4.3.4. Network receive cache
All links have a total of 15K (15*1024Bit) network cache to alleviate the impact of the network speed being greater
than the serial port speed during continuous transmission.
4.4. Support DHCP and domain name resolution
4.4.1. DHCP
AP mode supports dynamic allocation of I P of connected devices;
STA mode device can automatically obtain IP through the router, and automatically configure the subnet mask and
DNS server, support modifying the subnet mask and DNS server, modification error may cause the device to work
abnormally. It is recommended that the subnet mask be modified with the DNS server when dynamically acquiring
IP (when statically switching to dynamic, the device automatically synchronizes the subnet mask with the DNS
server).
4.4.2. DNS
When the other modes are switched to STA mode, the device automatically follows the router to configure the DNS
server, and the user can enter the configuration of the custom DNS server again to meet the needs of custom
domain name resolution.
