Accessing Blue Pill

DHCP or Static IP

The Blue Pill’s user interface is accessed via the device’s IP Address and any web browser. The IP address can be found on the display after it is plugged into a network connection with PoE or a network connection and a power supply (5V Micro USB).  By default the Blue Pill should get an IP address via DHCP, if that fails it should fallback to

Wi-Fi Access Point

If the Blue Pill is not displaying an IP address, the web interface is accessible by enabling the internal Wi-Fi access point. 

To enable the Wi-Fi access point, gently press and hold the config button on the side of the Blue Pill for about 3 seconds (Found next to the Ethernet jack. Use a flat screw driver, a paper clip or similar). When released, it will enable the internal Access Point and the LED will light up purple.

After accessing the Blue Pill it is best to navigate to the System Menu/System page to set a static IP address. Once saved, the new IP address will appear on the Blue Pill’s display, it may be necessary to reboot or power cycle the device afterwards.

Clicking on Configure next to the panel’s information will open the web interface directly. The Blue Pill does not need to be connected to the computer via USB.  image-1648117812215.png
