Hello,
I have a brewing controller that I manufacture that has an integrated wifi radio. I use a Socket to communicate via TCP to my controller. I pass the socket to a astreams.
I've had issues with random disconnects from the B4A app to the radio. For years I've attributed these random disconnects to the embedded wifi radio I was using.
I recently switched to a different wifi device, and still get random disconnects. I then began to suspect it was my B4A app that had the issue. To test this theory, I installed 2 different TCP telnet terminal apps on my Android tablets and connected to the controller that way. With either one of those apps, the controller has never disconnected! With my B4A app, I get random disconnects ranging from 2 to 124 disconnects in a 24 hour period. I'm convinces it is my App causing the disconnects, not the hardware. Please look at what I'm doing and I'd appreciate anyone pointing out any issues with the code or maybe another approach. Thank you in advance for any help!
below is my code that handles the various socket connection routines.

below is my code that handles the various socket connection routines.
B4X:
Dim BBClientSocket As Socket 'for wifi implementation to Controller
Dim BBAstreams As AsyncStreams 'used for USB or wifi
the following is in my Activity_Create:
If MapBBParams.Get("wifiEnabled") = "true" Then
'using wifi, initialize that connection
BBClientSocket.Initialize("BBClientSocket")
'V1.20 use mapped parameters for ip address and port
BBClientSocket.Connect(MapBBParams.Get("BBIPAddress"), MapBBParams.Get("BBPort"), 5000)
lblBBConnectionStatus.Text = "Connecting"
End If
Sub BBClientSocket_Connected (Successful As Boolean)
If Successful Then
Try
BBClientSocket.TimeOut=10000 'added to force astreams error if clientsocket disconnects
BBAstreams.Initialize(BBClientSocket.InputStream, BBClientSocket.OutputStream, "BBAstreams")
Catch
Log("Error in BBClientSocket_Connected Try/Catch => " & LastException)
LogEvent("Error in BBClientSocket_Connected Try/Catch => " & LastException)
End Try
lblBBControllerConnectionStatus.Color = Colors.Green
lblBBControllerConnectionStatus.TextColor = Colors.Black
lblBBControllerConnectionStatus.Text="wifi Connected"
Log("controller connected via wifi!")
LogEvent("controller connected via wifi!")
Else
lblBBConnectionStatus.Color = Colors.Red
lblBBConnectionStatus.TextColor = Colors.Black
lblBBConnectionStatus.Text="Error Connecting"
End If
End Sub
The following code is called periodically in a timer routine to validate that the connection is still valid, and this gets triggered randomly.
'now check to see if we are connected via wifi
If BBClientSocket.Connected = False Then 'we are not connected, retry connecting . closing socket first
Log("Error -Controller Deemed Disconnected in RequestControllerDataTimer")
LogEvent("Error -Controller Deemed Disconnected in RequestControllerDataTimer")
BBAstreams.Close
BBClientSocket.Close
BBClientSocket.Initialize("BrewBossClientSocket")
BBClientSocket.Connect(MapBBParams.Get("BBIPAddress"), MapBBParams.Get("BBPort"), 5000)
End If
Below are my astreams errod routines:
Sub BBAstreams_Error
Log("BBAstreams Error - Controller Disconnected: " & LastException)
LogEvent("BBAstreams Error - Controller Disconnected: " & LastException)
lblBBControllerConnectionStatus.Color = Colors.Red
lblBBConnectionStatus.TextColor = Colors.Black
lblBBConnectionStatus.Text="Disconnected" 'V1.20 changed prompt
BBAstreams.Close
If MapBBParams.Get("wifiEnabled") = "false" Then
usb.Close
Else
BBClientSocket.Close
End If
End Sub
Sub BBAstreams_Terminated
Log("Astreams Terminated")
LogEvent("Astreams Terminated")
lblBBConnectionStatus.Color = Colors.Red
lblBBConnectionStatus.TextColor = Colors.Black
lblBBConnectionStatus.Text="Disconnected"
BBAstreams.Close
End Sub
