3. Configuration
3.1. Operation Modes
In addition to the s erial port configuratio ns such as bit/second, data b it, parity, stop bit, flow co ntrol, Parani-ESD has some configurations 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 device, and slave is waiting to be connected from other Bluetooth devices. A Bluetooth connection is al ways made b y a pair of m aster and sl ave. A slave can be in t wo modes , Inquiry Scan or Page Scan m ode. Inquiry Sc an mode is waiting the pack et of inquir y from other Bluet ooth devices and Page Scan mode is waiting the packet of connection from other Bluetooth devices. Every Bluetooth device h as its uni que ad dress , calle d BD ( Bl uetooth Device) ad dress , whic h is com posed of 12 hexa-decimal numbers.
Parani-ESD has 4 oper ation modes as follows. Eac h mode can be identified with LED indicators as illustrated in next section.
Table 3-1 The Parani-ESD Operati on Mod es
Mode Description Mode0
Mode1
Mode2
Mode3
Parani-ESD 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-ESD is just waiting for AT command input. Neither master nor slave is assigned to Parani-ESD in mode0. User can change the configurations of Parani-ESD in this mode. The factory default is set to Mode0.
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 Parani­ESD has connected last time. When Parani-ESD is initially used or after hardware reset, there is no BD address stored in Parani-ESD. 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-ESD succeeds to connect to other Bluetooth device in Mode0. Once changed to Mode1, Parani-ESD will try to connect automatically the last connected Bluetooth device whenever power on or software reset. Parani-ESD in Mode1 cannot be discovered or connected by other Bluetooth devices.
Parani-ESD is waiting for the 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 allowed. Once changed to Mode2, Parani-ESD will wait for the connection from the last connected Bluetooth device whenever power on or software reset. Parani-ESD in Mode2 cannot be discovered or connected to Bluetooth devices other than the last connected device.
Parani-ESD is waiting for the connection from any other Bluetooth devices. Parani-ESD in Mode3 acts like in Mode2, but allows any connection from other Bluetooth device. Most of general Bluetooth device is set to Mode3. Parani-ESD in Mode3 can be discovered and connected from any other Bluetooth devices.

3.2.1. Data Bit
Parani-ESD supports only 8 data bit. In the case of 7 data bit, please contact the technical support.
3.2.2. Hardware Flow Control
Parani-ESD plugg ed into its host system transmits data from host to t he other side Bluetooth device. These data is saved temporarily in the internal buffer of Parani-ESD and sent repeatedly until the transmission is completed packet by packet. When the radio transmission condition is not good enough to send data prom ptly, it can cause the transm ission dela y. If the host sends more data when the buffer is full, buffer ove rflow will make Parani-E SD malfunction conseq uently. In order to prevent this buffer overflow, Parani-ESD works as follows.
In case of using har dware flow control, Parani-ESD mak es RTS be ‘disable’ to stop receiv ing further data from the host when the buffer becom es full. RTS will be ‘a ble’ to begin receiving data again f rom the host when the buffer has some room for more data.
In case of not using hard ware flow control, Paran i-ESD clears the buffer to s ecure the room for next data when the buffer becom es full. This means the l oss of data. As the transmiss ion data becomes large, the possibility of data loss goes higher.
For large data transmission, use of hardware flow control is highly recommended.

Figure 3-6 Device Setting Window
Parani-ESD supports two security options, Authentication and Encryption. If you check the Authentication op tion, you must also ent er the Pin Code valu e. If the authenticatio n is activated, the connection, onl y between the Master and Slave dev ice that sh are the sam e Pin Code, is establish ed. In case that Parani-ESD connects to other Bluetooth device that enables authentication, you must know the other device’s Pin Code. In general Bluetooth devic es, 1234 or 0000 is used as a defaul t
15
value. If you check Encryption option, the Parani-ESD encrypts packets and sends them. The Encryption options works well in case that only one between Master and Slave uses this option.
Parani-ESD has 4 resp onse messages, ‘OK’, ‘ERROR’, ‘CO NNECT’, and ‘DISCONNECT’. In som e cases, these responses can affect the host system unexpectedly. To prevent this, user can set the Command response to ON or OFF.
Click [Apply] button to reflect the given options to Parani-ESD actually. Connect(out) icon will show the following window to search and connect other Bluetooth devices.

A.1.4. RST Signal
RST signal will be used f or initializatio n of Parani-ESD. RST should be on 0V status f or at least 1 second for this.
A.1.5. Pairing Signal (only for Parani-ESD100/110)
Parani-ESD100/110 provides pairing sign al input for instant configurat ion without PC to make an automatic connecti on between two Parani-ESDs . For convenience sake, nam e two Parani-ESDs as ESD1 and ESD2 respectively.
Step 1. Turn off all the nearby Parani-ESD Step 2. Turn on ESD1 and ESD2 and hardware reset both of them by using RST signal. Step 3. Drop the pairing signal of ESD1 to low state and keep it for 2 seconds. Keep the power ON. Step 4. Drop the pairing signa l of ESD2 to low state and k eep it for 2 seconds. Rais e the pairing
signal of ESD2 to high state and keep it for 2 seconds. Now drop again the pairing signal of ESD2 to low state and keep it for 2 seconds
Step 5. Wait for ESD1 & ESD2 to be c onnected for a while. It takes about 10 seconds to m ake a
connection. If there are many Bluetooth devices nearby, it will take a little bit more.
Step 6. Now a pair of Parani-SD is configured to m ake automatic conn ection, whenever p ower off
and on.
Just use this pair of Parani-SD like virtual serial cable.
* Note: While pairing is progressing by the pairing signal, the Command Response will be inactivated automatically. Then, Parani-ESD will not send the response messages such as OK, Connect and Disconnect.

Description
Reference
In ‘Connect’ status, data from host is transmitted to the other side Bluetooth device, and any AT command is not accepted but this command, which is not echoed on the screen. When Parani-ESD encounters a character ‘+’ from host, it stops the data transmission and waits for next 2 characters. If the next 2 characters aren’t both ‘+’, it restart to transmit data including the first ‘+’ as well. If not, it converts the operation status to ‘Standby’. If the data from host includes ‘+++’, it will convert the operation status to ‘Standby’ unexpectedly. Notice that Parani-ESD holds data transmission when it encounters ‘+’, until receiving next character. ‘+’ is an escape sequence character by default, which is changeable by AT+SETESC.

Appendix C: S-Register
S-registers contain 46 parameters of Parani-ESD. These are stored in flash memory and sustained the values unless h ard ware re set is ex ecut ed. T he va lue o f S-regis ter c an be acc essed a nd c hanged with ATS command b y user. Some S-register s not shown below are set to maximize the perf ormance of Parani-ESD. Thus it is not recommended to change these S-registers. Change the value of S-register onl y in Standby status.
C.1. S1: Force to Reconnect (default 1)
S1=0, Parani-ESD in Mode1 does not try reconnection when disconnected. S1=1, Parani-ESD in Mode1 keeps trying reconnection when disconnected.
C.2. S2: Enable Hardware Flow Control (default 1)
S2=0, Parani-ESD’s hardware flow control is off. S2=1, Parani-ESD’s hardware flow control is on.
In case of SD Series, it can be changed only through dip switch.
C.3. S3: Stream UART Policy (default 0)
S3=0, the priority of UART streaming is throughput. S3=1, the priorit y is latenc y, which minim izes the delay of data transm ission. This is useful in cas e of
transmiting very small data quickly.
This value decides the way of handlin g str eam data from UART. When this value i s 1, in ord er tha t SD minimizes the late nc y, SD sends the received data im m ediately. When this value is 0, in order t hat SD maximizes throughput, SD stores received data for a short time and sends a large packet. If the packet length is less than100 b ytes, latency-or iented way is better. But if the packet length is more than 100 bytes, throughput-oriented way is recommended. Also if you want to use high baudrate, throughput-oriented way is more effective. Just for reference, the buffer length for receiving is 2 Kbytes.
C.4. S4: Enable Remote Name Query (default 1)
S4=0, Parani-ESD inquires only BD address. This speeds up the inquiry process. S4=1, Parani-ESD inquire BD address, device name and class of device.
This value dec ides whether SD finds friendly nam e of Bluetooth device or not. W hen this value is 1, SD finds not onl y BD addr es s but als o fr iendl y nam e. When this value is 0 , SD f inds onl y BD addr ess. Without finding friendly name, a searching is quick to respond. If you want to search the other Bluetooth devices quic kly, set this value to 0. In case of using pairing b utton, find ing friendl y name will be omitted automatically.
43
C.5. S6: Enable Low Power Mode (default 0)
S10=0, deactivate Low Power Mode. S10=1, activate Low Power Mode. This value decides whether SD works in Low Power Mode or not. When this value is 0, SD works only in active power mode. When SD works in Low Power mode, delay in transferring data may occur.
C.6. S10: Enable SD Response (default 1)
S10=0, Parani-ESD does not send SD responses to host system. S10=1, Parani-ESD send SD responses to host system.
This value decides whether SD sends response messages such as OK, ERROR, CONNECT, DISCONNECT or not. When this value is 0, SD sends no response messages. If the response messages cause troubles in host programs or devices that is connected to SD, change this value to 0.
C.7. S11: Enable Escape (default 1)
S11=0, Parani-ESD does not allow escape sequence character. The operation status of Connect cannot be
changed to Standby. As Parani-ESD skips the process detecting escape sequence character, the more efficient data transmission is expected.
S11=1, Parani-ESD allow escape sequence character. Whenever it is needed, the Connect status can be
changed to Standby.
C.8. S12: Clear Data Buffer When Disconnected (default 0)
S12=0, Parani-ESD does not clear the data buffer received from host system when disconnected. S12=1, Parani-ESD clears the data buffer when disconnected.
C.9. S14: Enable DTR Transfer (default 1)
S14=0, DTR/DSR signal is transferred to loop-back. S14=1, DTR signal is transferred to DSR of remote device.
C.10. S15: Enable Disconnect by DTR (default 0)
S15=0, DTR signal cannot release the connection. S15=1, The Bluetooth connection can be released when DTR signal is off.
This value decides whether Bluetooth connection is released when DTR signal drops or not. If this value is 1, you can use DTR signal in order to disconnect Bluetooth connection.
C.11. S22: Fast Connect (default 0)
S22=0, none S22=1, page scan S22=2, inquiry scan S22=3, page/inquiry scan
44
C.12. S24: Maximum Number of Inquiry Result (default 10)
The maximum number of inquiry list can be controlled. This value is up to 15,
C.13. S28: Escape Sequence Character (default 43)
The decimal number of the ASCII code of escape sequence character c an be controlled. The initial
value is 43, the ASCII code of ‘+’.
C.14. S31: Page Timeout (default 300)
This is the timeout in seconds to attempt connection with ATD command. After this timeout expires, the
SD will restart automatically. If this value is 0, SD will attempt to connect without restarting
C.15. S33: Inquiry Timeout (default 30)
This is the timeout in seconds to execute inquiry scan.
C.16. S37: Supervision Timeout (default 16000)
This is the timeout in 625µsec to presume disconnection, which is set to 16000 initially. 16000¯625µsec=10sec) The smaller the value be comes, the m ore quic kly Parani- ESD can det ect an a bnorm al disconnection . But when the co mmunication is suspende d for some environm ental reasons, it may be regar ded as disconnection.
C.17. S46: BD Address of Last Connected Device
This saves the BD address of the Bluetooth device connected most recently.

Appendix D: Trouble Shooting
D.1 No Data Transmission
D.1.1 COM Port Settings
Check whether the Baud rate of Parani-ESD is same as t hat of its host equipment. If you don’t know
the current Baud rate, initialize it to 9600 by resetting
Check whether the Data bit is s et to 8. Parani-ESD supports onl y 8 Data bit. If your host equipment uses 7 Data bit and even or odd parity, it can work as if it uses 8 Data bit an d No parity. This is valid only when both DCE devic es ar e Parani-E SD. In this c ase, set both P aran i-ESD s to 8 Data bit and No parity. If one of DCE devices is other Bluetoot h device suc h as Bluetooth U SB dongle, please c ontact Technical Support.
Check whether the Par ity and Stop bit of Parani-ESD are same as those of its host equipm ent. Par an i­ESD supports No parity, Even parity and Odd parity, 1 and 2 Stop bit.
Check whether the host equipment of Par a ni- E SD us e s Hard war e F l o w Con tr ol. Par an i- E SD is in iti al ly set to Use of Hardware Flo w Contro l. If your host equipm ent does not us e Hardw are Flo w Contr ol, set the Hardware Flow Control of Parani-ESD to No use.
Parani-ESD does not support RS-232 break signal.
D.2 Data Loss or Malfunctioning
D.2.1Hardware Flow Control
When transmitting lar ge data with No use of Hardware F low Control, Parani-ESD will c lear the data buffer unexpectedly. This possibility goes higher as the RF transmission environment is bad.
D.2.2 SD Response
The messages of AT response may affect the function of host system. Set ATS10=0 not to send AT response to host system and try again. Refer Appendix B. for details.

D.3 Transmission Delay
D.3.1 RF Processing Delay
It takes 30msec approxim ately for a Parani-ESD to com plete the data transmission to the other side Bluetooth device. This time delay cannot be reduced and would be bigger as the RF transmission environment is bad. Do not use Parani-ESD If your applications cannot allow this time delay.
D.3.2 RF Transmission Environment
If there are lots of Blue tooth device working in a sm all area and/or the RF communicat ion distance is too long and/or there are some obstacles affecting RF performance, Parani-ESD repeats the transmission packet by packet due to interferences and/or low RF performance. This leads the transmission time delay .
