Cannot connect to device using Service UUIDs

Prerequisites

• I am running the latest version
• I checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed

Expected Behavior

BleManager.startDeviceScan should emit callback when serviceUUIDs are present on peripheral.

Current Behavior

BleManager.startDeviceScan does not emit callback when serviceUUIDs are present.

Steps to Reproduce

1. Use array of one or more strings to filter peripherals scanned by service UUID.
2. Callback is not fired
3. Set service UUIDs to null
4. Callback is fired for all peripherals

Context

Current environment:

{
  "react": "16.8.3",
  "react-native": "0.59.3",
  "react-native-ble-plx": "1.0.3"
}

The code below demonstrates the problem:

const bleManager = new BleManager();
bleManager.onStateChange(state => {
    if (state !== "PoweredOn") return
    bleManager.startDeviceScan(
        ["053d03fd-00b0-4331-a337-f49f59777484"], // change this value to null to and all peripherals are called
        null,
        (error, scannedDevice) => {
            if (error) console.error(error);
            bleManager.connectToDevice(scannedDevice.id).then(connectedDevice => {
                return connectedDevice.discoverAllServicesAndCharacteristics()
            }).then(connectedDevice2 => {
                return connectedDevice2.services()
            }).then(services => {
                console.log(services.map(x=>x.uuid));
            })
        }
    )
})

After changing services to null, the service UUIDs are printed in console. I have tried to copy/paste the array for the services and running again, but the peripheral is still not found.

Is 053d03fd-00b0-4331-a337-f49f59777484 present in advertisement data? You can check scannedDevice.serviceUUIDs field to check if this UUID is visible. If not, then that’s expected behavior.

I am unfortunately having a same problem. Some fields are actually missing in connectToDevice promise

this.manager.startDeviceScan( null, null, (error, device) =>{
    if( error ){ console.log( error ); }

    if( device.id = "24:0A:C4:32:31:32" ){
            console.log( device ); //  serviceUUIDs, localName, rssi, txPowerLevel, are present
            this.manager.stopDeviceScan();
            
            this.manager.connectToDevice( device.id, { autoconnect: true } ).then( deviceConnected => {
                 return deviceConnected.discoverAllServicesAndCharacteristics();
            }).then( deviceConnected2 => {
                console.log( deviceConnected2 ); // none of fields above are present now
            });
        }
        
    });`
