To configure a Nextion display, go to Connections → Nextion in the sidebar.

🔓 Nextion support is optional and requires a feature unlock. You can purchase the activation on grnbms.de. Once unlocked, the settings become available immediately.

In the first dropdown, select „Nextion“ as display type.

After selecting the type, the display model field will appear.
It is automatically detected after connection, but you may need to reload the page to see the result.

Select the serial port used to communicate with the display.
This is usually set to Display 1.

⚠️ Make sure the display is properly connected before saving.
If no model is detected, check wiring and baud rate under Connections → Serial Ports.

• Pre-flashed GRN displays: 115.2k baud
• New/unflashed displays: 9.6k baud (default factory setting)
