A.1.3. Factory Reset Signal
Factory reset signal will be used for setting the Parani-ESD to factory defaults. Factory reset signal
should be on 0V status for at least 1 second for the reset to occur.
A.1.4. Pairing (BT_MODE) Signal (Single Connection Mode Only)
Parani-ESD provides a pairing signal input for instant configuration and automatic connection to two
Parani-ESDs. In this example, we will name the two Parani-ESDs as ESD1 and ESD2. In pairing
mode.
Step 1. Turn on ESD1 and ESD2 and do factory default both of them by using RST signal.
Step 2. Set the pairing signal of ESD1 to a low state and hold the signal for 2 seconds.
Step 3. Set the pairing signal of ESD2 to a low state and hold the signal for 2 seconds.
Set the pairing signal of ESD2 to high state and hold the signal for 2 seconds. Now Set the pairing
signal of ESD2 to low state and hold it for 2 seconds
Step 4. Wait for ESD1 & ESD2 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-ESD is configured to make automatic connection to each other.
You can now use this pair of Parani-
ESD‟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-ESD will not send the response messages such as OK,
Connect and Disconnect.

Using pairing button, users can make a pairing connection between a Parani-ESD unit and other
Bluetooth devices.
Step 1. Turn on ESD1 and do factory default by using RST signal.
Step 2. Set the pairing signal of ESD1 to a low state and hold the signal for 2 seconds.
Step 3. Users can discover and connect to ESD1 by using the software or user interface of other
Bluetooth device that they want to connect from.
Step 4. Wait for ESD1 & 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.
Step 5. Now ESD1 is waiting for a connection from the last connected Bluetooth device. The last
connected Bluetooth device can connect to ESD1.
