Using Erel's example of BT running it on the Chuwi, returns multiple same device. Around 80-100 it stops with the list found devices (all the same, all same MAC). Never seen this on any other device. Is this something new in android 8+?
code used for test/example
https://www.b4x.com/android/forum/threads/android-bluetooth-bluetoothadmin-tutorial.14768

bluetooth device is a HC05, but that doesnt matter with this example. This problem comes up also with the app which was build for the gps

here the code with maps to solve this issue

B4X: 
Private Sub Admin_DeviceFound (Name As String, MacAddress As String)
    Log(Name & ":" & MacAddress)
    If foundDevices.ContainsKey(MacAddress) Then
    Else
        foundDevices.Put(MacAddress, Name)
        ProgressDialogShow(ResourceStrings.Get("SEARCHDEVICE") & " (~ device found)...".Replace("~", foundDevices.Size))
    End If
End Sub
Sub Admin_DiscoveryFinished
    ProgressDialogHide

    Private i As Int
    If foundDevices.Size = 0 Then
        ToastMessageShow(ResourceStrings.Get("NODEVICE"), True)
    Else
        Dim l As List
        l.Initialize
        For i=0 To foundDevices.Size-1
                    l.Add(foundDevices.GetValueAt(i))
        Next
        InputListAsync(l, ResourceStrings.Get("DEVICECONNECT"), -1, True)
        Wait For InputList_Result (Index As Int)
        If Index <> DialogResponse.CANCEL Then
            ProgressDialogShow(ResourceStrings.Get("TRYCONNECT") & foundDevices.GetValueAt(Index) & " (" & foundDevices.GetkeyAt(Index) & ")")
            Serial1.Connect(foundDevices.GetkeyAt(Index))
        End If
    End If
End Sub
