Not quite in place; the “GenericBrick.cs” class has a constructor which doesn’t take a bool ‘isEv3’, but tries to automatically detect whether a brick is NXT or EV3. This also has not worked yet. I tried updating it to do a similar thing to the ‘resetConnection()’ method, but so far no luck:

public GenericBrick(string newBrickName, string newConnName)
{
    brickName = newBrickName + "";
    connName = newConnName + "";
    state = STATE_NEW;

    // first, try to connect as if it is an NXT
    connectToBrick(false, true);
    if (state == STATE_NXT)
        return;

    // not a found NXT?
    if (nxtBrick != null)
    {
        if (nxtBrick.Connection != null)
            nxtBrick.Connection.Close();
    }
    nxtBrick = null;

    // try to connect as if it is an EV3
    connectToBrick(true, true);
}

However, in the meantime I wrote the Winforms UI to pop a dialog box asking if a brick is EV3 or NXT. That will work for the near term.

Huh! I’d swear in the past I had written code which tried to call Brick.Connection.Close(), and that did not work – yet when I just updated my class here, now the process works. Good news, regardless!

The updated “GenericBrick.txt” class is attached. I refactored the brick connection code into its own method (rather than being in the constructor), so I could reuse it in the ‘reset’ method, e.g.:

public int resetBrokenState()
{
    if (state == STATE_BROKEN)
    {
        if (ev3Brick != null)
        {
            ev3Brick.Connection.Close();
            connectToBrick(true, false);
            //state = STATE_EV3;
        }
        else
        {
            nxtBrick.Connection.Close();
            connectToBrick(false, false);
            //state = STATE_NXT;
        }
    }

    return state;
}

Whoops, it wouldn’t let me attach *.cs files. Trying again with *.txt files – if these work, just rename them to *.cs and drop them into the “\TestApplication” folder in the MonoBrick Test Project.

Edit: And also, I apologize in advance for any bad coding practices you see. I’m brand-new to C# development. ^_^;;
