WiFi module (HLK RM-04) inetrface with microcontroller say mega16

Its a serial-eth-wifi module, The serial communication between the module and uC and RM-04 is good, but the question is how do i transmit data to wifi module... do i need embedded web server in my uC ?

actually my design is uC (serial) <---> WIfi module <--> computer (via ethernet) this is for now. i have not included wifi in it initially.
i have searched much about the web server and studying for my networking concepts, but any sharing or guidance will be helpful.

the actual problem is HLK RM - 04 is not much discussed on forums. here is its data sheet .

    Thanks for the reply.

    Yes the module is perfect for the application.
    the problem is how do i send any data via this module ?
    do i realle need a embedded web server ? so i can allocate a ip to uC and then communicate with PC with some web interface ?
    or can directly communicate is some other mode ?

    According to the information I think you can setup your requirement using AT commands. No need to use any thing else.
    uC (serial) <---> WIfi module <--> computer (via ethernet) can work for you.
    Try to explore it's datasheet you will find commands for the same.
