The Bluetooth Shield integrates a Serial Bluetooth module. It can be easily used with Arduino/Seeedstudio for transparent wireless serial communication. You can choose two pins from Arduino D0 to D7 as Software Serial Ports to communicate with Bluetooth Shield (D0 and D1 is Hardware Serial Port). The shield also has two Grove connectors (one is Digital, the other is Analog) for you to install Grove modules.
Features
Seeeduino/Arduino compatible
Up to10m communication distance in house without obstacle
UART interface (TTL) with programmable baud rate (SPP firmware installed)
Default baud rate: 38400, data bits: 8, stop bit: 1, Parity: No parity
Default PINCODE:”0000”
A full set of configuration commands
On board PCB antenna
FCC ID certificated

115200 baud with Bluetooth Shield over Hardware Serial
I have been trying to get the bluetooth shield to run at 115200 baud and cannot get it to work. I am using hardware serial ports to communicate with the shield and program the Uno using the AVR in system programmer. I have gotten it to work at 38400 baud just fine but when I change the Serial.begin(115200) rather than Serial.begin(38400) it fails to make the shield inquirable. Code below.
void setup()
{
Serial.begin(115200);
Serial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
Serial.print("\r\n+STNA=SeeedBTSlave\r\n"); //set the bluetooth name as "SeeedBTSlave"
Serial.print("\r\n+STOAUT=1\r\n");
Serial.print("\r\n+STAUTO=0\r\n");
delay(2000);
Serial.print("\r\n+INQ=1\r\n");
//Serial.println("The slave bluetooth is inquirable!");
delay(2000);
Serial.flush();
}
Hello,
I use a Arduino Mega, throw the Serial3 (And It works).
I need to increase the baud rate (_ 38600). I tried to send the right command, but nothing change...
What should I do ?
How to proceed ?
Hi.If you use Mega with bluetooth,you may modify your code:#define RxD 11;
#define TxD 12.And connect digital 6(7) to digital 11(12) via jumper wire.
