My webapp consists of an main loop witch timers and a serial connection on a raspberry.
Every 10 seconds there is communication with an ewternal device via serial connection.
Everything works when my weppage loads when there is no communication.
But when I press F5 the same time I communicatie with the external device via serial comm. the message loop crashes and no timer events fires anymore.

Anybody that can decypher the errormessage above?
This would be very helpfull !

When you press F5, you are disconnecting/reconnecting to the server and by doing so destroy all B4J code in the class and create a new instance of the class. You should refresh the data in the WebApp yourself when your serial communication has new data:

This is pseudo code as I do not know how your app works:

B4X: 
sub serial_ReceivedNewData(data as string)
     Dim myLabel as ABMLabel = page.component("myLabel")
     myLabel.Text = data
     myLabel.Refresh  ' the new data will be shown in the webapp
end sub

Here's my code that decodes the string received from serial as you see at the bottom i do the refresh method :

        Case TYPESOORT_SOORTCONTROLLER_INTERACTION
            CRCresult = CheckNewCRC(s_recdata)
           
    End Select
   
   
    If CRCresult = True Then
        Dim newstr() As String = Regex.Split(Chr(3),s_recdata)
        If newstr.Length > 2 Then
            Dim data As String = newstr(1)

End Sub

I solved the problem.
The variable thats checks in my main thread if the page is open (pageopen).
I set it to true when the ws_connected event fired of my page, but this is wrong, I have to set it when ConnectPage event fires (at the end) so every component in my DOM is loaded.

Thanks to Alwaysbusy for pointing me to the right direction. (we got to meet up for a good belgian beer in Ypres ;))
