1、 Bare metal serial port verification

Use project path

F:\Module\NRF51822\nRF5_SDK_12.3.0_d7731ad\examples\peripheral\uart\pca10028\blank\arm5_no_packs

1.1、 Engineering setup ：

Code pca10028 Corresponding nrf51422_xxac, The project is revised to

nRF51822_xxAC.

1.2 Download configuration

choice The following chip addresses are configured

Serial port IO The oral test can be flexibly configured into all GPIO, If you do not use flow control, remember to disable  APP_UART_FLOW_CONTROL_DISABLED

After downloading successfully , You can print the log normally .

2、 Project description

2.1、NRF Download tool

nRF Connect for Desktop - nordicsemi.com

2.2、 Protocol stack version

Select according to the routine , If the project does not contain a protocol stack , You need to add the protocol stack file to the above tool separately .

 2.3、 Hardware platform version

stay example in , There are many engineering options ,pcaxxxxx Represents different test development versions .

pca10028 Long like this

 

  So develop nRF51822 When choosing pca10028 That's right .

 3、SDK explain

Reference blog   CSDN - Nordic nRF5 SDK

4、 Routine tests

4.1、  Bluetooth serial port test   ble_app_uart

  Compile the generated app Program ./_build/ble_app_uart_pca10028_s130.hex

Protocol stack program  s130_nrf51_2.0.1_softdevice.hex

4.2、 nRF Toolbox

 a、 choice UART

b、  Click on the device name to start the connection

c、 You can customize the Edit button and the sent data

 4、 Serial port sends data

 

  Test ok .
