All devices scanned have name equals to null

Expected Behavior

Scanning devices should return a name in order to understand which device is which.

Current Behavior

Scanning devices return objects with name and localName equals null:

Device {
    id : "2C:F0:EE:19:27:CF"
    isConnectable : null 
    localName : null
    manufacturerData : "TAAQBQsUluNJ"
    mtu : 23
    name : null
    overflowServiceUUIDs : null
    rssi : -62 
    serviceData : null 
    serviceUUIDs : null 
    solicitedServiceUUIDs : null 
    txPowerLevel : null
    _manager : BleManager
    __proto__ : Object
}

I don’t understand how this library reports device name and localName as null. I simply logged all detected devices, and every single one, null. Using my smartphone to see all bluetooth devices in the area reveals them with human readable names. Therefore, they are reporting them. I instantiated a manager and scanned for devices. Is there a step i missed?

@tyrone2kx oddly enough, it started displaying showing the names soon after. I also noticed sometimes the scan results had duplicates. One might show the name, while the other might not.

It might help to log all the scan results and closely inspect.
