Respected sir, setup for programming = Eclipse-gcc-toolchain-setup board = PCA10040
as per my way first take a ble_app_uart code startup my coading purpose. then we include pin_change_int(like merge both code). do not any change in "config" file and "make" file.
just add one change in "gpio_int" function like "BSP_BUTTON_1" instead of "BSP_BUTTON_0" and "BSP_LED_1" instead of "BSP_LED_0". because "BSP_LED_0" and "BSP_BUTTON_1" both alredy use in "ble_app_uart".
