Hi Joao,

Your buttons_init() does not initialize the bsp correctly and it did not initialize the BSP BLE Button Module. Please refer to buttons_leds_init() in the Template Application example to see how to initial BSP (bsp_init) and initializing the BSP BLE Button Module (bsp_btn_ble_init).

/**@brief Function for initializing buttons and leds.
 *
 * @param[out] p_erase_bonds  Will be true if the clear bonding button was pressed to wake the application up.
 */
static void buttons_leds_init(bool * p_erase_bonds)
{
    ret_code_t err_code;
    bsp_event_t startup_event;


    err_code = bsp_init(BSP_INIT_LEDS | BSP_INIT_BUTTONS, bsp_event_handler);
    APP_ERROR_CHECK(err_code);

    err_code = bsp_btn_ble_init(NULL, &startup_event);
    APP_ERROR_CHECK(err_code);

    *p_erase_bonds = (startup_event == BSP_EVENT_CLEAR_BONDING_DATA);
}

If you enable NRF_LOG_BACKEND_UART_ENABLED in the config.h as

// <e> NRF_LOG_BACKEND_UART_ENABLED - nrf_log_backend_uart - Log UART backend
//==========================================================
#ifndef NRF_LOG_BACKEND_UART_ENABLED
#define NRF_LOG_BACKEND_UART_ENABLED 1
#endif

You could see the log in the terminal tool like putty. The log will indicate where is wrong.

Hi Amanda

I'm using the nRF5_SDK_15.3.0 version.

I will study that, but for now can you tell me if my code is incorrect or what could be happening to the leds not be working?

With my best

Hi Joao,

Which version of SDK are you using?

You should study the Template Application example to see how to initial BSP (bsp_init) and initializing the BSP BLE Button Module (bsp_btn_ble_init).
