Serial library and Android 4

[dsirio75]

Hi all, i have a problem with the serial library on an android 4 device (Galaxy Tab).

My app connects perfectly an OBD device with my motorola atrix (2.3.4) but when i try my app on Galaxy Tab (ICS) it won't connect.

Return me java exceptions saying "Invalid Exchange" and asks me to pair device again (i already did it).

Some idea? Tried Connect3 and ConnectInsecure with port 1 but didn't work...

Here's my code for the connection

Sub Admin_DiscoveryFinished
   ProgressDialogHide
   If foundDevices.Size = 0 Then
      ...
   Else
      Dim l As List
      l.Initialize
      For i = 0 To foundDevices.Size - 1
         Dim nm As NameAndMac
         nm = foundDevices.Get(i)
         l.Add(nm.Name)
      Next
      Dim res As Int
      res = InputList(l, "Select", -1)
      If res <> DialogResponse.CANCEL Then
         connectedDevice = foundDevices.Get(res)
         serial1.Connect(connectedDevice.Mac)
      End If
   End If
End Sub

Thanks

Seems like a bug in this specific Android version: Issue 32545 - android - Android dialog asks for pin code to pair during connect to socket, but device was already paired - Android - An Open Handset Alliance Project - Google Project Hosting

Can you update your OS?

I resolved with ConnectInsecure method, giving a random port. It works.
What problems may occur with an insecure connection?

The Bluetooth connection is not a secured connection. In most cases this is not a real issue.
