8. How to connect cloud platform

8.1 Wi-Fi Connection

In the first time of power on the devices, it would be set in ap mode and you can connect your pc/mobile phone to its wifi signal. It would be like Dusun_******, where the ****** are the last 6 bits of the devices’s MAC address. For example, the one in my test is Dusun_807F69

Wi Fi module 5

Then type in the ip 192.168.4.1 to log in the devices’s wifi, fill in the SSID and password of your router, then press Save button. Your devices would connect to your router automatically.
