Wireless Data Acquisition Card Application

As above figure, one WIFI232 configured as AP mode and all others configured as STA mode. All

WIFI232 which configured as STA and data server PC wireless connected to WIFI232 which

configured as AP to make up a wires network.

Data server PC open TCP/Server protocol and all WIFI232 modules open TCP/Client protocol. All data
acquisition cards‟ data and sampling information can be transmitted to data server PC for operation.
