3. Configuration
3.1 Using Parani10 Manager
With Parani10, Bluetooth wireless connections can be made to any Bluetooth device
supporting SPP (Serial Port Profile).
Especially when using the Parani10 as a cable
replacement, take advantage of the Parani10 automatic connection feature. Once a pair of
Parani10’s is set for this feature, they automatically connect whenever powered up. A pair of
Parani10 units, within their radio range, may be used as a virtual RS-232 cable.
To allow wireless connections between two Bluetooth devices, one device should be in
Discoverable (INQUIRY SCAN) and Connectable (PAGE SCAN). Most Bluetooth devices are
set to Discoverable and Connectable by the manufacture. However, to allow Parani10 to
respond to the INQUIRY and PAGE operations of other Bluetooth devices, INQUIRY SCAN and
PAGE SCAN modes will need to be activated.
Before making the first Bluetooth connection with Parani10 units, be prepared with a pair of
Parani10 units and also install the Parani10_Manager program on the CD enclosed in the
Parani10 product package.
*Configuration By Parani10_Manager

Parani10 default configuration is 9600 bps Baud, 8 Data bit, No Parity, 1
Stop bit and H/W flow control.
5. Enter ‘AT’ command at the prompt. A Parani10 ‘OK’ reply indicates proper
operation.
3.2.2 Making the first Parani10/Bluetooth connection
As stated before, Bluetooth wireless connections can be made with any
other Bluetooth device supporting Bluetooth SPP (Serial Port Profile).
For Bluetooth wireless connections to a Parani10, first make another
Parani10 ‘Discoverable’ and ‘Connectable’.
In this case, refer to
section 3.2.3 before following the instructions below.
1. First check the status of the Parani10 by entering ‘AT+BTINFO?’. The
Parani10 response is comprised of BD_ADDR, Device Name, Operating
Mode, Operating Status, Authentication and Encryption flags. To make a
connection to other Bluetooth devices, the operating status of the first
Parani10 should be ‘STANDBY’. A ‘PENDING’ operating status of the first
Parani10 indicates the unit is busy with another operation. In this case,
cancel the ongoing operation by entering the ‘AT+BTCANCEL’ command.

3.2.4 Releasing the existing Bluetooth connection
Once connected successfully, the Parani10 becomes transparent to any serial
applications on hosts. Data may be transferred within the radio range of the
Parani10. According to Parani10 terminology, this operating status is called
‘ONLINE STATUS’. In ONLINE STATUS, all AT commands are treated as
characters and are ignored by the command interpreter of the Parani10.
Therefore to escape from ONLINE STATUS enters escape string ‘+++’.
22
1. Transition from ONLINE STATUS to STANDBY STATUS by entering ‘+++’
string to the Parani10. Check the current Parani10 status by entering the
‘AT+BTINFO?’ command. The Parani10 status should display CONNECT
