How to add GPIO control to ble_app_uart example

[dawidn47]

Hi, I have problem with using example codes. I want to add GPIO control to ble_app_uart example. Adding gpio_config() function taken from app_timer_tutorial blocks program (led which indicates advertising doesnt blink). Program is building correctly. It will be maybe connected with that when I want to run app_timer_tutorial I must to "erase all" with nRFgo otherwise I getting error in keil : Error: Flash Download failed - "Cortex-M4"

Thank you in advance.

Hi

To add GPIO action to e.g. ble_app_uart example in SDK 12.0.0, look at the bsp tutorial. You can simply insert the following code in the bsp_event_handler

	case BSP_EVENT_KEY_1: //On Button 2 press
			LEDS_INVERT(BSP_LED_1_MASK); //Changes the current state of LED_2
			break;	

then LED 2 on the nRF52-DK will toggle when you press BUTTON 2. Instead of blinking the LED, you can do whatever you want.
