Quick Start
3.1
Restore factory settings
In order to ensure that all of configuration process is correct, bringing the module to restore
the factory settings firstly. Factory mode, the module can skip this step. Above 5V (500mA) to
power the module on the power, wait about 2.5 minutes for the system to start, after the start
completion, pulled ES / RST pin down and make it surpass Trst, release ES / RST pin, the system
will automatically restart. After rebooting, the system is already in Factory mode.
3.2
Configurate network parameter
Set the PC to static IP mode and then connect it with the module via Ethernet or wifi. The IP
address is set to 192.168.16.100/255.255.255.0, gateway 192.168.16.254. The (wifi default ssid and
the default password, see this document.) open the browser http://192.168.16.254, enter the web
