    Default Creating Classes for DJI Tello

    This is kind of a beginner looking for the advice of more advanced programmers.

    When you send commands to the DJI Tello (Which is a small drone for those who don't know), it sometimes sends a response, such as "ok" to let you know that it received the command and its ready for instruction. I tried to set up a class that just listened to the Tello port, and in spectacular newbie fashion, of course I wasn't able to send any commands, because it was busy listening on that port.

    Is this something I likely coded wrong, or would it be best to just drop that class in so it runs whenever a command is sent instead of always waiting for a datagram package?

    What is the connection between the running java program and communications with the device?
    What is the Tello port? Serial, USB or ??
    If you don't understand my answer, don't ignore it, ask a question.

    The connection to the Tello is a wifi connection using UDP. The IP is 192.168.10.1 (i think), and the port is 8889.

    EDIT: My ultimate goal is to make a little GUI with buttons to control the drone while connected to my laptop. But I also want a good way to receive any messages from the device.

    So the connection/communication is via DatagramPackets?
    What is the protocol? Is the device like a server that waits for and responds to a client's request'?
    Does the device send unsolicited messages?
    If you don't understand my answer, don't ignore it, ask a question.
