that uses jSerial library to connect to an Arduino board. To see it working start with this simple B4R program: Sub Process_Globals Public Serial1 As Serial Private astream As AsyncStreams End Sub Private Sub AppStart Serial1.Initialize(115200) Log("AppStart") astream.Initialize(Serial1.Stream, "Astream_NewData", "Astream_Error") End Sub Sub... this mode the IDE will send a message to the serial connector to close the serial port during...

30278 30279 The RandomAccessFile libraries (B4A, B4J and B4i libs) include two new methods: WriteB4XObject and ReadB4XObject. These methods are similar to WriteObject and ReadObject. The main difference is that WriteObject / ReadObject methods are based on Java serialization feature. This means that they are not compatible with iOS. The new B4XObject methods use a custom serialization method and is therefore supported by all platforms. They are also faster than WriteObject...

Hello friends, This is my first but not last post in forum :D When I checked B4J_chat.zip file in Erel's post, I see that there is an old .fxml designer file that can not be recognized by B4J 9.8. I succeed to convert 1.fxml to 1.bjl file and succeed to make communicate Hercules (a terminal program) and B4J chat program by using AsyncStreamsText module. These are not a victory for a professional but for me it is. I explained usage of com0com (virtual serial port emulator) and Hercules in...
