error: invalid length in advertising init

Question

hii... 
 i hv maufature_array of size 7 to advertise.... am facing a problem while advertising battery level service with dat... my code is lyk dis 
 uint32_t err_code;
 uint8_t flags =BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
 ble_advdata_t advdata1;
 ble_advdata_service_data_t service_data[1];
ble_advdata_manuf_data_t manuf_specific_data;
uint8_t manuf_data_array[6];	

manuf_data_array[0] = 0x01;
manuf_data_array[1] = 0x02;
manuf_data_array[2] = 0x03;
manuf_data_array[3] =0x04;
manuf_data_array[4] = 0x05;
manuf_data_array[5] = 0x06;

manuf_specific_data.company_identifier = COMPANY_IDENTIFER; /* COMPANY IDENTIFIER */
manuf_specific_data.data.p_data = manuf_data_array;
manuf_specific_data.data.size = sizeof(manuf_data_array);

uint8_t battery = do_battery_measurement();
service_data[0].service_uuid = BLE_UUID_BATTERY_SERVICE;
service_data[0].data.p_data = &battery;
service_data[0].data.size = sizeof(battery);


// Build and set advertising data
memset(&advdata1, 0, sizeof(advdata1));

advdata1.name_type = BLE_ADVDATA_FULL_NAME;
advdata1.flags.size = sizeof(flags);
advdata1.flags.p_data = &flags;
advdata1.p_service_data_array = service_data;
advdata1.service_data_count = 1;
advdata1.p_manuf_specific_data = &manuf_specific_data;

err_code = ble_advdata_set(&advdata1, NULL);
APP_ERROR_CHECK(err_code);

A BLE advertising packet contains at most 31 bytes data. You can try putting some data into the scan response, another 31bytes packet. For instance, 
 uint32_t err_code;
ble_advdata_t advdata;
ble_advdata_t scanrsp;

uint8_t flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

ble_uuid_t adv_uuids[] =
{
 {BLE_UUID_BATTERY_SERVICE, BLE_UUID_TYPE_BLE},
 {BLE_UUID_HEART_RATE_SERVICE, BLE_UUID_TYPE_BLE},
 {BLE_UUID_DEVICE_INFORMATION_SERVICE, BLE_UUID_TYPE_BLE},
 {BLE_UUID_NUS_SERVICE, m_nus.uuid_type}
}; // Too long to fit all in advdata

// Build and set advertising data
memset(&advdata, 0, sizeof(advdata));
memset(&scanrsp, 0, sizeof(scanrsp));

advdata.name_type = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = true;
advdata.flags.size = sizeof(flags);
advdata.flags.p_data = &flags;
scanrsp.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]);
scanrsp.uuids_complete.p_uuids = adv_uuids;

err_code = ble_advdata_set(&advdata, &scanrsp);
APP_ERROR_CHECK(err_code);
