Introduction

Bluetooth 4.0 HM-10 Master Slave Module use TI CC2541, Master and slave roles in one, transmission version and remote control version and PIO state acquisition functions in one, Support the AT command modify module parameters, Convenient and flexible.
Transmission version can be used to transmit data between two Bluetooth devices.
Remote Control version can be used to Control PIO ports output high or low level without any other MCU.
PIO state acquisition version can be used to acquisition PIO ports state without any other MUC. (Only support Bluetooth V2.1)

Physical Dimension: 27mm x 13mm x 2.2 mm.

Pin Description:

STATE: state test pins, connected to internal LED, generally keep it unconnected.
BRK: break connect, it means breaking Bluetooth connection, generally keep it unconnected.
VCC: positive pole of the power source.
GND: Ground.
TXD: serial interface, transmitting terminal.
RXD: serial interface, receiving terminal.

Test method

Using SunFounder Uno

Step 1: You should compile and upload the code before building the circuit

/****************************************/
#define ledPin 13  // //pin 13 built-in LED light
int val;
void setup()
{
  Serial.begin(9600);
  pinMode(ledPin, OUTPUT);
}
void loop()
{
  if(Serial.available()) //
  {
    val = Serial.read();
    if(val =='A')  //if comes a 'A',LED on control board will blink
    {
      digitalWrite(ledPin, HIGH);
      delay(500);
      digitalWrite(ledPin, LOW);
      delay(500);
      Serial.println("Rebecca");  //print on Serial debugging assistant on computer
    }
  }
}
/****************************************/

Step2: Connecting circuit

Step 3: You need to download a Bluetooth 4.0 debugging assistant for mobile phone to connect your phone with the Bluetooth4.0 module. We've provided the tool in Android. Just download BleSerialPort.zip on your smart phone and decompress. Then you can see a file BleSerialPort. Enable Bluetooth on your phone and install the BleSerialPort.

After connecting mobile phone or other Bluetooth device and Bluetooth-4.0 module successfully (Fig 4), the LED indicator on the Bluetooth module will be steady on (stop blinking). Otherwise, the LED indicator will keep blinking.
Now you can send commands. Send a character A to the Bluetooth-4.0 module. If the communication works normally, on the surface you can see A sent out and Rebecca returned. Then the LED on the SunFounder UNO board will blink once.

Using AT Commands

Step 1: wire.
Connect TXD of Bluetooth 4.0 Module to RXD of PL2303, RXD to TXD, GND to GND, and VCC to VCC. PL2303 is a USB to Serial Bridge Controller. You can also use other components, such as FTDI.

VCC VCC
GND GND
TXD RX0(pin0)
RXD TX0(pin1)

Step 2':set parameters
After wiring, open the serial port debug tool sscom32. Set parameters at first.
1) Open the serial port, click Open Com. Select the correct port, as shown below.
COM0321.png
2) Select the correct baud rate. Here select 9600 bps.Default: 9600, as shown below.

Step3: Now, you can start to send instructions. Enter”AT” in the text box. If Bluetooth 4.0 Module goes well, OK will be sent, as shown below:
AT.png Also you can send AT+NAME?. OK+NAME:HMSoft will be returned .

Send AT+BAUD?, OK+Get:0 will be returned. Default: 0(9600)
