A.1.3. 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.1.4. Factory Reset(FACTORY_RESET) Signal
Factory reset signal will be used for setting the Parani-BCDx10 to factory defaults. Factory reset signal
should be on 0V status for at least 1 second for the reset to occur.
A.1.5. Pairing (BT_MODE) Signal (Single Connection Mode Only)
Parani-BCDx10 provides a pairing signal input for instant configuration and automatic connection to
two Parani-BCDx10s. In this example, we will name the two Parani-BCDx10s as BCD1 and BCD2 In
pairing mode.
Step 1. Turn on BCD1 and BCD2 and do factory default both of them by using RST signal.
Step 2. Set the pairing signal of BCD1 to a low state and hold the signal for 2 seconds.
Step 3. Set the pairing signal of BCD2 to a low state and hold the signal for 2 seconds.
Set the pairing signal of BCD2 to high state and hold the signal for 2 seconds. Now Set the pairing
signal of BCD2 to low state and hold it for 2 seconds
Step 4. Wait for BCD1 & BCD2 to connect to each other. It may take about 10 seconds to make a
connection. If there are many Bluetooth devices nearby, the connection time may increase.
Step 5. At this point your pair of Parani-BCDx10 is configured to make automatic connection to each
other.
You can now use this pair of Parani-BCDx10’s like virtual serial cable.
* Note : During the pairing process, by way of the pairing signal, the Command Response will be
deactivated. Thus, the Parani-BCDx10 will not send the response messages such as OK,
Connect and Disconnect.

Using pairing button, users can make a pairing connection between a Parani-BCDx10 unit and other
Bluetooth devices.
Step 1. Turn on BCD1 and do factory default by using RST signal.
Step 2. Set the pairing signal of BCD1 to a low state and hold the signal for 2 seconds.
Step 3. Users can discover and connect to BCD1 by using the software or user interface of other
Bluetooth device that they want to connect from.
Step 4. Wait for BCD1 & other Bluetooth device to connect to each other. It may take about 10
seconds to make a connection. If there are many Bluetooth devices nearby, the connection time
may increase.
