so now I suggest you put all this information into a new question, format it properly and ask it. Since all the information is now in a comment, it's likely nobody is going to read it and, since it's in a comment, it's a mess to read.

As I mentioned, I added this service into exiting code:

static void services_init(void) { dis_init(); bas_init(); hids_init(); lbs_init(); }

last line is the led button service, which comes right from example experimental_led blinky: static void lbs_init(void) { uint32_t err_code; ble_lbs_init_t init;

init.led_write_handler = led_write_handler;

err_code = ble_lbs_init(&m_lbs, &init);
APP_ERROR_CHECK(err_code);

}

Of course I added all relevant code for building and compile with no error. What I was expecting to see 1 more service which is a custom service in addition to device manager service and battery service, in my iphone which I am running some BLE scnner apps, but all I saw was device manger service and batter service only, no custom service!!. Am I missing something here? Also in hid keyboard example, during advertisement, in example code there is only one UUID number and type, like this:

static ble_uuid_t m_adv_uuids[] = {{BLE_UUID_HUMAN_INTERFACE_DEVICE_SERVICE, BLE_UUID_TYPE_BLE}};

I don't see any UUID for DI Service, and battery service, although it shows up as services in my iphone BLE scan app, which I don't understand. Now do I need to add the UUID of my custom service into advertisement init? I have seen some example they are adding all services in there, like HRS example: static ble_uuid_t m_adv_uuids[] = /**< Universally unique service identifiers. */ { {BLE_UUID_HEART_RATE_SERVICE, BLE_UUID_TYPE_BLE}, {BLE_UUID_BATTERY_SERVICE, BLE_UUID_TYPE_BLE}, {BLE_UUID_DEVICE_INFORMATION_SERVICE, BLE_UUID_TYPE_BLE} }; I am thinking may be its optional! I also added scan response part of lbs service into advertising _init(), the hid keyboard code was like this: err_code = ble_advertising_init(&advdata, NULL, &options, on_adv_evt, ble_advertising_error_handler); as you can see the second parameter is NULL, so I changed it to this: rr_code = ble_advertising_init(&advdata, &scanrsp, &options, on_adv_evt, ble_advertising_error_handler); Again it just like the example LED_BLINKY custom service, which scan response is pass into this code:

err_code = ble_advdata_set(&advdata, &scanrsp);

Please let me know if you need more information? Thanks

Yes it's perfectly possibly to add multiple services. Since you have given no details at all about what "didn't work" it's rather hard to suggest what your problem is.
