3.6.1. BT_EN

BT_EN is used to control the Bluetooth function of FC800L. Bluetooth function will be enabled when

BT_EN is at high level.

Table 8: Pin Definition of BT_EN

3.6.2. UART Interface

FC800L supports an HCI UART as defined in

Bluetooth Core Specification Version 5.0

. The UART

supports hardware flow control, and it is used for data transmission with host. It supports up to 4.0 Mbps

baud rates.

The following table shows the pin definition of UART interface.
