我正在使用 DEVIO NB-DEVKIT I（支持 NB-IOT）连接到 HiveMQ 的公共代理。
我正在使用 AIS（泰国电信服务）团队提供的代码。
我在代码中设置了以下设置：
String address = "broker.hivemq.com"; //Your IPaddress or mqtt server url
String serverPort = "1883"; //Your server port
String clientID = "mclient1"; //Your client id < 120 characters
String topic = "my/test/topic"; //Your topic < 128 characters
String payload = "HelloWorld!"; //Your payload < 500 characters
String username = ""; //username for mqtt server, username <= 100 characters
String password = ""; //password for mqtt server, password <= 100 characters
建立连接后的ESP32控制器反复重启，一直循环下去
错误信息如下所示。

我尝试使用硬件序列号使用AT命令订阅和发布并且它工作正常，这表明公司提供的code存在一些问题。
用于订阅和发布的 AT 串行命令。
AT+CMQNEW="broker.hivemq.com","1883",12000,100
AT+CMQCON=0,3,“myclient”,600,0,0
AT+CMQSUB=0, “my/test/topic”,1
AT+CMQPUB=0,"my/test/topic",1,0,0,24,"48656c6c6f202d204d515454"
如何修复 code 使其不会卡在重启循环中？
