问题描述
我是物联网和AWS的新手，我在通过gsm模块与AWS MQTT交流时遇到了问题
首先，我通过一个示例，使用一个WIFI客户端，通过设置私有，根和证书，使用WIFI库与AWS MQTT进行通信
wiFiClient.setCACert(rootCA);// GSM security API or GSM x509 certificate
wiFiClient.setCertificate(certificate_pem_crt);
wiFiClient.setPrivateKey(private_pem_key);
但是现在我想使用GSM模块而不是wifi进行通信 那么有人可以帮助我如何使用GSM客户端而不是WIFI客户端设置这些x509代码吗？
换句话说，通过使用GSM模块来替代上述3行代码
如果有任何示例或文档或直接答案
在我的代码的一部分之后：
