The CPU module comprises an MT7621A chip, a DDR3L chip and a Flash chip, wherein the DDR3L chip is connected with the MT7621A chip through a DDR protocol interface, the Flash chip is connected with the MT7621A chip through a parallel port, and the WiFi6 wireless module is connected with the MT7621A chip through a PCIE interface.
The MT7621A chip of the device drives the WiFi6 wireless module to work through the PCIE interface, and sends out wireless network signals. A plurality of devices of the invention are respectively used as a master mesh device and a slave mesh device to form a mesh network (wireless mesh network) under the drive of a WiFi6 wireless module. The mesh equipment is powered on, the system drives the WiFi6 wireless module to transmit a wireless network, and after the MT7621A chip is driven, the master mesh equipment and the slave mesh equipment carry out mesh networking through a wireless mesh protocol. After networking is successful, the slave mesh device reports state information to the master mesh device at regular time, and the master mesh device controls the slave mesh device to work according to data reported by the slave mesh device at the same time, wherein the networking mode comprises three modes of fig. 2-4.

The networking mode in fig. 3 is similar to the networking mode in fig. 2, and the difference is that R1 is in a bridge mode, and this networking mode can allow a device accessed to a mesh network to obtain a public network ip, which provides convenience for a user needing remote control.

In the first stage, when mesh networking is carried out on the master mesh equipment and the slave mesh equipment, key exchange and verification are carried out, and if the verification is successful, a wireless link is established. In the second stage, the main mesh sends a topology discovery broadcast packet to discover all access devices in the mesh network and establish a topology database. The third stage configures all slave mesh devices of the sub-mesh network.
