Ql_SOC_CreateEx is returning socket ID 242

I am using Qucetel MC60 module with Eclipse IDE and SDK version is V1.7. The thing is that, I am getting invalid socket 242 while calling Ql_SOC_CreateEx this function.

What are the possible causes why Ql_SOC_CreateEx is returning 242. This is causing Ql_Soc_ConnectEx error returning -4(invalid socket) due to which I am unable to connect to the server.

Dear Dev

Are you using the example in SDK_V1.7?Is the module mesh normal?

No, it’s custom code. I don’t understand what is module mesh

Dear dev

What do you mean by custom code?Is this API function encapsulated by yourself?

Is the module already connected to the core network?
