PC Send Bluetooth

[seb heliboles]

Hello,

I want to send a message with the pc to the NXT with your function void Bluetooth::send(unsigned char *buffer, unsigned int num_bytes) and I would like more details to use this for sending a message.
Sorry for my english, I’m french.

Hi this is for the C++ library…

Ok could you please post some code of what you are trying to do

I use this code

 #include <cstdlib>
    #include <iostream>
    #include <string>
    #include <conio.h>
    #include "nxt.h"

    using namespace std;

    Bluetooth *blue = new Bluetooth();
    int port ,erreur=0;
    int main()
    {

        try{
            cout << "Tentative de connexion" << endl;
            cout << "Selectionner le port" <<endl;
            while(erreur==0){
                try{

                    scanf("%d",&port);
                    blue->connect(port);
                    cout << "Connexion reussi" << endl;
                    erreur=1;
                }
                catch (Nxt_exception& e){
                    printf("- Port %d Erreur \n",port);
                }
            }

        }
        catch (Nxt_exception& e){
        //some error occurred - print it out
            cout << e.what() << endl;
            cout << "error code: " << e.error_code() << endl;
            cout << "error type: " << e.error_type() << endl;
            cout << e.who() << endl;
            return 0;
        }
        unsigned int b=2;
        unsigned char un[]={'0','a'};
        blue->send(&un[0],b);

}

Everything looks ok – but the command that you are sending does not make sense to the NXT firmware. Also be sure to close the connection when you are done. If you go to the documentation you can see the source code for some of the things that I implemented. You can find the documentation here

I do not understand what I have to write in the table to be understood by the nxt.
I have to use a procedure?
