FSC-BT826HC

EXT_ANT RF signal output

By default, this PIN is floating

. This PIN can connect to an

external antenna to improve the Bluetooth signal

coverage.

If you need to use an external antenna, by modifying the

module on the 0R resistance to block out the on-board

antenna; Or contact Feasycom for modification.

5. Interface Characteristics

5.1 UART Interface

Four signals are used to implement the UART function. When FSC-BT826HC is connected to

another digital device, UART_RX and UART_TX transfer data between the two devices. The

remaining two signals, UART_CTS and UART_RTS, can be used to implement RS232

hardware flow control where both are active low indicators.

The interface consists of four-line connection as described in below:

Signal name Driving source Description

UART-TX FSC-BT826HC module Data from FSC-BT826HC module

UART-RX Host Data from Host

UART-RTS FSC-BT826HC module Request to send output of FSC-BT826HC module

UART-CTS Host Clear to send input of FSC-BT826HC module
