Using multiple FlashAirs to be connected to same wireless LAN

Latest update: June 2017

This tutorial demonstrates how to connect multiple FlashAirs to the same wireless LAN and to recognize and use each of them individually.

Configuration

Example of configuration

This tutorial uses the following devices.

  • FlashAir × 2 (all different versions and capacities are usable)
  • Wireless LAN router (Anything is acceptable if it becomes a wireless LAN parent machine)
  • PC with wireless LAN communication (anything is acceptable as long as wireless LAN communication is possible and a web browser can be used)

How to access FlashAir individually using APPNAME

First, change two FlashAirs to STA mode so that they can connect to the prepared wireless LAN router. To change FlashAir to STA mode, read "Method 1: Modify configuration file directly." in Using Station Mode

The value set in each FlashAir CONFIG file is, for example, as follows.

First FlashAir

APPMODE=5
APPNAME=flashair1
APPSSID=FOOSSID
APPNETWORKKEY=password0123

Second FlashAir

APPMODE=5
APPNAME=flashair2
APPSSID=FOOSSID
APPNETWORKKEY=password0123

APPSSID and APPNETWORKKEY will be the same since the SSID (e.g. FOOSSID) and the network key (e.g. password0123) of connected wireless LAN router are set. However, please be sure to set different APPNAME. When accessing from the PC connected to the same wireless LAN router in this state, specify the following in the web browser.

When accessing the first FlashAir

http://flashair1/

When accessing second FlashAir

http://flashair2/

When adding the third and more FlashAirs, please do not duplicate APPNAME as above (example: flashair 3, flashair 4 & … ).


How to recognaize and access to FlashAir individually by setting IP address.

Instead of setting APPNAME you can set IP_Address and access it individually. ( APPNAME can be set at the same time.)

The value set in each FlashAir CONFIG file is, for example, as follows.

First FlashAir

DHCP_Enabled=NO
IP_Address=192.168.43.11
Subnet_Mask=255.255.255.0
Default_Gateway=192.168.43.1

Second FlashAir

DHCP_Enabled=NO
IP_Address=192.168.43.12
Subnet_Mask=255.255.255.0
Default_Gateway=192.168.43.1

For Default_Gateway, set the IP address of connected wireless LAN router (e.g. 192.168.43.1). In accordance with that, please set IP_Address which is diffrent from Subnet_Mask (e.g. 255.255.255.0) and other devices connected to the wireless LAN route. When accessing from the PC connected to the same wireless LAN router in this state, specify the following in the web browser.

When accessing the first FlashAir

http://192.168.43.11/

When accessing second FlashAir

http://192.168.43.12/

When adding a third or more FlashAir, please do not duplicate IP_Address as above (example: 192.168.43.13, 192.168.43.14 & … ).
