Microduino-Shield BT4.0 Microduino-Shiedl BT4.0 module is a plug-in device that supports Bluetooth 4.0 low energy standard. Microduino-Shield BT4.0 module is a bluetooth serial port transparent transmission module, use the 27 PIN standard Microduino interface, support the Arduino board and derivatives, such as Microduino core. The module is designed by player ogre_c. Features Microduino-Shield BT4.0 use U type 27 PIN interface of Microduino, combines with other Microduino modult to use; Microduino-Shield BT4.0 use the HM-10 BLE as the bluetooth core module; TI CC2540 chip with 256Kb space; Support AT command，the serial baud rate, device name, matched passward can be changed, easy to use； Small, cheap, stackable, opened platfrom; Open source hardware circuit design, compatible with the Arduino IDE development environment for programming; Defines unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly. 2.54 pitch row female connector for easy integration into breadboard. Specifications Communication forms: serial passthrough; Power：+3.3VDC 50mA； Bluetooth protocol：Bluetooth Specification V4.0 BLE； Service：Central & Peripheral UUID FFE0,FFE1； Working frequency：2.4GHz ISM band； Modulation method：GFSK(Gaussian Frequency Shift Keying)； Transmission power：≤4dBm； Sensitivity：≤-84dBm at 0.1% BER； Transmission rate： Asynchronous: 6 kbps； Synchronous: 6 kbps； State indicator： Two states： Flashing means module powered, no matched. Lighting means module has matched and can start communication. You can know the module's state by the indicator, easy to use.

Use PC to debug Use serial directly： No need superimpose the FT232 directly, cross connect the FT232 and Shield BT4.0's RX0,TX1. Use FT232R、Core download and debug Use default jumper (RX0、TX1)： Unplug the Microduino Shield BT4.0 during download program; If you want to change the jumper cables to meet your requirement：cut the connection between two intermediate of the pad and RX0/TX1, and then connect them to D2, D3(or D9、D10). If changed the jumper, need the change the serial connection between Microduino Shield BT4.0 and Core module, change the connection "TX-RX0、RX-TX1" to following: TX-D2、RX-D3 (For Core+'s Serial1) TX-D9、RX-D10 (all SoftwareSeria libray to resolve) Pin description 文件:BT-Pinout-1.jpg Microduino-BT-Pinout-t 文件:BT-Pinout-2.jpg Microduino-BT-Pinout-b HM-10 Pin Microduino Pin Function TX RX0（orD2/D9） serial send pin (TTL)，connect Core's RXD RX TX1（orD3/D10） serial receive pin (TTL)，connect Core's TXD Support AT command to configure and control：文件:Bluetooth40 cn.pdf，文件:Bluetooth40 en.pdf Application Download progrm Test program：文件:BLE debug uart1.zip,文件: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 (1.0 release and upper), Microduino test program (Arduino part), download LightBlue from App Store； Start Arduino IED，open the Microduino test program, board type select "Microduino Core (Atmega328P@16M,5V)", download directly； Start to set the IOS device： start the bluetooth function on IOS device； Open LightBlue； In "Central" tab find the "HMSoft", then set "Service"-"Characteristics"; Then you can see the debugging window, click the "Start Notify". ASCII data can be seen displayed: "BLE, Time: xxx" after connection success, where xxx is the Core and Shield BT4.0's running time in seconds. Use Core+'s uart1 to debug Shield BT4.0 Prepared hardware：Microduino FT232R, Microduino Core+, Microduino Shield BT4.0； Prepared software：Arduino IDE (1.0 release and upper), Microduino test program (Arduino part)； Other configuration：Suppose the player has changed the jumper which change the serial to D2、D3； Start Arduino IED, open Microduino test program, select the board type "Microduino Core (Atmega328P@16M,5V)", download directly； Check the serial communication： Open the serial monitor,send uppercase “AT”(no \r\n appened), if return “OK”，that means matched. Microduino-Shield BT4.0 simple testing Microduino-Shield BT4.0 simple testing from @颜火山 Bug 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.
