Hi everyone !
I am trying to send and receive data between two NXT, but do not know how. I post this new topic, hope anyone can help me, solve problems send and receive data between two NXT or anyone send for me few of your documents or code.
Thanks so much !

Ok so you may do this via Bluetooth but that is the only way i could possibly think of doing it unless you could get a cord like an a to a cord but with the trapezoid USB cord. Sorry i wish i could help more and why are you trying to do this?

BT and RS485 are the only two methods that don't rely on some other form of processor or other IC(s).

What do you mean?

If you use USB, you need to use a computer between them, as an NXT can't be a USB host. The same goes with I2C, you would have to use a uC between NXT's, as an NXT can't be an I2C slave.

Bluetooth on the NXT can be master or slave (maybe also peer-peer), so you don't need anything between NXTs to use it. RS485 is peer-peer, and can be programmed as master-slave, so it could also be used directly between NXTs.

Hi !

I do not know how to send and receive data via Bluetooth between two NXT. Hope anyone can help me
Veryone can send documents or code to me via mail : luupk.ceit@gmail.com
Thanks ALL !

Please help me.

He used the NXTBee (http://dexterindustries.com/NXTBee1.html ), but I'm not very experienced with that. This is his blog: http://www.ericsmalls.com/ . You could try asking him about it by leaving a comment on one of his projects; he has a lot more experience with this than I do.

Hi you !
Can you send to me the XBeeTools.h header file?

Thank so much !

Hi guys,

This topic deals with multi-robot communication.
Dexter Industries NXTBee utilizes Xbee radios and the NXT's high-speed RS-485 link (sensor port 4) to accomplish multi-robot communication. I've done a number of projects in this area.
