3.1. Operation Modes

In  addition  to  the  serial  port  configurations,  the  Parani-ESD  requires  also  includes  some  settings  for
Bluetooth.  For  getting  the  most  out  of  Parani-ESD,  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-ESD has 4 operation modes as follows:

Table 3-1 The Parani-ESD Operation Modes

Mode

Description

Mode0

In this mode, there is no response when power on or software reset, and Parani-ESD is just
waiting for AT command input. Neither master nor slave is assigned to Parani-ESD in mode0.
User can change the configuration parameters of Parani-ESD in this mode.

Parani-ESD must be in Mode0, when it is directly controlled by AT commands.

The factory default is set to Mode0.

Mode1

Parani-ESD tries to connect the last connected Bluetooth device.
Parani-ESD in Mode1 is to be a master and tries to connect the last connected Bluetooth
device. Parani-ESD always stores the BD address of the Bluetooth device to which Parani-
ESD has connected last. When Parani-ESD is initially used or after hardware reset, there is no
BD address stored in Parani-ESD. In this case, Mode1 will not be able to work properly. The
mode change to Mode1 can be made after Parani-ESD succeeds to connect to one other
Bluetooth device. Once changed to Mode1, Parani-ESD will try to connect automatically the
last connected Bluetooth device whenever the unit is powered on or software reset.
Parani-ESD in Mode1 cannot be discovered or connected by other Bluetooth devices.

Mode2

Parani-ESD is waits for a connection from the last connected Bluetooth device.
Parani-ESD 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-ESD,
the mode change from other operation modes to Mode2 is not work properly. Once changed to
Mode2, Parani-ESD will wait for the connection from the last connected Bluetooth device
whenever the unit is powered on or software reset.
Parani-ESD in Mode2 cannot be discovered or connected to Bluetooth devices other than the
last connected device.

Mode3

Parani-ESD is waiting for the connection from any other Bluetooth devices. In Mode 3 the
Parani-ESD is discoverable and can be connected to by other Bluetooth devices.
