Thanks. It would be easier for me if I know what to look for. Is it wifi to serial? Before I go there, do these modules have their own wifi ID which I should connect to to talk my PIC OR they can connect to my wifi network? How is that accomplished? What features I should look for apart from serial capability? Using these modules, can I talk to my PIC from anywhere or only when I am connected to the same wifi network? Will my PIC also be able to send data over wifi to the outside world? I have many questions of these types which may be simple for someone who knows but challenging for me at this stage.
