  • Connecting "stuff" via Bluetooth / Android / Arduino 3 months ago

    Arduino "language" is closer to C++

  • Connecting "stuff" via Bluetooth / Android / Arduino 3 months ago

    ;-) OK. Only I thought that I could explain better in Portuguese. Anyway, I try send you an explanation above. But maybe is better if you follow a C++ explanation about strings/char and how they are build.

  • Connecting "stuff" via Bluetooth / Android / Arduino 3 months ago

    The bellow function is the one responsible to create the command string.
    while (BT.available()) //Check if there is an available byte to read
    {
    delay(10); //Delay added to make thing stable
    char c = BT.read(); //Conduct a serial read
    device += c; //build the string.
    }

    The BT.read() will read character by character, its the way that it was build inside the library. That's because you must use "char c" to receive the data. The BT device will send 7 characters, so, during the time that the BT.available() is TRUE (look the while), you must "store" each character on the string command. You do it with the line: device +=c;

    When you enter in the above function, command must be empty. So you can load it with a fresh command.

    What is your mother language? Portuguese?
