Do you have SBrick too?

No, I don't. Maybe Ashi can spare one for some time?

I added in Lego Blockly toolbox, in NXT new category named Messages, the Message WRITE and READ blocks.

You can write/read messages of type TEXT or a NUMBER (Floating point) to mailbox of a running program in the NXT.

Mailbox are numbered 1 to 10 in the dropdown to fit with NXT-G mailbox numbering but behind the scene, blockly uses 0-9...

I tested both Read and Write for both Text and Number.
Sometime the NXT does not detect to the MSG blockly sends, sometime it detects just fine... I don't know why.

To read or write a number you must check the Number? checkbox otherwise the default is text.

To write a number you can write you number in the default text field or use a Math Number block from the Math toolbox category.

 

Here are some examples:

NICE!

Mailbox messages are LEGO Blockly to NXT, and NXT to LBlockly, correct? As I can compose outgoing NXT messages also in BricxCC, I can read the reply in LBockly, right?

Yes.

I used NXT-G to make very basic NXT programs that I uploaded into the NXT brick to test the messaging.

And from what I read, BricxCC uses the same FW as the official Lego NXT FW so the Direct Command protocol remains the same.

Even the Enhanced NBC/NXC Firmware kept the original Direct Command protocol intact if I understand well.

Can confirm: Yes, that worked/works as well!

Cool.
