Thank you Sigurd! I spent over an hour trying to figure out why only 4 of my buttons worked 🙂

A button press is a low power event, so you will need to increase GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS

is it something related to "NUMBER_OF_GPIO_TE = 4"??

I did exactly what you said. here is my code related the the buttons in my custom bsp header file.

#define BUTTONS_NUMBER 5
#define BUTTON_START   1
#define BUTTON_1       1
#define BUTTON_2       2
#define BUTTON_3       3
#define BUTTON_4       4
#define BUTTON_5       5
#define BUTTON_STOP    5
#define BUTTON_PULL    NRF_GPIO_PIN_PULLUP

#define BUTTONS_LIST { BUTTON_1, BUTTON_2, BUTTON_3, BUTTON_4, BUTTON_5}

#define BSP_BUTTON_0   BUTTON_1
#define BSP_BUTTON_1   BUTTON_2
#define BSP_BUTTON_2   BUTTON_3
#define BSP_BUTTON_3   BUTTON_4
#define BSP_BUTTON_4   BUTTON_5

#define BSP_BUTTON_0_MASK (1<<BSP_BUTTON_0)
#define BSP_BUTTON_1_MASK (1<<BSP_BUTTON_1)
#define BSP_BUTTON_2_MASK (1<<BSP_BUTTON_2)
#define BSP_BUTTON_3_MASK (1<<BSP_BUTTON_3)
#define BSP_BUTTON_4_MASK (1<<BSP_BUTTON_4)

//#define BUTTONS_MASK   0x000007FE
#define BUTTONS_MASK   0x0000003E

What is wrong with the code? FYI, I am using S130, 2.0.1, and ble_app_uart_c_s130 example.

I got

NRF_ERROR_INVALID_STATE (If button or GPIOTE has not been initialized). error from bsp_init.

With a custom board you will need to modify the board files.

You can find the board files under:

\SDK_INSTALL_FOLDER\examples\bsp

When creating a new board file, simply copy the pca10028.h file, rename it, and modify it after your requirements. Then you have to modify boards.h to support your new file, and add a new define that you can specify in the Keil options to include your modified file.
