Erel, Check out the logcat. Do a search for java.io.IOException: [JSR82]. I get this Error once in while. Maybe for every 6-10 attempts. I use 3 attempts to make sure I close the Astream or else Unpair/Pair is required. If first attempt does not close the Astream then 2nd will and with 100% of the time will close it successfully.


B4X: 
Dim x As Int
   For x = 1 To 3
      If Astreams.IsInitialized Then
         Try
            Log("Attempt " & x)
            Log("Astream.Close")
            Astreams.Close
            Log("Serial1.Disconnect")
            Serial1.Disconnect
            Exit
         Catch
            Log(LastException.Message)
         End Try
      End If
   Next

I duplicated the exception fault with try catch removed. I had to compress the txt file. It is too large.

java.io.IOException: [JSR82] close: destroy() failed.

It seems like an issue with this specific device. Which model are you using?
