Then there will be some coding required. You can send direct commands remotely using a library such as leJOS or MonoBrick. You could use these to draw on the display. However, if there is a program running on the NXT that has Display blocks, it will write over whatever you sent each time it gets to a Display block in the program.

<p>I just had an idea. Have the output of the bluetooth message receiver block run into the input of the display block. Then, I have some other device sending messages that I type in.</p>

<p>I'm planning to use NXT to troll my friends, and I want to show something on the screen that I send to it via Bluetooth. To clarify, I want to type it on a computer in another room. Is there a way to do this all in the NXT software? (no coding)
Thanks - Sam.</p>

Are you using a NXT or EV3? I think I could help you with that problem :)
