Wizfi 250 comms through TCP client

Question

Hello, 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” BUT 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? Thank you, Best Regards, Andreas Achilleos

Hi soellicha. Q: 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? [quote]A: When you send the command “AT” at the APP, you can’t get an answer. The App(TCP Clinet) just sent “AT” as a DATA, not an AT Command for module control. If you want to control the module at the APP(TCP Client), you have to use the command “AT+MAIRCMD”. Please refer to the following link.

The “AT” was sent by APP(TCP Client). 450×800 63.9 KB A WizFi250(APmode TCP Server) can receive “AT” as a data.

[quote]A: There is the way to activate the general I/O pins. AT+FGPIO=1,5,1 << it means that a GPIO 5 set to HIGH AT+FGPIO=1,5,0 << it means that a GPIO 5 set to LOW First option: to set GPIO value. Second option: GPIO number Third option: 1=HIGH, 0=LOW Please refer to the following connections. I recommend using 3.3V instead of 5V [/quote] [quote] [/quote] Thanks.
