Changing BLE UUID causes Boron to not be discoverable on IOS

Connectivity BLE // NFC
1

Hello, I am using the 1.4.4 version OS for developing a BLE program. I have attached my code below.

// This #include statement was automatically added by the Particle IDE.
#include <CellularHelper.h>

// This #include statement was automatically added by the Particle IDE.
#include <DiagnosticsHelperRK.h>


//SYSTEM_MODE(MANUAL);

#define DEBUG_BUILD

BleAdvertisingData advData;
BleUuid hogpService(0x1812);
BleUuid deviceInfoService(0x180A);


#define BLE_WIRING_DEBUG_ENABLED 1

SerialLogHandler serialLogHandler(LOG_LEVEL_TRACE);


BleCharacteristic batLevelStateCharacteristic("batState", BleCharacteristicProperty::READ, BleUuid(0x2A1B), deviceInfoService);
BleCharacteristic powerSourceCharacteristic("powerSource", BleCharacteristicProperty::READ, BleUuid(0x2A1A), deviceInfoService);
BleCharacteristic batPowerCharacteristic("batLevel", BleCharacteristicProperty::READ, BleUuid(0x2A19), deviceInfoService);
BleCharacteristic signalStrengthValueCharacteristic("signalStrength", BleCharacteristicProperty::NOTIFY, BleUuid("247e76c8-9dd4-412d-a75b-5244ad4cb8f4"), deviceInfoService);


system_tick_t begin;

void setup() {

	advData.appendServiceUUID(hogpService);
	
  	BLE.addCharacteristic(batLevelStateCharacteristic);
  	BLE.addCharacteristic(powerSourceCharacteristic);
    BLE.addCharacteristic(batPowerCharacteristic);
    BLE.addCharacteristic(signalStrengthValueCharacteristic);
	

	advData.appendLocalName("Boron");
	
	BLE.advertise(&advData);
	begin = millis();

}

void loop() {


	if(BLE.connected()) {

		if ((millis()-begin) > (6*1000)) {
			// reportChar.setValue(value, 8);
			//protocolChar.setValue((uint8_t)1);
			begin = millis();
			// reportChar.setValue(value, 8);
			
		    // BATTERY_STATE_UNKNOWN = 0,
			// BATTERY_STATE_NOT_CHARGING = 1,
			// BATTERY_STATE_CHARGING = 2,
			// BATTERY_STATE_CHARGED = 3,
			// BATTERY_STATE_DISCHARGING = 4,
			// BATTERY_STATE_FAULT = 5,
			// BATTERY_STATE_DISCONNECTED = 6
			uint8_t batState = (uint8_t) DiagnosticsHelper::getValue(DIAG_ID_SYSTEM_BATTERY_STATE);
			batLevelStateCharacteristic.setValue(batState);
		    
		    // POWER_SOURCE_UNKNOWN = 0,
			// POWER_SOURCE_VIN = 1,
			// POWER_SOURCE_USB_HOST = 2,
			// POWER_SOURCE_USB_ADAPTER = 3,
			// POWER_SOURCE_USB_OTG = 4,
			// POWER_SOURCE_BATTERY = 5
		    uint8_t powerSource = (uint8_t) DiagnosticsHelper::getValue(DIAG_ID_SYSTEM_POWER_SOURCE);
			powerSourceCharacteristic.setValue(powerSource);

			// Diagnostics data is a fixed point number, convert to integer 0-100 %
			//Use little or big endian
			uint8_t batLevel = (uint8_t) (DiagnosticsHelper::getValue(DIAG_ID_SYSTEM_BATTERY_CHARGE) >> 8);
			batPowerCharacteristic.setValue(batLevel);
			
			//Signal strength
			//uint8_t signalStrength = (uint8_t) (DiagnosticsHelper::getValue(DIAG_ID_NETWORK_SIGNAL_STRENGTH_VALUE));
			//signalStrengthValueCharacteristic.setValue(signalStrength);
			CellularHelperRSSIQualResponse rssiQual = CellularHelper.getRSSIQual();
            uint8_t bars = (uint8_t)CellularHelperClass::rssiToBars(rssiQual.rssi);

            //Log.info("rssi=%d, qual=%d, bars=%d", rssiQual.rssi, rssiQual.qual, bars);
            signalStrengthValueCharacteristic.setValue(bars);
		}

	}

I would like to change advData.appendServiceUUID to advertise deviceInfoService. However everytime i changed the service and flashed it to boron, my IOS device cannot sense the particle boron. I have tried this on an Android device and it is able to pick up the signal so it should be an IOS specific problem.
