Help on connection to OPPO phone

[rubenmonteiro]

Hi.
I'm using your nuget to connect to a Bluetooth device, I'm using my phone as a sandbox to test my code.
My basic code is this

    internal class Program
    {
        static bool IsServicesResolved;
        static async Task Main(string[] args)
        {
            Console.WriteLine("Searching Bluetooth devices");
            var adapter = await BlueZManager.GetAdapterAsync("hci0");
            adapter.DeviceFound += adapter_DeviceFoundAsync;
            Console.WriteLine("Searching devices");
            await adapter.StartDiscoveryAsync();
            await Task.Delay(TimeSpan.FromSeconds(10));
            await adapter.StopDiscoveryAsync();
            var devices = await adapter.GetDevicesAsync();
            Console.WriteLine("Choose Device");
            for (int i = 0; i < devices.Count; i++)
            {
                Console.WriteLine($"{(i + 1)} => {(await devices[i].GetNameAsync())}");
            }
            var index = Console.ReadLine();
            var device = devices[int.Parse(index) - 1];
            device.ServicesResolved += device_ServicesResolved;
            await device.ConnectAsync();
            await Task.Delay(TimeSpan.FromSeconds(5));
            var connected = await device.GetConnectedAsync();
            Console.WriteLine($"Device connected: {connected}");
            var paired = await device.GetPairedAsync();
            if (!paired)
            {
                await device.PairAsync();
                await Task.Delay(TimeSpan.FromSeconds(5));
                paired = await device.GetPairedAsync();
            }
            Console.WriteLine($"Device is paired: {paired}");

            while (!IsServicesResolved)
            {
                Console.Clear();
                Console.WriteLine($"{DateTime.Now}");
                await Task.Delay(TimeSpan.FromSeconds(500));
            }
            Console.WriteLine("Services resolved");
            var services = await device.GetServicesAsync();
            var deviceProp = await device.GetPropertiesAsync();
            var deviceUUID = await device.GetUUIDsAsync();
            foreach (var uuid in deviceUUID)
            {
                var service = await device.GetServiceAsync(uuid);
                if (service == null)
                    Console.WriteLine($"No service for UUID: {uuid}");
                else
                    Console.WriteLine($"Service for UUID: {uuid}");
            }
            Console.ReadLine();
        }

        private static Task device_ServicesResolved(Device sender, BlueZEventArgs eventArgs)
        {
            IsServicesResolved = true;
            return Task.CompletedTask;
        }

        private static async Task adapter_DeviceFoundAsync(Adapter sender, DeviceFoundEventArgs eventArgs)
        {
            Console.WriteLine($"Device Found: {(await eventArgs.Device.GetNameAsync())}");
        }

    }

The issue I'm facing is that I don't have any services that I can connect to, this is the console output:

1 => OPPO A73 5G
1

Can anybody give some idea on this, because the same list of UUIDS in the Bluetooth linux console returns the UUIDS names
