Parani-SD100 User Manual – 2. Configurations 7 Operation Modes In addition to the serial port configurations such as bit/second, data bit, parity, stop bit, flow control, Parani-SD has some configurations for Bluetooth. For getting the most out of Parani-SD100, 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 device, and slave is waiting to be connected from other Bluetooth devices. A Bluetooth connection is always made by a pair of master and slave. A slave can be in two modes, Inquiry Scan or Page Scan mode. Inquiry Scan mode is waiting the packet of inquiry from other Bluetooth devices and Page Scan mode is waiting the packet of connection from other Bluetooth devices. Every Bluetooth device has its unique address, called BD (Bluetooth Device) address, which is composed of 12 hexa-decimal numbers. Parani-SD100 has 4 operation modes as follows. Each mode can be identified with LED indicators as illustrated in next section. Ì Mode0 Parani-SD100 must be in Mode0, when it is directly controlled by AT commands. In this mode, there is no response when power on or software reset, and Parani-SD100 is just waiting for AT command input. Neither master nor slave is assigned to Parani-SD100 in mode0. User can change the configurations of Parani-SD100 in this mode. The factory default is set to Mode0. Ì Mode1 Parani-SD100 tries to connect the last connected Bluetooth device. Parani-SD100 in Mode1 is to be a master and tries to connect the last connected Bluetooth device. Parani-SD100 always stores the BD address of the Bluetooth device to which Parani-SD100 has connected last time. When Parani-SD100 is initially used or after hardware reset, there is no BD address stored in Parani-SD100. In this case, Mode1 does not make any sense and mode change from other operation modes to Mode1 is not allowed. The mode change to Mode1 can be made after Parani-SD100 succeeds to connect to other Bluetooth device in Mode0. Once changed to Mode1, Parani-SD100 will try to connect automatically the last connected Bluetooth device whenever power on or software reset. Parani-SD100 in Mode1 cannot be discovered or connected by other Bluetooth devices. Ì Mode2 Parani-SD100 is waiting for the connection from the last connected Bluetooth device. Parani-SD100 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-SD100, the mode change from other operation modes to Mode2 is not allowed. Once changed to Mode2, Parani-SD100 will wait for the connection from the last connected Bluetooth device whenever power on or software reset. Parani-SD100 in Mode2 cannot be discovered or connected to Bluetooth devices other than the last connected device. Ì Mode3 Parani-SD100 is waiting for the connection from any other Bluetooth devices. Parani-SD100 in Mode3 acts like in Mode2, but allows any connection from other Bluetooth device. Most of general Bluetooth device is set to Mode3. Parani-SD100 in Mode3 can be discovered and connected from any other Bluetooth devices.

Serial Port Settings Values Baud rate 1200, 2400, 4800, 9600 , 19200, 38400, 57600, 115200, 230400 Data bit 8 Parity No parity , Even parity, Odd parity Stop bit 1 , 2 Hardware Flow Control Use , No use The values in box are the factory defaults. Ì Data Bit Parani-SD100 supports only 8 data bit. In the case of 7 data bit, please contact the technical support. Ì Hardware Flow Control Parani-SD100 plugged into its host system transmits data from host to the other side Bluetooth device. These data is saved temporarily in the internal buffer of Parani-SD100 and sent repeatedly until the transmission is completed packet by packet. When the radio transmission condition is not good enough to send data promptly, it can cause the transmission delay. If the host sends more data when the buffer is full, buffer overflow will make Parani-SD100 malfunction consequently. In order to prevent this buffer overflow, Parani-SD100 works as follows. In case of using hardware flow control, Parani-SD100 makes RTS be ‘disable’ to stop receiving further data from the host when the buffer becomes full. RTS will be ‘able’ to begin receiving data again from the host when the buffer has some room for more data. In case of not using hardware flow control, Parani-SD100 clears the buffer to secure the room for next data when the buffer becomes full. This means the loss of data. As the transmission data becomes large, the possibility of data loss goes higher. For large data transmission, use of hardware flow control is highly recommended. Reset to Factory Defaults To turn back all the configurations to its factory settings, press the reset button depicted in Fig. 1-3. Press the reset button with a narrow pointed tool like paper clip longer than 1 second. Reset works only when power is on.
