nRF51_Unit_Testing

• This repository help you getting unit test result with Unity framwork from nRF51-DK board.
• This repository is modified from ble_app_uart_s110_pca10028.
• This repository contains test code which is not related with project working code. Only prove nRF51-DK can print test code result.

Need

• nRF51-DK
• Serial terminal program, e.g., Teraterm
• GNU Tools ARM Embedded 4.9.3
• Make for Windows - Complete package, except sources
• CoreUtils for Windows - Complete package, except sources
• nRFgo studio
• **reference this link "Before we begin" section.

1. Download repository and unzip

2. Connect nRF51-DK

3. Run Teraterm and config UART

• baudrate : 38400
• data : 8 bit
• parity : none
• stopbit : 1 bit
• control-flow : hardware

4. Run CMD and Type Commands

$ cd nRF51_Unit_Testing
$ make all
$ make flash_softdevice
$ make flash nrf51422_xxac_s110

5. Check test code result from Teraterm

6. Result
