I see my phone does say that notifications and indications is disabled. But where do i enable it?

Sorry, but i am a little confused over the notification thing. Where should i enable notifications? Is it in my bas_init?

    static void bas_init(void)

{ uint32_t err_code; ble_bas_init_t bas_init_obj;

memset(&bas_init_obj, 0, sizeof(bas_init_obj));

bas_init_obj.evt_handler          = on_bas_evt;
bas_init_obj.support_notification = true;
bas_init_obj.p_report_ref         = NULL;
bas_init_obj.initial_batt_level   = 100;

BLE_GAP_CONN_SEC_MODE_SET_OPEN(&bas_init_obj.battery_level_char_attr_md.cccd_write_perm);
BLE_GAP_CONN_SEC_MODE_SET_OPEN(&bas_init_obj.battery_level_char_attr_md.read_perm);
BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS(&bas_init_obj.battery_level_char_attr_md.write_perm);

BLE_GAP_CONN_SEC_MODE_SET_OPEN(&bas_init_obj.battery_level_report_read_perm);

err_code = ble_bas_init(&m_bas, &bas_init_obj);
APP_ERROR_CHECK(err_code);

}

Thanks! I will look into that tomorrow :-)

Make sure that notification is enabled, the saadc_event_handler isn't called before notification is enabled from your phone:

Well that should be your first thing to check - are you getting reasonable readings from the ADC?

Nothing. It doesn't output anything in RTT viewer..

SEGGER_RTT_printf(0, "adc_result: %d\n", adc_result);

So what does this tell you?

Hi,

Take a look at this answer.
