.2 Introduction of Network Upgrade Methods
In order to realize the network upgrade of the module, it is necessary to connect the line module
through wifi, and then to upgrade the data transmission according to the ip of the module.
4.2.1 Router Connection
Modules that need to be upgraded can be configured and connected to routers through serial port configuration
tools, or ap mode can be used.
4.2.2 Lookup Module IP
Because you need to input the ip, of the module when upgrading, you can go to the router to find the
corresponding ip, of
the module or use HLK-_Discover to search the corresponding ip. for the module in the local
area network.
