This is the JUMA.IO implementation for STM32 embedded platform. It includes a comprehensive SDK to facilitate development work for BLE communication and typical Wireless Sensor Applications.

##Hardware Support

###Cannon 小钢炮

Cannon board consists of a powerful MCU, a BLE transmitter(BlueNRG-MS), and several MEMS sensors. All the software resources of this repository can run on it, Both hardware and software are open-sourced, making it an ideal platform for learning or developping BLE/IoT applications.

##Quick Start

Environment: Windows7, Keil, Cannon board.

1. Choose Demo project Learn demos under ./applications folder, select and open one project(*.uvprojx) in Keil.

2. Compile
   Use build command to compile the project.

3. Download firmware
   Connect Cannon to computer via J-Link or ST-LINK. Download firmware to Cannon.

4. Work with BLE APP
   A debugger APP (./tools/JumaBleHelper.apk) is offered to facilitate BLE development. It can be installed and run on Android machine to transmit BLE raw data to/from Cannon.
   The iOS version can be downloaded in AppStore as well.
