I have the wizfi250 board and I want to connect it with an android via TCP client or server application.
- When I connect the wizfi250 through USB cable to a PC and then use putty, I can send AT commands to the module and RECEIVE an answer as "ok"
- When I have the module connected as AP , when I try to connect to it with the android, then the app seems to be connected with the module but when I send the command “AT” I do not get an answer! Will the module give me an answer when connected like that or not? What I have to do in order to speak to it and know that is listening?
- I try to send AT+FGPIO= 1, 5 in order to have 5Volts at general port #5 but it does not work. Is this the way to activate the general I/O pins?
