Android Question Astreams.Write error

[Declan]

I am using AsyncStreamsText to communicate with an Arduino via the USB port.
My code to Write:

Sub spnrTransferStock_ItemClick (Position As Int, Value As Object)
    If Value <> "SELECT AREA TO TRANSFER STOCK TO" Then
        lblTransferStockTip.Text = "SCAN PRODUCT TO TRANSFER"
' Switch Scanner ON
    Dim stringTX As String
    stringTX = "s" & Chr(13) & Chr(10)
    astreams.Write(stringTX)
    End If
End Sub

Initialization occurs here:

Sub ConnectUSB
        If usb.UsbPresent = usb.USB_NONE Then
        Log("Msgbox - no device")
        Msgbox("No USB device or accessory detected!", "Error")
        Log("Msgbox - returned")
        Return
    End If
    Log("Checking permission")
    If (usb.HasPermission) Then
'        Msgbox(usb.DeviceInfo, "Device Information")
        Dim dev As Int
        dev = usb.Open(9600)       
        If dev <> usb.USB_NONE Then
            astreams.Initialize(Me, "astreams",usb.GetInputStream,usb.GetOutputStream)
        Else
            Log("Error opening USB port")
        End If
    Else
        usb.RequestPermission
    End If
End Sub

But I receive this error:

But astreams is initialized?

Why aren't you using rapid debug mode?

Dunno - never tried rapid debug
I finaly resolved the issue I was having - block commented the initialize out
