MC60 OPENCPU Multiple TCP connections as clients

i want to connect to two server at the same time with opencpu,
is there any function or should I use AT commands?
i could connect with AT commands to two server but i want use opencpu functions.
i read this document Quectel_GSM_TCPIP_Application_Note_V1.2 and connect to two server.

The sdk has the same functionality as the standard; you can refer to example_tcp´╝îUsing the api interface, follow the reference process to complete the connection. You can use example to successfully run through the process of setting up the server, and then modify it yourself
