ein Bluetoothproblem

hallo,

hast Du versucht Dein text-sende-code:

Code:

/*Dieser Code gehört zu dem Video auf Youtube


https://www.youtube.com/watch?v=WbGwszuN6ww
mit Verbindung über Rx und Tx  */


int led = 13;
void setup()
{
  Serial.begin(9600);
 
  pinMode(led,OUTPUT);
  digitalWrite(led,LOW);
}
void loop()
{
 if(Serial.available())
 {
   String value = Serial.readStringUntil('\n');
   Serial.println(value);
   if(value == "on")
   {
     digitalWrite(led,HIGH);
   }
   else if(value == "off")
   {
     digitalWrite(led,LOW);
   }
 }
}

in den code - der mit der ardroid app zusammenarbeitet - zu integrieren?

Dies Frage verstehe ich leider nicht.

Meine Erfahrungen mit BT z.Z.

HC06 funktioniert prima. HC05 wenn die Verbindung einmal steht i.O.. Bis es soweit ist, muss ich aber immer mehrer Anläufe nehmen. Manchmal hatte ich sogar den Eindruck, dass er defekt sei, weil die LED weder leuchtete noch blinkte. Dann gings aber plötzlich wieder.

nunja, es ging mir darum, ob Du versucht hast aus diesem code:

Code:

/*
 PROJECT: Ardroid

*/




#define START_CMD_CHAR '*'
#define END_CMD_CHAR '#'
#define DIV_CMD_CHAR '|'
#define CMD_DIGITALWRITE 10
#define CMD_ANALOGWRITE 11
#define CMD_TEXT 12
#define CMD_READ_ARDROID 13
#define MAX_COMMAND 20  
#define MIN_COMMAND 10  
#define IN_STRING_LENGHT 40
#define MAX_ANALOGWRITE 255
#define PIN_HIGH 3
#define PIN_LOW 2




String inText;




void setup() {
  Serial.begin(9600);
  Serial.println("Ardroid By : Anurag Goel");
  Serial.flush();
}




void loop()
{
  Serial.flush();
  int ard_command = 0;
  int pin_num = 0;
  int pin_value = 0;




  char get_char = ' ';  //read serial




  // wait for incoming data
  if (Serial.available() < 1) return; // if serial empty, return to loop().




  // parse incoming command start flag 
  get_char = Serial.read();
  if (get_char != START_CMD_CHAR) return; // if no command start flag, return to loop().




  // parse incoming command type
  ard_command = Serial.parseInt(); // read the command
  // parse incoming pin# and value  
  pin_num = Serial.parseInt(); // read the pin
  pin_value = Serial.parseInt();  // read the value
  // 1) GET TEXT COMMAND FROM ARDROID
  if (ard_command == CMD_TEXT){   
    inText =""; //clears variable for new input   
    while (Serial.available())  {
   char c = Serial.read();
  
     //gets one byte from serial buffer
      delay(5);
      if (c == END_CMD_CHAR) { // if we the complete string has been read
        // add your code here
        Serial.println(inText);
        break;
      }              
      else {
        if (c !=  DIV_CMD_CHAR) {
          inText += c; 
          delay(5);
        }
      }
    }
  }




  // 2) GET digitalWrite DATA FROM ARDROID
  if (ard_command == CMD_DIGITALWRITE){  
    if (pin_value == PIN_LOW) pin_value = LOW;
    else if (pin_value == PIN_HIGH) pin_value = HIGH;
    else return; // error in pin value. return. 
    set_digitalwrite( pin_num,  pin_value);  
    return;  // return from start of loop()
  }




  // 3) GET analogWrite DATA FROM ARDROID
  if (ard_command == CMD_ANALOGWRITE) {  
    analogWrite(  pin_num, pin_value ); 
    // add your code here
    return;  // Done. return to loop();
  }




  // 4) SEND DATA TO ARDROID
  if (ard_command == CMD_READ_ARDROID) { 
    // char send_to_android[] = "Place your text here." ;
    // Serial.println(send_to_android);   // Example: Sending text
    Serial.print(" Analog 0 = "); 
    Serial.println(analogRead(A0));  // Example: Read and send Analog pin value to Arduino
    return;  // Done. return to loop();
  }
}




// 2a) select the requested pin# for DigitalWrite action
void set_digitalwrite(int pin_num, int pin_value)
{
  switch (pin_num) {
  case 13:
    pinMode(13, OUTPUT);

    digitalWrite(2, pin_value); 
    // add your code here       
    break;      
  
  } 
}

und dem code aus meinem letzten post eines zu machen, welches für analogWrite, digitalWrite und data mit der app ardroid funktioniert?
Anders gefragt: Du wolltest doch damit Deinen Bagger steuern. Verwendest Du analg-, digital- oder das DATA- teil des codes und der app?
