Adding service_data to advertising (custom service)

Question

Hi guys, 
 i asked a similar question [1] few days ago, but yesterday i stumbled over the "service_data" type when advertising packages. 
 I've written a custom service (uuid: 0x1004) with a custom base-uuid (i don't know if its necessary to mention :).
Is it now possible to send additional information corresponding to this custom service? Or is the usage of the service_data just allowed for registered services of Bluetooth SIG? 
 ble_advdata_service_data_t srv_data;
uint8_array_t data_array;
uint8_t data[1];

data[0] = 0x01
data_array.p_data = data;
data_array.size = sizeof(data);
srv_data.service_uuid = SERVICE_UUID;
srv_data.data = data_array;

[...]
advdata.p_service_data_array = &srv_data;
advdata.service_data_count = 1;
 
 apparently it will be send, but in service data nothing shows up:
 
 Thanks in advance,
cheers!

Use manufacturer specific data: 
 // Variables used for manufacturer specific data
ble_advdata_manuf_data_t adv_manuf_data;
uint8_array_t adv_manuf_data_array;
uint8_t adv_manuf_data_data[2];

// Configuration of manufacturer specific data
adv_manuf_data_data[0] = 0xAA;
adv_manuf_data_data[1] = 0xBB;

adv_manuf_data_array.p_data = adv_manuf_data_data;
adv_manuf_data_array.size = sizeof(adv_manuf_data_data);

adv_manuf_data.company_identifier = 0xFF00;
adv_manuf_data.data = adv_manuf_data_array;

advdata.p_manuf_specific_data = &adv_manuf_data;
 
 You can additionaly add manufacturer specific data field in scan response packet: 
 ble_advdata_t advdata;
ble_advdata_t scanrsp;

// Variables used for manufacturer specific data
ble_advdata_manuf_data_t adv_manuf_data;
uint8_array_t adv_manuf_data_array;
uint8_t adv_manuf_data_data[2];

ble_advdata_manuf_data_t scanrsp_manuf_data;
uint8_array_t scanrsp_manuf_data_array;
uint8_t scanrsp_manuf_data_data[27];

// Build and set advertising data
memset(&advdata, 0, sizeof(advdata));

...

// Configuration of manufacturer specific data
adv_manuf_data_data[0] = 0xAA;
adv_manuf_data_data[1] = 0xBB;

adv_manuf_data_array.p_data = adv_manuf_data_data;
adv_manuf_data_array.size = sizeof(adv_manuf_data_data);

adv_manuf_data.company_identifier = 0xFF00;
adv_manuf_data.data = adv_manuf_data_array;

advdata.p_manuf_specific_data = &adv_manuf_data;

// Build and set scan response data
memset(&scanrsp, 0, sizeof(scanrsp));

...

// Configuration of manufacturer specific data
scanrsp_manuf_data_data[0] = 0xCC;
scanrsp_manuf_data_data[1] = 0xDD;

scanrsp_manuf_data_array.p_data = scanrsp_manuf_data_data;
scanrsp_manuf_data_array.size = sizeof(scanrsp_manuf_data_data);

scanrsp_manuf_data.company_identifier = 0xFF00;
scanrsp_manuf_data.data = scanrsp_manuf_data_array;

scanrsp.p_manuf_specific_data = &scanrsp_manuf_data;

err_code = ble_advdata_set(&advdata, &scanrsp);
APP_ERROR_CHECK(err_code);
 
 This works for me: 
 ble_advdata_t scanrsp;
ble_advdata_service_data_t srv_data;
uint8_array_t data_array;
uint8_t data[6];
data_srv[0] = 0xAA;
data_srv[1] = 0xBB;
data_srv[2] = 0xCC;
data_srv[3] = 0xDD;
data_srv[4] = 0xEE;
data_srv[5] = 0xFF;
data_array.p_data = data;
data_array.size = sizeof(data);
srv_data.service_uuid = BLE_UUID_TX_POWER_SERVICE;
srv_data.data = data_array;

memset(&scanrsp, 0, sizeof(scanrsp));
scanrsp.p_service_data_array = &srv_data;
scanrsp.service_data_count = 1;

err_code = ble_advdata_set(&advdata, &scanrsp);
APP_ERROR_CHECK(err_code);
 
 It seems it didn't work for you because in your advdata packet was not enough free space for your service_data.
