It is part of RandomAccessFile library. Make sure NOT to use prefix mode with your VB.Net app. Tip: start with this example: Network + AsyncStreams + B4XSerializator

New video tutorial: 256762156 AsyncStreams allows you to read data from an InputStream and write data to an OutputStream without blocking your program. The reading and writing are done with two separate threads. When new data is available the NewData event is raised with the data. When you write

No. All the communication happens in the background. You can call AStream.SendAllAndClose to make it close automatically after it is done sending.

Please use code here... tags when posting code. AsyncStreams (in non-prefix mode) returns the data exactly as it returned from the native code. I'm not sure that I understand your code. Use the debugger and check the values of buffer before you do anything else with the data.

You should try using the forum search facility. AsyncStreams is part of the RandomAccessFile library

J'ai peu d'expérience dans ce domaine, mais je me suis amusé avec Arduino pour écrire la documentation pour B4R. Dans B4A, pour AsynchStreams il y a deux méthodes d'initialisation: AsynchStreams.Initialize (In As InputStream, Out As OutputStream, EventName As String) AsynchStreams.InitializePrefix (

If you are only writing then there is no difference. AsyncStreams takes care of checking whether there is new data and raises the NewData event when the data is available. AsyncStreams also raises the Disconnected event if the connection breaks. However it will never happen with serial ports.
link: My mistake. I'm too used to working with AsyncStreams. If you are only writing to the stream then use: Serial1.Stream.WriteBytes(ArrayAs Byte(0x99, 0
link: It's worked! Yes, I asking for this example because I found many of the example in this forum using "AsyncStreams" and I'm not quite understand wha

It doesn't matter. Your code always runs on the main thread. Make sure that nothing in your code runs slow and everything will work. AsyncStreams takes care of managing the network communication using background threads.

AsyncStreams is used from socketserver in order to have managed client LAN connections into the same app that is running the websocket server, in order to push messages from my old VB6 app to the websocket server and vice versa (as real-time as allowed)! May this is the problem. Is there any other w
link: Server solutions are always multithreaded. Each websocket connection is handles with its own thread. I don't know what you did with AsyncStreams but

The AsyncStreams reading and writing are done with two separate threads. it works in the background. I think the problem is how you handle the incoming data rather than manage it to background.
link: Yes but when debugging. For example when my programm is in a loop doine something, and then data is coming then it goes to asyncstreamsnewdata and com
