Android Question felUsbSerial and debug mode

[adrian_eb]

Hi there,

Im working on a Android TV box and arduino connected by USB (USB device number 9025), Im using the felUsbSerial 1.12, I made the program find the correct device, open it and it works perfect, but only in Debug mode, if I switch to Release, I get a java error (using BridgeLogger: true )
I feel the code is OK, and something is working on another way by switching Debug/Release, it is some permission missing? any clue?

Thanks in advance

Dim UsbDevices() As UsbDevice
    UsbDevices = manager.GetDevices
    If UsbDevices.Length = 0 Then
        ToastMessageShow("ERROR no hay dispositivos USB conectados", True)
    Else
        For z = 0 To UsbDevices.Length - 1
            Dim UsbDvc As UsbDevice
            UsbDvc = UsbDevices(z)
            Log("USBDeviceNr. " & z & " - UsbPid = " & UsbDvc.ProductId & " Devicename:" & UsbDvc.DeviceName)
            Log("USBDeviceNr. " & z & " - Vendor id = " & UsbDvc.VendorId & " Device ID: " & UsbDvc.DeviceId )
            Log("listado de dispositivos")
            Log("Vendor ID")
            Log(UsbDvc.VendorId)
            If UsbDvc.VendorId == 9025 Then   
                dispositivo = z
                Log( "Este = " & dispositivo)
            End If
        Next
    End If

    If manager.GetDevices.Length = 0 Then
        Log("No connected usb devices.")
        ToastMessageShow("ERROR no hay dispositivos USB conectados", True)
    Else
        Dim device As UsbDevice = manager.GetDevices(dispositivo)
        If manager.HasPermission(device) = False Then
            ToastMessageShow("Please allow connection and click again.", True)
            manager.RequestPermission(device)
        Else
            Log("Conectando " )
            enchufado = True
            usbserial.Initialize("serial", device, -1)
            usbserial.BaudRate = 9600
            usbserial.DataBits = usbserial.DATA_BITS_8
            usbserial.StartReading
            Log("Conectado! ")
            ToastMessageShow("Connection OK", True)           
        End If
    End If

java.lang.Exception: Sub serial_dataavailable was not found.

The error seems clear.

Do you HAVE an eventsub with the name serial_dataavailable?

I see that too, but, It works perfect on Debug mode, it looks that the lib can't access the USB device, the lib has to create that sub, right?

No, a lib can not create a sub in your code.

If you use the serial object then it is up to you to implement the needed Eventsubs.

I suggest to go over the example code from the felusbseriel library again.
And, hopefully, copy the code you did not copy the first time.

Thanks!!! yes, I just copy/paste "all" the code Im using, but forgot to cut/paste the Sub on the example to my code!

Private Sub serial_DataAvailable (Buffer() As Byte)

That part was missing! Thanks!

Its working now, but... why on debug mode worked and on release dont? weird
