蓝牙HID键盘源代码，采用CSRBLUELAB27架构有很好的参考价值和开发价值。-Bluetooth HID keyboard source code, adopted CSRBLUELAB27 structure is a good reference value and development value.

Dialog’s Bluetooth Smart wireless keyboard reference design is built on its world-leading DA14580 Bluetooth Smart chip and takes advantages of the chip’s capabilities to push the boundaries of wireless keyboard battery lifetime longevity and Bill of Materials (BoM). The reference design includes all necessary hardware, software and documentation to design a keyboard guaranteeing fastest time-to-market with minimal development investment and effort.
The software is provided in source code and offers all of the flexibility to customize the keyboard and wireless connection parameters according to your application’s needs. Features 109-key keyboard with numeric keypad and function keys 2 LEDs for connection status and low battery indication Lowest BoM Powers from a single AAA alkaline or NiMH battery Minimal external component count with only 16 passive components required for the complete keyboard system Double the battery lifetime of current available solutions with less than 5 mA peak current consumption in active mode and less than 600 nA in stand-by Programmable connection interval and slave latency Multi-key press detection 6-key simultaneous press reporting De-ghosting (for multiple key combinations) Wake-up from deep sleep with any key press Supports connection to multiple hosts Programmable deep sleep entry time All key parameters are SW customizable Interoperability with all major operating systems: Win 8.1, iOS7 and Android 4.3 and beyond WHQL certifiable

Logitech K380蓝牙键盘，默认最顶上一排键是各种快捷功能。用Logitech的软件可以改成默认F1~F12。但是为了改个Fn键，装200M软件也太那什么了。 此程序可用VC编译，在Windows下运行，找到K380键盘后，写入相应的指令，打开Fn锁定功能，最顶上一排键默认为F1~F12。 每次开关、重新连接键盘后，需重新运行此程序。如果想关闭Fn lock，可以发送程序中带的k380_seq_fkeys_off数据串给键盘。更简单的办法是关掉再打开。 此程序原本是劫持条码扫描枪用的。前面查找HID设备名的功能都一样。后面发送指令的功能是从： https://github.com/jergusg/k380-function-keys-conf 这里抠出来的。
