我正在使用 MC60ca 模块，
我想使用 Web 套接字，所以为了从我的服务器握手，我必须发送一个 HTTP GET 请求。请求的形式为：
“GET HTTP/1.1\r\nHost: echo.websocket.org:80\r\nUpgrade: websocket\r\nConnection: Upgrade\r\nSec-WebSocket-Version: 13\r\nSec-WebSocket-Key: Gsr/ P3vIWH+j2U5Rmt0Bkw==\r\n\0”</p>
我尝试使用HTTP EXAMPLEsdk1.6 发送它，但我收到 cme 错误 3810 和 3811 我也完成了requestheader = 1 AT+QHTTPCFG=“requestheader”,1\0
如何解决此请求错误？
