3. Configuration
3.1. Operation Modes
In addition to the serial port configurations, the Parani-BCDx10 requires also includes some settings
for Bluetooth. For getting the most out of Parani-BCDx10, user should understand the following
Bluetooth connection schemes.
A Bluetooth device can play a role as a master or slave. Master tries to connect itself to other
Bluetooth devices, and slave is waiting to be connected from other Bluetooth devices. A Bluetooth
connection is always made by a pair of master and slave devices. A slave can be in two modes,
Inquiry Scan or Page Scan mode. Inquiry Scan mode is waiting for a packet of inquiry from other
Bluetooth device and Page Scan mode is waiting for a packet of connection from other Bluetooth
device. Every Bluetooth device has its unique address, called BD (Bluetooth Device) address, which is
composed of 12 hexa-decimal numbers.
Parani-BCDx10 has 4 operation modes as follows:
Table 3-1 The Parani-BCDx10 Operation Modes
Mode Description
Mode0 In this mode, there is no response when power on or software reset, and Parani-BCDx10 is
just waiting for AT command input. Neither master nor slave is assigned to Parani-BCDx10 in
mode0. User can change the configuration parameters of Parani-BCDx10 in this mode.
Parani-BCDx10 must be in Mode0, when it is directly controlled by AT commands.
The factory default is set to Mode0.
Mode1 Parani-BCDx10 tries to connect the last connected Bluetooth device.
Parani-BCDx10 in Mode1 is to be a master and tries to connect the last connected Bluetooth
device. Parani-BCDx10 always stores the BD address of the Bluetooth device to which Parani-
BCDx10 has connected last. When Parani-BCDx10 is initially used or after hardware reset,
there is no BD address stored in Parani-BCDx10. In this case, Mode1 will not be able to work
properly. The mode change to Mode1 can be made after Parani-BCDx10 succeeds to connect
to one other Bluetooth device. Once changed to Mode1, Parani-BCDx10 will try to connect
automatically the last connected Bluetooth device whenever the unit is powered on or software
reset.
Parani-BCDx10 in Mode1 cannot be discovered or connected by other Bluetooth devices.
Mode2 Parani-BCDx10 is waits for a connection from the last connected Bluetooth device.
Parani-BCDx10 in Mode2 is to be a slave and waiting for the connection only from the last
connected Bluetooth device. Just like Mode1, if there is no BD address stored in Parani-
BCDx10, the mode change from other operation modes to Mode2 is not work properly. Once
changed to Mode2, Parani-BCDx10 will wait for the connection from the last connected
Bluetooth device whenever the unit is powered on or software reset.
Parani-BCDx10 in Mode2 cannot be discovered or connected to Bluetooth devices other than
the last connected device.
Mode3 Parani-BCDx10 is waiting for the connection from any other Bluetooth devices. In Mode 3 the
Parani-BCDx10 is discoverable and can be connected to by other Bluetooth devices.
