3.6.1. BT_EN
BT_EN is used to control the BT function of FG50V module. BT function will be enabled when BT_EN is at high
level.

3.6.2. BT_WAKEUP_HOST* and HOST_WAKEUP_BT*
BT_WAKEUP_HOST and HOST_WAKEUP_BT are used to wake up the host and FG50V. If you use
Quectel RG50x series as the host, these two pins can be left unconnected because the wakeup function
can be achieved through BT UART.
The GPIO_1 connected to BT_WAKEUP_HOST must be interruptible.
