Model Number: MD0372

    Duinofun BLE Shield v1.0 is a low -power Bluetooth 4.0 transmission module. Module uses a TI CC2540 chip configuration 256Kb space, support AT commands. You can use this module is used in remote , game controller , wireless data collection, smart home and other fields. At the same time as the Shield series one , it is very convenient to use the ne to the development board .     Parameter

Size : 68mm x 43mm       Product Features

HM-11: We use low-power Bluetooth module HM-11 module , please cck on the nk to enter the HM-11 wiki conducted inspection.
Signal lamp: State of connection indicator , when not connected to the frequency of about one second for each indicator flashes ; When nked , indicator ght .
Puzzle connectors: Duinofun BLE Shield v1 Puzzle board has two interfaces , user-friendly product ne Puzzle .
Hard or Softserial port: Users can select different port as a transfer port numbers to jump through this cap . Reserved pinouts from HM-11: These primers export reserved pins on the module HM-11, when the user needs can be very rapid welding , for ease of use .
Reset button: reset button, press to reset the HM-11 module. And press the reset button Duinofun BLE Shield does not affect the status of the development board .     BLE Shield directly inserted into the Ardui-no. Please note that the PCB jumper cap choice.       Soft serial communication

When you use a different code , Duinofun BLE Shield can be used as master or slave . When using the soft serial communication, namely the use of software code to communicate BLE module , jumper cap should be chosen as : BLE_TX -> D2, BLE_RX -> D3.
Then open the Ardui-no IDE v1.0.5, copy the following master or slave code and download it to the motherboard .         Master-Slave code #include <SoftwareSerial.h> //Software Serial Port
#define RxD 2
#define TxD 3 #define DEBUG_ENABLED 1 SoftwareSerial BLE(RxD,TxD); void setup()
{
Serial.begin(9600);
pinMode(RxD, INPUT);
pinMode(TxD, OUTPUT);
setupBleConnection(); } void loop()
{
char recvChar;
while(1){
if(BLE.available()){//check if there's any data sent from the remote BLE shield
recvChar = BLE.read();
Serial.print(recvChar);
}
if(Serial.available()){//check if there's any data sent from the local serial terminal, you can add the other appcations here
recvChar = Serial.read();
BLE.print(recvChar);
}
}
} void setupBleConnection()
{
BLE.begin(9600); //Set BLE BaudRate to default baud rate 9600
BLE.print("AT+CLEAR"); //clear all previous setting
BLE.print("AT+ROLE0"); //set the bluetooth name as a slaver
BLE.print("AT+SAVE1"); //don't save the connect information
}
Master Code:
#include <SoftwareSerial.h> //Software Serial Port
#define RxD 2
#define TxD 3 #define DEBUG_ENABLED 1 SoftwareSerial BLE(RxD,TxD); void setup()
{
Serial.begin(9600);
pinMode(RxD, INPUT);
pinMode(TxD, OUTPUT);
setupBleConnection(); } void loop()
{
char recvChar;
while(1){
if(BLE.available()){//check if there's any data sent from the remote BLE shield
recvChar = BLE.read();
Serial.print(recvChar);
}
if(Serial.available()){//check if there's any data sent from the local serial terminal, you can add the other appcations here
recvChar = Serial.read();
BLE.print(recvChar);
}
}
} void setupBleConnection()
{
BLE.begin(9600); //Set BLE BaudRate to default baud rate 9600
BLE.print("AT+CLEAR"); //clear all previous setting
BLE.print("AT+ROLE1"); //set the bluetooth name as a master
BLE.print("AT+SAVE1"); //don't save the connect information
}     Hard serial communication

Of course, you can operate directly on the BLE module via AT commands , without using any code. But note jumper cap position : BLE_TX -> D1, BLE_RX -> D2.
Then open the serial port tools, such as MAC Edition users can open CoolTerm assistant serial , PC users can open Sscom32 serial version of the tool . Set serial instruments are as follows : Baudrate: 9600 (default), Data Bits: 8, Parity: none, Stop Bits: 1 You can send commands "AT" test , if the return "OK", i.e., can communicate. If you do not return any values, the user can try to burn an empty program to the motherboard , and then send the command "AT" for testing.     void setup()
{
} void loop()
{
}       After confirmation you can communicate , you can send AT commands to the BLE module . Such as setting BLE module from the machine , sending commands "AT + ROLE0", if it returns "OK + Set: 0", it means that BLE module has been successfully set .     E3D V6 3D Print J-head hotend &Single Coong Fan for 1.75mm/3mm Direct Filament Wade Extruder 0.3/0.4/0.5mm Nozzle longdistanceUSD 8.23/piece1.75MM Upgrade MK8 Extruder Nozzle Extruder Print Head for 3D Printer,Makerbot,Prusa i3,with Extra Throat Tube + Nozzle for freeUSD 26.86/pieceJhead J-head Hotend for 1.75mm/3.0mm Bowden Extruder 0.2mm/0.3mm/0.4mm long or short distance feeder OptionalUSD 4.99/piece3D Printer E3D V5 J-head Hotend for 1.75mm/3.0mm 3D Bowden Extruder 0.3mm/0.4mm/0.5mm Nozzle OptionalUSD 8.23/pieceRepRap 3D Printer MK4 MKIV J-Head Hot End 0.3mm nozzle 1.75mm filamnetUSD 16.78/piece1 Set 3D printer heating aluminum block with Thermistor with copper sleeve improved Speically used for Makerbot MK7 MK8 ExtruderUSD 6.17/set1 set MK8 extruder aluminum block DIY kit Makerbot dedicated single nozzle extrusion head aluminum block extruder MK8 extruder USD 5.01/setImproved Version Printer Parts Reprap Makerbot MK8 Full Metal Aluminum Alloy Bowden Extruder for 1.75MM Filament MK8 Extruder USD 21.37/piece       http://g004.s.acdn.com/kf/HTB1RPi5FXXXXXXudXXXq6xXFXXXk/206203646/HTB1RPi5FXXXXXXudXXXq6xXFXXXk.jpg?size=186486&;
