A.1.3. Factory Reset Signal
Factory reset signal will be used for setting the IW06 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)
IW06 provides a pairing signal input for instant configuration and automatic connection to two IW06s.
In this example, we will name the two IW06s 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 IW06 is configured to make automatic connection to each other.
You can now use this pair of IW06’s like virtual serial cable.
* Note : During the pairing process, by way of the pairing signal, the Command Response will be
deactivated. Thus, the IW06 will not send the response messages such as OK, Connect and
Disconnect.

Using pairing button, users can make a pairing connection between a IW06 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.
