void(* btstack_uart_block_t::set_sleep)(btstack_uart_sleep_mode_t sleep_mode)

set UART sleep mode - allows to turn off UART and it's clocks to save energy Supported sleep modes:

• off: UART active, RTS low if receive_block was called and block not read yet
• RTS high, wake on CTS: RTS should be high. On CTS pulse, UART gets enabled again and RTS goes to low
• RTS low, wake on RX: data on RX will trigger UART enable, bytes might get lost

void(* btstack_uart_block_t::set_wakeup_handler)(void(*wakeup_handler)(void))

set wakeup handler - needed to notify hci transport of wakeup requests by Bluetooth controller Called upon CTS pulse or RX data.
