Now I use following sleep_mode_enter() will be reset immediately ,can not enter sleep mode to wait button1 for wake up.

static void sleep_mode_enter(void)
{

 ret_code_t err_code;
nrf_drv_twi_uninit(&m_twi); //keli

nrf_gpio_cfg_sense_input(BUTTON1_GPIO_PIN,NRF_GPIO_PIN_PULLUP,NRF_GPIO_PIN_SENSE_LOW);
//nrf_gpio_cfg_sense_input(BUTTON2_GPIO_PIN,NRF_GPIO_PIN_PULLUP,NRF_GPIO_PIN_SENSE_LOW);
//nrf_gpio_cfg_sense_input(BUTTON3_GPIO_PIN,NRF_GPIO_PIN_PULLUP,NRF_GPIO_PIN_SENSE_LOW);
//nrf_gpio_cfg_sense_input(BUTTON4_GPIO_PIN,NRF_GPIO_PIN_PULLUP,NRF_GPIO_PIN_SENSE_LOW);

NVIC_DisableIRQ(GPIOTE_IRQn);
NVIC_ClearPendingIRQ(GPIOTE_IRQn);

err_code = bsp_indication_set(BSP_INDICATE_IDLE);
APP_ERROR_CHECK(err_code);

// Prepare wakeup buttons.
err_code = bsp_btn_ble_sleep_mode_prepare();
APP_ERROR_CHECK(err_code);

// Go to system-off mode (this function will not return; wakeup will cause a reset).
err_code = sd_power_system_off();
APP_ERROR_CHECK(err_code);

}
