Hi, I have a problem regarding Seeedstudio Bluetooth shield http://www.seeedstudio.com/depot/Bluetooth-Shield-p-866.html
I can't detect its presence by any other devices.
The code I uploaded to Arduino is a standard example for slave device from the library:
/* Upload this sketch into Seeeduino and press reset*/
#include <SoftwareSerial.h> //Software Serial Port
#define RxD 6
#define TxD 7
#define DEBUG_ENABLED 1
SoftwareSerial blueToothSerial(RxD,TxD);
void setup()
{
Serial.begin(9600);
pinMode(RxD, INPUT);
pinMode(TxD, OUTPUT);
setupBlueToothConnection();
}
void loop()
{
char recvChar;
while(1){
if(blueToothSerial.available()){//check if there's any data sent from the remote bluetooth shield
recvChar = blueToothSerial.read();
Serial.print(recvChar);
}
if(Serial.available()){//check if there's any data sent from the local serial terminal, you can add the other applications here
recvChar = Serial.read();
blueToothSerial.print(recvChar);
}
}
}
void setupBlueToothConnection()
{
blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
blueToothSerial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
blueToothSerial.print("\r\n+STNA=SeeedBTSlave\r\n"); //set the bluetooth name as "SeeedBTSlave"
blueToothSerial.print("\r\n+STOAUT=1\r\n"); // Permit Paired device to connect me
blueToothSerial.print("\r\n+STAUTO=0\r\n"); // Auto-connection should be forbidden here
delay(2000); // This delay is required.
blueToothSerial.print("\r\n+INQ=1\r\n"); //make the slave bluetooth inquirable
Serial.println("The slave bluetooth is inquirable!");
delay(2000); // This delay is required.
blueToothSerial.flush();
}
I've uploaded it to Arduino UNO, connected the shield and... Nothing. LED marked as D1 is blinking, and D2 is switched off. The device is not detected by none of the three devices I've tried (two computers and a smartphone).
I tried to connect it to other UNO board (in case the first one was damaged), but the result is the same.
I thought that the shield is somehow damaged, so I had it replaced by a new one - but the results are still the same.
Summing up:
- 3 extrnal devices
- 2 Arduinos
- 2 shields
Tested in all possible combinations, and still no success.
The device is powered up, because when I set it to send it's status to A1 analog port I always read 0 instead of a random value.
The only logical conclusion is that there is something wrong with the code above, but every google search I've made pointed me exactly to that file. It's on official wiki and in every example I've found. I've tried to contact Seeedstudio about it, but they didn't have anything of value to add ("try rebooting until it works").
Has anyone had similar problem, or has any advice how can I solve this problem?
