其实这个ISSUE在mpy库被提了好久了，不知道为啥，大约五天前突然被解决，也就是说，最新的主分支已经可以用gap_pair功能了，貌似还有个gap_passkey，现在mpy的ble功能终于补上最后一块了，遗憾的是目前还不能进行功率的控制。 github上有个mpy ble hid设备的库，也挺好的，用01studio的手柄我改了程序，能用，但是不能二次链接重连，自己想了半天也没明白，最后鼓起勇气在提了ISSUE，平生第一次提ISSUE，没想到过了一天被答复了，还让我有空测试下功能，感谢伟大的开源精神！ 说到开源，其实在国内前途很不好，有文化的原因，也有现实制度原因，国内的玩家更喜欢白嫖，不是批判谁也不是装清高，我是觉得大家是该有点贡献精神的，我虽然大多拿钱办事，但是也不忘贡献点力量，写写博客，偶尔提交点pr，国内主要是生存压力比较大，没有太多自己的时间玩爱好，都喜欢要现成的。我个人觉得01studio真的不如把库放在GITEE，说是开源项目，实际上也就是微信群聊，都搞了4个开源项目了，贡献者好像还是只有我一个，当然主要是老板送我板子我不好意思不贡献哈哈，能在群里唠唠项目提提意见就不错了，能会git操作的、有足够水平的、愿意贡献代码的，层层筛选下来太少了，当然还是有很多活跃用户在群里贡献了代码，只是不习惯GIT操作而已。 当ISSUE被解决时竟然有一丝丝感动，地球的另外一个角落的某个嵌入工程师不嫌弃我的蹩脚塑料英语，不限国家、肤色、生活习性方式，只为了解决同一个问题展开讨论，感觉真好，该死的是那些总夹带私货别有用心的人，污染了环境，想起列侬的imagine了，理想全世界的人无隔阂在一起，太过于美好，虽然知道不可能实现，也忍不住去想想那样一副画面。 拉回正题，搬运了一个ble hid的库，很有用：
