bool "Three-wire UART (H5) protocol support"
depends on BT_HCIUART
help
The HCI Three-wire UART Transport Layer makes it possible to
user the Bluetooth HCI over a serial port interface. The HCI
Three-wire UART Transport Layer assumes that the UART
communication may have bit errors, overrun errors or burst
errors and thereby making CTS/RTS lines unnecessary.
Say Y here to compile support for Three-wire UART protocol.
