B4A-Bridge is made of two components. One component is running on the device and the other is embedded in the IDE. The device side is the server side. It waits for connections and when a connection is established it handles the "action" messages. The code itself is made of a simple activity: https

For new projects it is recommended to use B4XSerializator instead of this solution. http://www.b4x.com/basic4android/images/SS-2013-11-14_13.26.52.png AsyncStreamsObject allows you to send and receive objects instead of bytes. You can read more about it here: http://www.b4x.-send-and-receive-obj

A new client has connected to the server so this event is raised. We create an AsyncStreams object that works with this socket. Now we need to store this AsyncStreams object. In this case the astream itself is used as the key and the value is an additional object which we will later use to show the

Hi to all! I need to connect to a physical (with laser) barcode reader via bluetooth, and I receive the barcode read using the AsyncStreams object. I need a MsgboxAsync inside both the "AsyncStreamReader_NewText (strBuffer As String)" and "AsyncStreamReader_Error" events. Since these are events not

the event sub should be in the class.

It depends on your app. Each AsyncStreams object uses two threads. The JVM is capable of handling hundreds of threads.

Thanks again for your reply. To better understand the technical feasibility of the solution I would like to implement, with an implementation based on AsyncStreams & Bluetooth serial, would it be possible for smartphone A to receive the objects from other n smartphones, (B, C, and E, for example), t

It is better to name the variable AST as it is an AsyncStreamsText object, not AsyncStreams object. AsyncStreams.Write - Expects an array of bytes. AsyncStreamsText.Write - Expects a string.
link: The issue is that you are encoding the String to a Data object and then sending the Data object to the AsyncStream which expects a String. You should
