我尝试将 BG96 连接到亚马逊服务器，但是，一旦通信打开（AT + QMTOPEN = ... return + QMTOPEN: 1.0），如果我尝试连接我的对象（AT + QMTCONN = 1，“thingname” ) 回复 ok 和 + QMTSTAT: 1,1 （连接断开）。

使用其他设备（覆盆子 pi 或 arduino）连接没有问题，所以我将排除服务器端配置问题，因为这个主题： 使用 BG96 和 MQTT 协议将数据发布到 aws IoT 时出错

这些是 AT - 命令：

AT+QSSLCFG="ciphersuite",1,0x0035
OK
AT+QSSLCFG="cacert",1,"ufs:cacert.pem"
OK
AT+QSSLCFG="clientcert",1,"ufs:clientcert.pem"
OK
AT+QSSLCFG="clientkey",1,"ufs:clientkey.pem"
OK
AT+QSSLCFG="sslversion",1,4
OK
AT+QSSLCFG="seclevel",1,2
OK
AT+QSSLCFG="negotiatetime",1,300

AT+QSSLCFG="ignorelocaltime",1,0

AT+QICSGP=1,1,"wap.tim.it"

AT+QICSGP=1

AT+QMTCONN=1,"thingName"

我发现了问题，这是将 BG96 模块的 MQTT 和 TLS 连接到 Amazon AWS 的正确代码：

AT+QICSGP=1,1,"Your APN"
OK
AT+QICSGP=1
+QICSGP: 1,"wap.tim.it","","",1
OK
AT+QIACT=1
OK
AT+QIACT?
+QIACT: 1,1,1,"***.***.***.***"
OK
AT+QMTCFG="SSL", 1, 1, 1
OK
AT+QSSLCFG="cacert",1,"ufs:cacert.pem"
OK
AT+QSSLCFG="clientcert",1,"ufs:clientcert.pem"
OK
AT+QSSLCFG="clientkey",1,"ufs:clientkey.pem"
OK
AT+QSSLCFG="sslversion",1,4
OK
AT+QSSLCFG="seclevel",1,2
OK
AT+QSSLCFG="ciphersuite",1,0xFFFF
OK
AT+QSSLCFG="ignorelocaltime",1
+QSSLCFG: "ignorelocaltime",1,1
AT+QMTOPEN=1,"*********.iot.us-east-2.amazonaws.com",8883
OK
+QMTOPEN: 1,0
AT+QMTCONN=1,"YOUR_THING_NAME"
OK
+QMTCONN: 1,0,0
AT+QMTSUB=1,1,"YOUR_TOPIC",1
OK    
+QMTSUB: 1,1,0,1
AT+QMTPUBEX=1,1,1,0,"YOUR_TOPIC","TEXT_TO_PUBLISH"
OK
+QMTPUB: 1,1,0
