Wifi Shield (Fi250) V1.1 is a economic internet solution with Arduino. The Wi-Fi module support IEEE 802.11b/g/n mode, maximum speed up to 65Mbit/s. Wifi Shield (Fi250) V1.1 combine on board antenna; it’s easy to build you project in a small box. The module reserve a UFL connector, you can use an extra antenna to improve the signal range. There is a key on the board, just push one time to change wifi shield as AP mode. The module have a computer interface software, you can control and upgrade the module via USB-UART convertor. The wifi shield contain a Micro SD card socket, it’s like a recorder when wifi shield working as TCP, UDP server.

The demo we use a Arduino Leonardo, we suggest you use a hardware serial port, software is not fast enough to communicate with the Wifi module.
Install Wifi Shield (Fi250) library, download demo code Wizfi250_Client.

-
If you need to reset the module as factory default. press the function three times as fast speed. The MODE and WIF LED flash, wait the module reset.
-
If the module reset as default, the baud rate change to 115200. kindly note that.
-
It's easy to enter AP mode. Press the Function button, wait the WIFI LED change as red. You can scan the wifi signal, WizFi250_AP_*******
-
Press the wifi shield Fi250 reset button exit AP mode.
The step for upgrade F/W show as below: Connect your wifi shield(Fi250) via UART directly,you can use a UartSBee or other UART tools
Before upgrade your F/W, you may set the module to Program mode (short BOOT jumper pin) wizfi250firmware
1st action
2nd action
3nd action
- When you update successful, move the jumper and restart the module.
