Sena Technologies Inc. PARANISD1100 Manuel D’Utilisation

In addition to the serial port configurations the Parani-SD1100 also requires some settings for 
Bluetooth. For getting the most out of Parani-SD1100, 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-SD1100 has 4 operation modes as follows. Each mode can be identified with LED indicators as 
illustrated in next section. 
 
 

 

In this mode, there is no response when power on or software reset, and Parani-SD1100 is 
just waiting for AT command input. Neither master nor slave is assigned to Parani-SD1100 in 
mode0. User can change the configuration parameters of Parani-SD1100 in this mode. 
 
Parani-SD1100 must be in Mode0, when it is directly controlled by AT commands. 
 
The factory default is set to Mode0. 

Parani-SD1100 tries to connect the last connected Bluetooth device. 
Parani-SD1100 in Mode1 is to be a master and tries to connect the last connected Bluetooth 
device. Parani-SD1100 always stores the BD address of the Bluetooth device to which Parani-
SD1100 has connected last. When Parani-SD1100 is initially used or after hardware reset, 
there is no BD address stored in Parani-SD1100. In this case, Mode1 will not be able to work 
properly. The mode change to Mode1 can be made after Parani-SD1100 succeeds to connect 
to one other Bluetooth device. Once changed to Mode1, Parani-SD1100 will try to connect 
automatically the last connected Bluetooth device whenever the unit is powered on or software 
reset. 
Parani-SD1100 in Mode1 cannot be discovered or connected by other Bluetooth devices. 

Parani-SD1100 is waits for a connection from the last connected Bluetooth device. 
Parani-SD1100 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-
SD1100, the mode change from other operation modes to Mode2 is not work properly. Once 
changed to Mode2, Parani-SD1100 will wait for the connection from the last connected 
Bluetooth device whenever the unit is powered on or software reset. 
Parani-SD1100 in Mode2 cannot be discovered or connected to Bluetooth devices other than 
the last connected device. 

Parani-SD1100 is waiting for the connection from any other Bluetooth devices. In Mode 3 the 
Parani-SD1100 is discoverable and can be connected to by other Bluetooth devices.
