UART HCI Bluetooth Module
=========================

There is a Bluetooth 4.2 dual-mode controller inside the ESP32 chip, which can use UART(H4) as HCI IO.

## Pinmap

| HOST  | RX | TX | CTS | RTS |
| :---- | -: | -: | --: | --: |
| ESP32 | TX | RX | RTS | CTS |
| Pin   |  5 | 18 |  19 |  23 |

* HCI UART protocol: `H4`
* HCI UART baudrate: `921600 bps`
