connect_SDK) an chose the target as the nRf52840_DK board. (first video) after I flashed it to the dev board and it works. I create a NEW build for the Xiao_nRF52840_BLE board as the target. same code different target is all. After it builds, I can just drag and drop the Uf2 file the build creates to the Xiao in BootLoader mode open as a drive. after a few seconds I see the LED flashing like it’s advertising as the Demo does.
I open Nrf_connect _BLE tool and scan I see the DK and the Xiao advertising the LBS. Nice
they both show up in the phone app… too!
At this point I had to go back and ADD the button to the device tree file map. and another build and BoB’s your uncle. Man this SDK is powerful.

Sweet it can be two ways , add it to the device tree or create an overlay for the whole Xiao Expansion board.

The key to NCS, Zephyr and even Linux peripherals

Once you grasp the concept of Device tree files, Kconfig & overlays. The world is your oyster.
Free , lessons and tutorials, webinars and Very well documented.
The Nordic Semi Youtube videos will take you step by step through this tech and the King of the SDK’s

You can make a build environment for a custom board like a Xiao and it will build Uf2 files Straight away.
makes it easy…Drag & Drop!
