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 (

Hi there, Let's say I initialize an AsyncStream like this: astreams1.Initialize(UsbSerial1.GetInputStream, UsbSerial1.GetOutputStream, "astreams1") It's possible after doing this to reinitialize it for "Write only" like this: astreams1 = Null astreams1.Initialize(Null, UsbSerial1.GetOutputStrea

It sends or receives the data and then closes the connection. Note that a new method was added to AsyncStreams that allows closing the channel after the data was sent (SendAllAndClose). Clients expect the data socket to be closed after the data is sent. There isn't any other cue that tells the clien

Well, your absolute first problem is going to be that you're using .InitializePrefix https://www.b4x..html#asyncstreams_initializeprefix InitializePrefix (In As Object, BigEndian As Boolean, Out As Object, EventName As String) Initializes AsyncStreams in prefix mode. This mode can only be used if

Many output streams buffer writes to improve performance. Rather than sending each byte to its destination as it’s written, the bytes are accumulated in a memory buffer ranging in size from several bytes to several thousand bytes. When the buffer fills up, all the data is sent at once. The flush() m
