ESP8266 SSL MQTT 双向认证开发记录（已OK）
1.因为RTOSSDK有更新，所以采用这个SDK
用esp-mqtt来进行操作
例程地址：ESP8266_RTOS_SDK\examples\protocols\mqtt\ssl_mutual_auth
(1) . 这里所谓双向验证，其实只需要用户的PEM和KEY就行了 这里PEM可以是CRT格式，一样的
注意，不需要加服务器的CA，这个没吊用的
注意官方demo常常返回0x50错误，是 验证hello时出错，多连几次就行，如果是其他的国内服务器，应该不会有这个问题
(2).若要单向认证，参考ESP8266_RTOS_SDK\examples\protocols\mqtt\ssl即可
官方demo地址可用
对应的连接方式为下图这种方式
2.需要注意，RTOS的SDK有坑，freertos改一下定时器heap ，防止程序上电就死机。。。我这样改可以，不纠结了，可能还有其他方法
3.demo里面，可以看readme，将自己用open ssl 生成的csr发网上地址，请求一个crt回来，然后写进去文件就行。
这里文件其实是cmake.txt里面将文件搞成bin了
我们这里直接定义在程序里面，搞个const就行
程序配置如下：
(1).client_id 设置一下 某些平台限制了id和nam password 要对应的 否则登录不了
(2).name password 看情况
(3).task_stack 其实就是mqtt主任务的栈，可以设大一点，看情况吧
(4). keepalive是心跳的时间，看着来
发心跳有如下提示，若开了比较低的log
注意这里有个坑，host和port不需要填，只需要填url就行
这里的mqtt: mqtts: 对应你用什么方式去认证，后面 的 才是真正的地址
pem不需要自己设长度，里面会直接strlen帮算了
开了log为最低后，可以看到很多信息，我这里将SSL的认证流程打出来了
在ssl_tls.c里面
若要看到更详细信息，可以打开mbedtls的打印看
所有的STEP在这
关于ERROR，如果是mbedtls的，其实可以在mbedtls的库里面error.c进行搜索 看看对应是什么值，这样再搜这个值对应在哪里return就行
