esp8266关闭加密通信获得更多可用RAM

奈何col

blinker默认使用加密方式进行远程通信，但通信加密会消耗大量的RAM，如果您对通信安全性无要求，可以添加宏BLINKER_WITHOUT_SSL用以获得更多可用RAM

1. #define BLINKER_WIFI  
   
2. #define BLINKER_WITHOUT_SSL
   
3. #include <Blinker.h>  
   
4.   
   
5. void setup() {  
   
6.     Blinker.begin(auth, ssid, pswd);  
   
7. }

复制代码

BLINKER_WITHOUT_SSL目前仅可用于ESP8266，其他设备的RAM足以进行加密通信。最新的blinker lib已经支持关闭加密通信功能，如果您的esp8266项目可用ram不够，可通过这个功能关闭加密通信。

你好，我发现一旦取消SSL加密那么在blinker手机端就没办法看到设备在线了。

但是只要删除 BLINKER_WITHOUT_SSL 就可以显示在线。这有什么关系吗？

已经设备已经连上了wif，但是手机app端口一直显示离线。只有把这句话删除app端才显示在线。
