The nRF52 DK is a versatile development kit for Bluetooth Low Energy, Bluetooth mesh, NFC, ANT, and 2.4 GHz proprietary development on the nRF52832 SoCs.

Objective: Compile, build, and test a basic example using the nRF App.

Steps:

• nRF52 DK hardware setup
• Compile and build an existing example
• Test using nRF App

Install Visual Studio Code here
Install nRF Connect here
Download nRF5 SDK here

Blinky Led

• Duplicate the Blinky LED:navigate to the Blinky LED example in the downloaded nRF SDK folder.
  C:\Users\...\nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_blinky
  Duplicate the "ble_app_blinky" folder into a new folder named "test."
• Navigate to C:\Users...\nRF5_SDK_17.1.0_ddde560\components\softdevice\s132\hex
  and duplicate the file s132_nrf52_7.2.0_softdevice.hex into a folder named "test."

Visual Studio

• Launch Visual Studio and import the "ble_app_blinky" folder.
• Make simple modifications such as changing "Nordic_Blinky" to "Nordic_Blinky_HelloWorld."

Compile and build

• Initiate the terminal and command line:
  C:\Users\....\examples\test\ble_app_blinky> ls
  C:\Users\....\examples\test\ble_app_blinky> cd .\pca10040
  C:\Users\....\examples\test\ble_app_blinky\pca10040> ls
  C:\Users\....\examples\test\ble_app_blinky\pca10040> cd .\s132
  C:\Users\....\examples\test\ble_app_blinky\pca10040\s132> ls
  C:\Users\....\examples\test\ble_app_blinky\pca10040\s132> cd .\armgcc
  C:\Users\....\examples\test\ble_app_blinky\pca10040\s132\armgcc> ls
  C:\Users\....\examples\test\ble_app_blinky\pca10040\s132\armgcc> cd .\_build
  C:\Users\....\examples\test\ble_app_blinky\pca10040\s132\armgcc\_build> ls
  

Programming the nRF52 SDK

• Start nRF Connect
  
• Launch nRF Programmer by clicking on "Open."
  
• Programming the firmware ->Add file->Browse.. Navigate to to examples\test\ble_app_blinky\pca10040\s132\armgcc\_build
  and select: nrf52832_xxaa.hex
  
• Programming softdevice ->Add file->Browse.. Navigate to examples\test
  and select: s132_nrf52_7.2.0_softdevice.hex
  
• Select the nRF52 SDK ->arrow up-> and select the connected nRF52 SDK on the PCB through USB.
  
• Click "Erase & Write"
  

Final Test

• Launch the nRF App on your smartphone; you should observe the name "Nordic_Blinky_HelloWorld." Connect to it.
• Perform tests, such as pressing button 1 on the nRF52 SDK; you should observe the corresponding action in your app.
