CX-WIFI-2NET Module Ethernet interface function
（
STA
）
The CX-WIFI-2NET module acts as a STA and the module works in bridge mode.
After the module is connected to the AP, the device on the Ethernet interface obtains
the IP address from the AP (as shown in Figure 192.168.1.101). At this time, the
entire network, the module is like a transparent device, and PC1 and PC2 can
communicate with each other without any constraint. However, if the CX-WIFI-2NET
module is to communicate with other devices, you need to statically set the LAN IP
address (as shown in Figure 192.168.1.10).
2.4.4 CX-WIFI-2NET Ethernet interface function (switch)
CX-WIFI-2NET module Ethernet interface function (switch)
The CX-WIFI-2NET module acts as an AP and the module works in switch mode.
The module is connected to the AP through the network cable 2, and is connected to
the PC1 through the network port 1, so that the PC1 obtains an IP (192.168.1.101)
from the AP. In this way, PC1 and PC2 can communicate directly under a LAN.
Multiple D2 modules can be added between PC1 and AP (both work in switch mode),
so that the modules can be extended by hand, so that the coverage of the AP
network can be extended.
Note: In this mode, the module DHCP should be turned off with
AT+DHCPDEN=off, otherwise the network will be abnormal. To access the module,
you need to manually change the LAN port address of D2 to the same network
segment (192.168 above). 1.102).
2.5 WI-FI parameter settings
2.5.1 Automatic frequency selection
When the module works in STA mode, the module adjusts itself to the same
channel as the AP according to the wireless channel of the AP and accesses it.
When the module works in AP mode, it can be set to automatic frequency
selection mode, so when the module starts, it will choose a better wireless channel
according to the surrounding environment.
2.5.2 Security Mechanism
The CX-WIFI-2NET module supports multiple wireless network encryption
methods to fully guarantee the secure transmission of data, including:
WEP
WPA-PSK/TKIP
