4.1.2. Cache function
The connection clears the serial port data, with a 15K (15*1024Bit) serial port cache. When the network is not
connected, the data sent by the user will be recorded. After the network connection is successful, the data will be
sent out normally.
4.2. Job role
4.2.1. AP mode
（
Access Point
）
Access Point is referred to as AP mode, which is similar to a router, allowing wireless devices to connect and
establish TCP/IP-based server, client, and UDP communications. In this mode, 3 stations are supported, and a
maximum of 4 TCP sockets are supported.
4.2.2. STA mode
（
Station
）
Station mode is abbreviated as STA. In this role, the device does not provide connection, but can only connect to an
Access Point or a router. This device supports TCP server, TCP client, UDP in the Station role, and supports up to 4
sockets. The device works from other working roles. When switching to STA mode, the device will automatically
enable DHCP to obtain IP, and automatically configure the subnet mask and DNS domain name server.
4.3. Transfer mode
Transmission mode refers to the number of sockets supported by the device under the TCP/IP protocol. When only
