Creating handshake communication (dump request/reply)

[yosogawa]

I'm trying to do a handshake type (e.g. dump request) MIDI SysEX communication, but it's not working. Of course, sending and receiving are working fine.

What I want to do is "use an asynchronous awaiting mechanism with a timeout, and after receiving data, perform pattern matching on a part of the data to determine whether it is appropriate, and only return data that passes the test to the user."

Can you give me any hints, including whether it is possible to configure it just by using the current API? Maybe I need to create a replacement for onMidiDataReceived()?

MidiCommand.onMidiDataReceived() is a Stream model.
There is no causal relationship between Sending Message and Receiving Message.
If there is, it can be assumed that the message output to the same MIDI port with a timestamp after the target receives the request is a reply to this case.
