Display Message on Lego NXT
I send a string message from a bluetooth device to Lego NXT mailbox, but is there anyway to display it on the NXT Robot?
Thank you.
This is difficult since the Bluetooth API does not expose this functionality. With the standard NXT firmware, your only choice would be to receive the message over bluetooth, and from a program running on the NXT pick it up and send the text using the Display block.
If you are using MSRS, then you will need to update the MSRS006 program block, or wait for the new LEGO NXT service which are due any time -- they do not require a program running on the brick, so you would be free to write your own and talk to it from MSRS on the PC.
In the next few weeks, we plan to release a new LEGO NXT add-on package for MSRS 1.5. This is a complete redesign of the LEGO services. This new package is designed from the ground up to be easy to use in our Visual Programming Language, and contains a sample VPL diagram along with a sample LEGO NXT program which does exactly what you are asking. Stay tuned for this release.
