Table A-1 Pin Assignment of Parani-BCD110V3
A.1.2. Bluetooth Connection Detect (UART_DCD) Signal
Status of Bluetooth connection will be delivered to Host PC via UART_DCD signal. When Bluetooth
connection is made, UART_DCD signal will be set to low.
A.1.3. Factory Reset (FACTORY_RESET) Signal
Parani-BCD110V3 provides a pairing signal input for instant configuration and automatic
connection to two Parani-BCD110V3s. In this example, we will name the two Parani-BCD110V3s
as BCD1 and BCD2 In pairing mode.
