What's WiFi

Wi-Fi is actually the name of the organization is to develop an 802.11 wireless network,not on behalf of the wireless network.But then people gradually use wi-fi to call 802.11b protocol.Its the biggest advantage is the high transmission speed,and its effective distance is very long,but also compatible with existing 802.11 DSSS equipment.the wireless local area network (WLAN) mainstream use 802.11 often referred to as the WIFI network directly.

Fireduino WiFi chipset

On the Fireduino board integrated with WiFi module,using the AP6181 but actually is Broadcom BCM43362,it is a single-band 2.4GHz supports IEEE802.11b/g/n protocol,specific parameters of SDIO interface WiFi module please refer AP6181 and BCM43362 DataSheet.

Fireduino WiFi hardware connection

Main mcu of Fireduino board is connected to the WiFi module via SDIO interface communication, as follows:

The software structure of Fireduino WiFi

Fireduino SDK designed and developed to be compatible example of integrated library of Arduino WiFi Shield,which Fireduino upper application provides a rich interface,can be directly write web applications,without modifying the Arduino WiFi shields under the condition of sample can be run directly on the Fireduino.
