 ===== Supported Display types =====
 In general, all display types from nextion are supported, but it is recommended to use as minimum the 3,2 inch version in order to have sufficient space on the display.
-The type code is NX4024T032 [[https://nextion.itead.cc/resources/datasheets/nx4024t032|Link to the manufacturer]]. There is also a version with 4.2" available.

 Be aware: The updates of [[unipager|Unipager]] may not always be compatible with the UniPagerNextion software. If something is not working after an update, let us know and write a ticket to <code>support at hampager.de</code> or [[https://support.hampager.de/open.php|open a ticket]] directly.

+{{::icons:warning.png?direct |}}{{ :icons:warning.png?direct|}}Remember: In the default raspbian image, on Raspberry Pi 3B and Raspberry Pi 3B+, the internal Bluetooth is connected to the internal UART. So as it is quite likely you won't use the Bluetooth, disable it by adding a line
+<code>dtoverlay=pi3-disable-bt</code> to ''/boot/config.txt'' and disable the Bluetooth service with
+<code>sudo systemctl disable hciuart</code>
+Also free the UART from the kernel messages by removing
+<code>console=serial0,115200</code> from ''/boot/cmdline.txt'' and enable the UART by adding
+<code>enable_uart=1</code> to ''/boot/config.txt''
+Further information is just one google search away: [[https://www.raspberrypi.org/documentation/configuration/uart.md|one google search away]].
+Reboot your Pi after doing these actions.
