+ | {{::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. | ||
