Amarino bluetooth通訊問題

iron

請教版上各位前輩目前在用android開發版接藍牙裝置溝通arduino,
我的arduino bluetooth模組為DF-BluetoothV3
我用arduino MultiColorLampTutorial下去執行發現
void blue(byte flag, byte numOfValues)
{
  analogWrite(blueLed, meetAndroid.getInt());
}

不管我android那邊怎麼調這個callback就是不會執行
有確定android有偵測到arduino

懇請版上前輩不吝指教,我的baud rate有試過115200和57600


謝謝

可以把全部的程式貼上來嗎?

arduino的code
#include <MeetAndroid.h>

// declare MeetAndroid so that you can call functions with it
MeetAndroid meetAndroid;

// we need 3 PWM pins to control the leds
int redLed = 9;   
int greenLed = 10;
int blueLed = 11;
char val;

void setup()  
{
  // use the baud rate your bluetooth module is configured to
  // not all baud rates are working well, i.e. ATMEGA168 works best with 57600
  Serial.begin(57600);
  
  // register callback functions, which will be called when an associated event occurs.
  meetAndroid.registerFunction(red, 'o');
  meetAndroid.registerFunction(green, 'p');  
  meetAndroid.registerFunction(blue, 'q');

  // set all color leds as output pins
  pinMode(redLed, OUTPUT);
  pinMode(greenLed, OUTPUT);
  pinMode(blueLed, OUTPUT);
  
  // just set all leds to high so that we see they are working well
  digitalWrite(redLed, HIGH);
  digitalWrite(greenLed, HIGH);
  digitalWrite(blueLed, HIGH);

}

void loop()
{
  meetAndroid.receive(); // you need to keep this in your loop() to receive events
}

/*
* Whenever the multicolor lamp app changes the red value
* this function will be called
*/
void red(byte flag, byte numOfValues)
{
  Serial.print("red~~~\n");
  Serial.print(meetAndroid.getInt());
  analogWrite(redLed, meetAndroid.getInt());
}

/*

void red(byte flag, byte numOfValues)
{
  Serial.print("red~~~\n");
  Serial.print(meetAndroid.getInt());
  analogWrite(redLed, meetAndroid.getInt());
}

我就是這個callback沒呼叫到

回復 6# iron


    try this way:

void red(byte flag, byte numOfValues)
{
int orient_val;
  orient_val = meetAndroid.getInt();
Serial.print("red~~~\n");
  Serial.print(orient_val);
   analogWrite(redLed, orient_val);
}
================
你的android開發版是哪家哪一型的?
接 藍牙裝置是哪家哪一型的?

感謝vegewell大回覆
問題解決了
是baud rate要設成9600
謝謝v大

請問各位前輩:
我也做MultiColorLampTutorial,
一切都正常,
但在Run As Android Application後,
手機顯示"異常終止", 請問該如何解決?
詳細過程請到 http://www.robofun.net/forum/viewthread.php?tid=7747&extra=page%3D1

問題已解決!!
