四、实验前提
1、在进行本文步骤前，请先
阅读以下博文：
1）《CC2541之SNV》：http://blog.csdn.net/feilusia/article/details/50190859
2）《
CC2541之添加特征值
》：
http://blog.csdn.net/feilusia/article/details/48235691
2、在进行本文步骤前，请先实现以下博文：
1）《CC2541之配对与绑定》：http://blog.csdn.net/feilusia/article/details/50212945
3）《CC2541之通信协议》：http://blog.csdn.net/feilusia/article/details/53520236
4）《CC2541之配对密码的读取与修改》：http://blog.csdn.net/feilusia/article/details/53609219
五、基础知识
1、为什么要密码重置？
答：我们通信时使用的UUID通道往往是加密的，一旦用户忘记密码，就会导致设备无法再连接上。
因此需要再增加一个无加密的UUID通道，作为密码重置通道。
本文使用0xfff7通道作为密码重置通道。
六、通信协议
七、测试指令
香瓜的测试指令
1、功能码0x00（开关灯）
1）关灯
fe010000ffffffffffffffffffffffffffffffff
2）开灯
fe01000100ffffffffffffffffffffffffffffff
2、功能码0x01（读取密码）
fe0001ffffffffffffffffffffffffffffffffff
3、功能码0x02（修改密码）
1）修改密码为654321
fe0402f1fb0900f9ffffffffffffffffffffffff
2）修改密码为132648
fe04022806020034ffffffffffffffffffffffff
4、功能码0x90（重置密码）
fe04900000000092ffffffffffffffffffffffff 八、实验步骤
1、新增0xfff7通道特征值
1）替换simpleGATTprofile.c

}九、注意事项
手机可能缓存了之前的代码（在更新过CC2541的代码之后，都需要清除手机端的缓存！！！），因此要清除缓存，清除缓存的方法如下：
方法一：关闭app、关闭蓝牙总开关、打开蓝牙总开关、打开app。
方法二：手机重启。
十、实验结果
仿真并全速运行工程，基于《CC2541之配对密码的读取与修改》的实验结果上（使用修改密码的指令修改设备密码之后），再使用另一台安卓手机连接CC2541，并点返回键跳过配对等待的状态，需要在几秒内向0xfff7通道发送
功能码0x90（重置密码）
fe04900000000092ffffffffffffffffffffffff
发送重置密码指令与应答过程如下图：
重置密码过程如下图：
因此，跳过配对过程并将密码重置成功，实验成功。
