Microduino-Shield BT 4.0 module is a plug-in device that supports Bluetooth 4.0 low energy standard.
Microduino-Shield BT 4.0 module is a bluetooth serial port transparent transmission module, using the 27 PIN standard Microduino interface, supporting the Arduino board and derivatives, such as Microduino core.
The module is designed by player ogre_c.

==Features==
*Microduino-Shield BT4.0 adopts U type 27 PIN interface of Microduino, combining with other Microduino modult to use;
*Microduino-Shield BT4.0 chooses the HM-10 BLE as the bluetooth core module;
*TI CC2540 chip with 256Kb space;
*Support AT instruction, capable of updating baud rate, device name,paring code and other related parameters as needed, flexible to use；
*Small, cheap, stackable;
*Open source hardware circuit design, compatible with the Arduino IDE development environment for programming;
*With uniformed Microduino interface standard and rich peripheral modules, it is flexible and convenient to have a quick connection and extension with other corresponding Microduino modules and sensors;
*2.54 pitch row female connector for easy integration into breadboard.

==Specifications==
*Communication form: serial transmission;
*Power supply：+3.3VDC 50mA；
*Bluetooth protocol：Bluetooth Specification V4.0 BLE；
*Service support：Central & Peripheral UUID FFE0,FFE1；
*Frequency：2.4GHz ISM band；
*Modulation mode：GFSK(Gaussian Frequency Shift Keying)；

*Transmission rate：
**Asynchronous: 6 kbps；
**Synchronous: 6 kbps；
*State indicator：
**Two states：
***Flashing means that the module has been powered but not matched well.
***Always lighting means that the module has been matched well and has started communication.
**By the indicator, it is very easy to the status of the module, which is conveniently.

==Development==
===Serial communication requirements===
*Default serial configuration：
**Baud rate: 9600
**No check
**Data bits: 8
**Stop bit: 1
*As for Arduino IDE serial monitor：
**Set at："No line terminator"、"9600baud"
*For other serial debug software：
**Baud rate: 9600
**No check
**Data bits: 8
**Stop bit: 1

*We suggest using Microduino-Core32u4 to debug this BT module:
**Microduino-Core32u4 module can use the USB to simulate the serial 0, and BT uses the 32u4's serial 1 (RX0,TX1), so you don't need to change the existing jumper (RX0,TX1) and it won't impact program download or the serial port's function.

*Microduino Shield BT4.0 uses the default serial RX0,TX1 to communicate with Core module, so it can be directly connected with Microduino FT232.

===Use PC to debug===
*When debugging directly through the serial port：
**No need to stack the FT232 directly, and just cross connect the FT232 and BT4.0's RX0,TX1.

===Use FT232R、Core to download and debug===
*If it keeps using the default jumper (RX0、TX1)：
**Unplug the Microduino Shield BT4.0 during downloading the program;
*If you want to change the jumper cables to meet your requirement, you need to cut the connection between two intermediate of the pad and RX0/TX1, and then connect them to D2, D3(or D9、D10).
**If it needs to change the jumper, you can change the serial connection of Microduino Shield BT4.0 and Microduino Core from "TX-RX0、RX-TX1" to:
***TX-D2、RX-D3 (For Core+'s Serial1)
***TX-D9、RX-D10 (you can adopt SoftwareSeria libray to solve the problem)

==Application==
===Download progrm===
Program test：'''[[File:BLE debug uart1.zip]]''','''[[File:BLE LightBlue time.zip]]'''

===Shield BT4.0 pass-through data to IOS devices===
*Prepared hardware：Microduino FT232R, Microduino Core, Microduino Shield BT4.0, supported Bluetooth 4.0 devices (iPhone4s upper,iPod touch 5 upper,iPad 3 upper,iPad mini upper)；
*Prepared software: Arduino IDE (version 1.0 or higher), Microduino test program (Arduino part) and LightBlue downloaded from App Store；
*Start Arduino IED，open the Microduino test program, select board "Microduino Core (Atmega328P@16M,5V)" and then download directly；
*Start to set the IOS device：
**start Bluetooth on IOS device；
**Open LightBlue；
**Find the "HMSoft" in "Central" tab , then set "Service"-"Characteristics" in order;
**You can see the debugging window and then click the "Start Notify".
*ASCII data can be seen to be displayed: "BLE, Time: xxx". Besides, xxx shows the runtime of Microduino-Core and Shield BT4.0's in seconds.

===Use Core32u4 to debug Shield BT4.0===
*Hardware needed：Microduino FT232R,Microduino Core 32u4 and Microduino Shield BT4.0;
*Software needed：Arduino IDE（version 1.0 or higher）, Microduino test program（Arduino part）;
**（You can keep the current jumper(RXO,TX1) without change for Microduino-CoreUSb utilizes USB simulation port 0(Serial) and the RXO and TX1 of Microduino-BT are the serial1 of Microduino-CoreUSB；
*Start Arduino IED, open Microduino test program, select Microduino-CoreUSB and then download;
*Check whether the serial communication is ok:
**Send the capitalized "AT"(NO \r\n after it) after opening the corresponding serial monitor. And if the return shows "OK", it means the setup is successful.

===Use Core+'s uart1 to debug Shield BT4.0===
*Hardware needed：Microduino FT232R, Microduino Core+ and Microduino Shield BT4.0；
*Software needed：Arduino IDE (version 1.0 or higher), Microduino test program (Arduino part)；
*Other condition：The player has changed the jumper, making the serial changed to D2、D3；
*Start Arduino IED, open Microduino test program, select the board type "Microduino Core (Atmega328P@16M,5V)" and then download directly；
*Check the serial communication：
**Open the serial monitor,send the capitalized “AT”( without \r\n behind), if the return shows“OK”，that means a successful configuration.

===Note：If you use Android device to debug, you need to make sure the system should be version 4.3 or higher so that Microduino-BT can be detected.===

===A simple test of Microduino-Shield BT4.0===
*[http://viewc.com/p/296 A simple test of Microduino-Shield BT4.0] from @颜火山

==FQA==
*This module can’t make pair with win7?
**Check the BT version in win7, this module only support BLE 4.0 version and default password is 000000.
*Does this module can reset by button?
**No, it can be reset by power down.
*This module can’t make pair with iphone and Android phone?
**This issue mostly is caused by the BT version. This module only supports BT4.0 protocol.
**For Andriod OS: 4.3 release
**For IOS: iPhone4s upper, iPod touch 5 upper, iPad 3 upper and iPad mini upper
==Buy==

==History==
*On June 5, 2013, the second time proofing is completed, changed its name to the "Microduino - (BT)" and added the third optional serial port - UART1, divided into 2 version, version 2.1, a module used for HM09;A 4.0 version, module used for HM10.
*On May 10, 2013, the board is completed.
