That is not related to the MacArthur HAT.
The Raspberry shares UART0 and Bluetooth interfaces. If you enable UART0 for MAIANA, dAISy, pypilot... the Bluetooth is disabled and the opposite.
I do not recommend editing the config.txt file, let openplotter-serial app do the work when enabling/disabling UART0 or your system could become unstable.
