What can FlashAir do?

FlashAir is an iSDIO standard compliant device with wireless LAN functionality and a built-in micro computer.

Devices with an SD card slot such as cameras and PCs (i.e. SD host devices) will recognize the FlashAir as a SDHC memory card and be able to read/write data. Furthermore, SD host devices that support iSDIO commands can control the FlashAir's wireless LAN directly.

Since the FlashAir has a built-in web server, Wi-Fi devices can connect to the FlashAir and access its contents using HTTP (HyperText Transfer Protocol) on any modern browser.

FlashAir

  • Wireless LAN - Control Wireless LAN functions, such as enabling AP/STA mode, using both simultaneously (bridge mode), and scanning SSIDs.
  • HTTP - HTTP communication via Wireless LAN
  • Web server - By issuing HTTP GET requests to files on the FlashAir, you can download them. The FlashAir API includes CGI commands to get list of files and to customize your configuration.
  • Script - You can execute Lua scripts on FlashAir.
  • GPIO - You can GPIO control of the SD terminal.
  • SD - You can read from and write files on the internal flash memory.
  • Other - You can read from and write SRAM.

FlashAir Application Development

Application development depends on the type of device you're using.

FlashAir Versions

There are four versions of FlashAir cards: First Generation (W-01) , Second Generation (W-02) , Third Generation (W-03) , and Fourth Generation (W-04) . In the second generation, the SD memory card corresponds to Class 10, the fourth generation corresponds to UHS speed class 3, and the speed is increased, and the transfer rate by the fourth generation radio is about 2.9 times the third generation.

The first generation firmware version 1.00 series, second generation the 2.00 series, third generation the 3.00 series, fourth generation follows the trend and is called the 4.00-series. In 2.00 series, the API specification has been greatly expanded. Application developers should pay attention to differences in behavior due to firmware.

Read / write maximum speed

Read: 90MB/s
Write: 70MB/s
∗We calculate 1 MB/sec as 1,000,000 bytes/second. The maximum transfer speed is the best value obtained under specific conditions in the Toshiba test environment, and it does not guarantee the speed in the equipment used. Read / write speed may vary depending on the condition of the equipment, etc. to be used. The transfer rate of a conventional SD interface will be reduced compared to the UHS-I interface.

Wireless transfer rate

About 31.4 Mbps About 10.8 Mbps
∗Measured values are measured independently by the manufacturer, and do not guarantee the actual transmission speed. The actual wireless transmission speed varies depending on the equipment and environment used.

UHS

It is an interface that can be used with SDHC / SDXC memory card, and high speed performance can be obtained by using with compatible equipment.

UHS-I
UHS Speed Class3

Speed class

It is a standard that specifies the data transfer rate with the SD host device. In Class 10, the data transfer speed at read / write is at least 10 MB/sec.

Class 10 Class 10

Supported firmware
