hi,

I need to make NXT communicate by bluetooth with my PC.
I want to use RobotRealm to find and approach a blue ball, but using robotc software for robot navigation. So, I need to enable messaging between NXT and PC, and when robotrealm sees a blue ball it can send a message to NXT and take control of it, or viceversa.

Anyway, I couldn't find any information about messaging in the software. Is it possible?

or, may be, some one can explain me why BT Sample Program does not work...

I have perfect BT connection between pc and nxt (download, poll brick, etc.).
Simply, I have an overflow during ConnectPort() and a freez during SetBrickName()

thanks

so...

no one tried to use bt messaging to make communicate NXT and PC...

I'm not able to resolve this problem alone...

There are some problems with current RobotC Bluetooth messaging. I hope to have them resolved soon.

THe first target is to ensure NXT-to-NXT messaging is work. Yours is a broader problem of NXT-to-PC where the PC is running a user application and not the RobotC environment. FOr this, the PC will have to behave (i.e. message) exactly like a NXT. This will require a relatively high level of technical expertise and programming experience.

What is your technical skill set and background? I am unfamiliar with the Robot Realm environment.

There are a number of toolkits that have been developed to facilitate communications between a PC application program and a NXT over BT. Are you familiar with these and have you selected one? Which one?

Any idea when a release with NXT to NXT messaging might become available?

task main()
{

TFileIOResult result;
btConnect(result,8,"R_RIGHT");

nxtDisplayTextLine(2,"%s",result);
wait1Msec(100);
motor[motorA]=1000;

wait1Msec(100);
motor[motorA]=0;

btDisconnect(result,8);

}

BT NXT-to-NXT messaging will be available in the next pre-release (version 1.10).
