Question

我试图将BG96连接到亚马逊服务器，但是一旦通信打开（AT + QMTOPEN = ... return + QMTOPEN：1.0），如果我尝试与对象连接（AT + QMTCONN = 1， “ thingname”）回答“确定”，然后回复+ QMTSTAT：1,1（连接断开）。

与其他设备（树莓派或arduino）的连接没有问题，因此对于该主题，我将排除服务器端配置问题： error when publish data to aws IoT using BG96 and MQTT protocol

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
OK
AT+QSSLCFG="ignorelocaltime",1,0
OK
AT+QICSGP=1,1,"wap.tim.it"
OK
AT+QICSGP=1
+QICSGP: 1,"wap.tim.it","","",1
OK
AT+QIACT?
+QIACT: 1,1,1,"***.**.**.***"
OK
AT+QMTOPEN=1,"**************.iot.us-east-2.amazonaws.com",8443
OK
+QMTOPEN: 1,0
AT+QMTCONN=1,"thingName"
OK
+QMTSTAT: 1,1

Answer 1

我发现了问题，这是将MQT和TLS BG96模块连接到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

使用BG96和MQTT协议将数据发布到AWS IoT时连接断开
