international a standard for short range wireless communications. Parani-ESD can communicate with
other Bluetooth devices that support the Serial Port Profile.

Parani-ESD lineup has several models with different communication ranges from 30m (Parani­ESD200/210) up to 100m (Parani-ESD100/110) for use with various applications. The Parani-ESD
delivers better quality of communication than a standard RS232 cables.

Parani-ESD has a compact design and can be placed conveniently into devices or equipment. Its
detachable antenna optimizes the quality and distance for wireless communications.

Parani-ESD supports FHSS (Frequency Hopping Spread Spectrum), which is a technique, native to
Bluetooth that allows the Parani-ESD minimize radio interference while decreasing the likelihood of
over-air hijacking. Parani-ESD also supports authentication and Bluetooth data encryption.

Parani-ESD can be configured and controlled by typical AT commands. Users can easily configure
Parani-ESD by using a terminal program such as HyperTerminal and can use Bluetooth wireless
communication without modifying user’s existing serial communication program. In addition to the
basic AT commands, Parani-ESD provides some expanded AT commands for various functions. User
friendly ParaniWizard and ParaniWIN are also provided for easy setup on MicrosoftWindows.

Note *:

Bluetooth v1.2 supports improved AFH function. AFH function is to mitigate the
interference between WiFi and Bluetooth radios by automatically avoiding the
active WiFi channel from Bluetooth link. However, AFH does not provide a
complete solution making WiFi and Bluetooth work together in harmony. It is
highly recommended for users to test their wireless system enough before
deployment since the overall system performance is affected by various
environmental factors such as distance between them.

3. Configuration

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 responsewhen 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 ATcommands.
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 deviceto which Parani­ESD 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 automaticallythe
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 operationmodes 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.

The values in box are the factory default settings.

3.3 Data Bit

Parani-ESD supports only 8 data bit. In the case of 7 data bit and even/odd parity, use Parani-ESD 8
data bit and none parity. At this time, master and slave are Parani-SD, Parani-ESD or Parani-MSP
series. But 7 data bit and none parity is not support.

3.4 Hardware Flow Control

Parani-ESD plugged into its host system transmits data from host to the other side Bluetooth device.
This 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 promptly, it can cause a transmission delay. If the host sends more data when the
buffer is full, buffer overflow will make Parani-ESD malfunction consequently. In order to prevent this
buffer overflow, Parani-ESD works as follows.

When using hardware flow control, Parani-ESD disables RTS so that it stops receiving any further
data from the host when the buffer becomes full. RTS will be re-enabled again to begin receiving data
from the host when the buffer has created more room for more data.

When hardware flow control is not being used, the Parani-ESD clears the buffer to secure room for the
next data when the buffer becomes full. This can mean a loss of data may occur. As the transmission
data becomes large, the possibility of data loss becomes greater.

For large data transmissions, the use of hardware flow control is highly recommended.

be configured as well. Security option also can be configured in this window.

17

Figure 3-5 Device Setting Window

Parani-ESD supports two security options, Authentication and Encryption. If you check the
Authentication option, you must also enter the Pin Code value. If the authentication is activated, the
connection, only between the Master and Slave device that share the same Pin Code, is established.
Parani-ESD supports two security options, Authentication and Encryption. If you enable the
Authentication option, you must also enter a Pin Code value. If the authentication is enabled, the
connection, between the Master and Slave device must share the same Pin Code. In case that Parani­ESD connects to another Bluetooth device, that requires authentication, you must know the other
device’s Pin Code. In general, most Bluetooth devices have a pincode of 1234 or 0000. If you check
Encryption option, the Parani-ESD will encrypt packets and sent to the device. The Encryption options
works well in case that only one of the devices between Master and Slave use the Encryption option.

Parani-ESD has 4 response messages, ‘OK’, ‘ERROR’, ‘CONNECT’, and ‘DISCONNECT’. In some
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 apply any changes made to the Parani-ESD.
Connection(out) icon will show the following window to search and connect other Bluetooth devices.

18

Figure 3-6 Connection(out) Window

Click [Search] button to search nearby Bluetooth devices. Once several Bluetooth devices has been
found, select one of the devices and click the [Connect] button. The selected Bluetooth device must be
discoverable and connectable. Click [Disconnect] button to cancel the connection.

After the connection has been established, you will be able to test signal strength by pushing the
START button.

19

Figure 3-7 Signal Strength Test

The signal strength test shows LInkQuality and RSSI values. The closer LinkQuality is to 255 and
RSSI is to 0, this means the Parani-ESD has a good connection to the connected Bluetooth device. In
general, the wireless connectivity is at its best within 10 meters. You can push the STOP button at
anytime in order to terminate the signal strength test. The signal strength test will continue until the
STOP button is pushed. If you close the ParaniWIN Window without pushing the STOP button, you
must restart Parani-ESD to terminate the test.

Connection(in) icon will show the following window, which enables the Parani-ESD to wait for a
connection from another Bluetooth device. If the waiting time is set to 0, Parani-ESD will continually
wait for connection until [Cancel] button is clicked.

20

Figure 3-8 Connection(in) Window

If the Connection Wizard icon is clicked, an easy to use pairing menu will appear:

Figure 3-9 Connection Wizard Window

In this example we will refer to the two Parani-ESDs as ESD1 and ESD2 respectively. To use this
menu, please do the following:

Step 1. Connect ESD1 and then push the START button.
Step 2. Disconnect ESD1, connect ESD2 and then push the Next button after setting up Slave

configuration.

Step 3. Disconnect ESD2, once again connect the ESD1 and then push the Finish button. The pairing

configuration should be completed. Make sure that each Parani-ESD’s connect LED is on. At this
point, when both Parani-ESD’s are restarted the connection will be established automatically.

3.7 ParaniWizard

ParaniWizard is a Wizard program that will allow you to configure a pair of Parani-ESD’s for an
automatic connection. To make connection with Bluetooth devices other than Parani-ESD, use
ParaniWIN or AT commands on a terminal program.
In this example, we will refer to the two Parani-ESD’sas ESD1 and ESD2 respectively.

Install and run ParaniWizard.

connection is made, DCD signal will be in the OFF state. When disconnecting a Bluetooth
connection, DCD signal will be in the ON state.
Connection Module  low signal

A.1.4. RST Signal

RST signal will be used for setting the Parani-ESD to factory defaults. RST should be on 0V status
for at least 1 secondfor the reset to occur.

32

A.1.5. Pairing Signal (only for Parani-ESD100/110)

Parani-ESD100/110 provides a pairing signal input for instant configuration and automatic
connection to two Parani-ESDs. In this example, we will name the two Parani-ESDs as ESD1 and
ESD2.

Step 1. Turn off all the nearby Parani-ESDs
Step 2. Turnon ESD1 and ESD2 and hardware reset both of them by using RST signal.
Step 3. Set the pairing signal of ESD1 to a low state and hold the signal for 2 seconds.
Step 4. Set the pairing signal of ESD2 to a low state and hold the signal for 2 seconds. Set the

pairing signal of ESD2 to high state and hold the signal for 2 seconds. Now Set the pairing signal
of ESD2 to low state and hold it for 2 seconds

Step 5. Wait for ESD1 & ESD2 to connect to each other. It may take about 10 seconds to make a

connection. If there are many Bluetooth devices nearby, the connection time may increase.

Step 6. At this point your pair of Parani-ESD is configured to make automatic connection to each

other.

You can now use this pair of Parani-ESD’s like virtual serial cable.

* Note: During the pairing process, by way of the pairing signal, the Command Response will be
deactivated. Thus, the Parani-ESD will not send the response messages such as OK, Connect and
Disconnect.

Appendix C: S-Register

S-registers contains 52 parameters for the Parani-ESD. These are stored in flash memory and the
values will be saved unless hardware reset is executed. The value of S-register can be accessed and
changed with ATS command. Some S-registers not shown below are set to maximize the performance
of Parani-ESD. Thus it is not recommended to change these S-registers.
Change the value of S-register only in Standby status. Turn Parani-ESD off and on.

C.1. S1: Force to Reconnect (default 1)

S1=0, Parani-ESD in Mode1 does not try to reconnect when disconnected.
S1=1, Parani-ESD in Mode1 keepstrying to reconnect when disconnected.

C.2. S3: Stream UART Policy (default 0)

S3=0, the priority of UART streaming is throughput.
S3=1, the priority is latency, which minimizes the delay of data transmission. This is useful in case of

transmitting very small data quickly.
When this value is 1, in order to minimize latency, Parani-ESD sends the received data immediately.
When this value is 0, the Parani-ESD maximizes throughput, the Parani-ESD stores received data for
a short time and sends a large data packet. If the packet length is less than 100 bytes, having latency
being the priority is recommended. If the packet length is more than 100 bytes, having throughput as
the priority is recommended. Also, if you want to use high baudrate, throughput priority will be more
effective. Just for reference,the buffer length for receiving data is 2 Kbytes.

C.3. S4: Enable Remote Name Query (default 1)

S4=0, Parani-ESD will query only the BD address. This speeds up the inquiry process.
S4=1, Parani-ESD will query the BD address, device name and class of device.
When this value is 1, Parani-ESD finds not only BD address but also friendly name. When this value is
0, Parani-ESD finds only BD address. When set to 0 this will make queries much faster. When using
the pairing button, finding friendly name will be omitted automatically.

C.4. S6: Enable Low Power Mode (default 0)

S6=0, deactivate Low Power Mode.
S6=1, activate Low Power Mode.
This value decides whether Parani-ESD works in Low Power Mode or not. When this value is 0,
Parani-ESD works only in active power mode. When Parani-ESD works in Low Power mode, delay in
transferring data may occur.

C.5. S10: Enable Response Message (default 1)

S10=0, Parani-ESD does not send response messages to the host system.
S10=1, Parani-ESD sendsresponse messages to host system.
This value decides whether Parani-ESD sends response messages such as OK, ERROR, CONNECT,
DISCONNECT or not. When this value is 0, Parani-ESD will not send any response messages. If the
response messages conflicts with your host programs or devices that is connected to Parani-ESD,
change this value to 0.

C.6. S11: Enable Escape (default 1)

S11=0, Parani-ESD does not allow escape sequence characters. The operation status of Connect

cannot be changed to Standby. Since the Parani-ESD skips the process of detecting escape

sequence characters, more efficient data transmission can be had.
S11=1, Parani-ESD allows for the escape sequence charactesr. Whenever it is needed, the Connect

49

status can be changed to Standby.

C.7. 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.8. S13: Enable DCD Signal (default 1)

S13=0, DCD signal off
S13=1, DCD signal on

C.9. S14: Enable DTR Transfer (Only ESD100/110, default 1)

S14=0, DTR/DSRsignal is transferred in a loop-back fashion..
S14=1, DTR signal is transferred to DSR of remote device.

C.10. S15: Enable Disconnect by DTR (Only ESD100/110, 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: Faster Connection (default 0)

S22=0,none
S22=1,page scan
S22=2, inquiry scan
S22=3, page/inquiry scan

C.12. S23: Intercharacter Timeout Setting (default 0)

S23=0 : Not used
S23=1 : 1 x S26
S23=2 : 10 x S26
S23=3 : 100 x S26
Connecting time is average 1.5sec faster than normal mode.

C.13. S24: Maximum Number of Inquiry Result (default 10)

The maximum number of inquiry list can be controlled. This value is up to 15.

C.14. S26: Intercharacter Timeout (default 0)

S23=1 x S26=50 : Timeout-> 50msec
S23=2 x S26=50 : Timeout-> 500msec
S23=3 x S26=3 : Timeout-> 300msec

Inter Character Time Out * Optimal Value(S23 x S26)
50ms 180
100ms 235
200ms 340

* When 10 bytes data are sent every intercharacter timeout, they are sent separately by 10 bytes at

50

the optimal value. If the intercharater timeout is set below the optimal value, the data will be put

together and sent by 20, 30, 40 bytes or more.

C.15. S28: Escape Sequence Character (default 43)

The decimal number of the ASCII code of escape sequence character can be controlled. The initial

value is 43, the ASCII code of ‘+’.

C.16. S31: Page Timeout (default 300)

This is the timeout in secondsto attempt connection with the ATD command. After this timeout expires,
the Parani-ESD will restart automatically. If this value is 0, Parani-ESD will attempt to connect without
restarting

C.17. S33: Inquiry Timeout (default 30)

This is the timeout in secondsto execute inquiry scan.

C.18. S37: Supervision Timeout (default 16000)

This is the timeout in 625μsec to presume disconnection, which is set to 16000 initially.
(16000625μ sec=10sec)
The smaller the value becomes, the more quickly Parani-ESD can detect an abnormal disconnection.
But when the communication is suspended, it may be regarded as disconnection.

C.19. S46: BD Address of Last Connected Device

This saves the BD address of the Bluetooth device connected most recently.

C.20. S47: Select Low Power Mode (default 0)

S47=0, Select Park Mode
S47=1, Select Sniff Mode
When this value is 0, Parani-ESD works only in park mode. When Parani-ESD works in park mode,
delay in transferring data may occur. And if the value is 1, Parani-ESD works in sniff mode. Parani­ESD worksalways low power mode but the data will be put together.

C.21. S48: Low Power Max Interval (default 2048)

This is the max interval value to use low power mode, which is set to 2048 initially. (2048 x 625μsec =
1280msec)

C.22. S49: Low Power Min Interval (default 800)

This is the min interval value to use low power mode, which is set to 800 initially. (800 x 625μ sec =
500msec)
When sniff mode, a small sniff interval increases power consumption, a large sniff interval increases
latency. For low power modes, typical values of the sniff interval are from about 0.5 second to 1.28
seconds

C.23. S50: Low Power Sniff Attempt (default 8)

This is the sniff attempt value, which is set to 8 initially. (8 x 0.625μsec = 5msec)

51

C.24. S51: Low Power Sniff Timeout (default 8)

This is the sniff timeout value, which is set to 8 initially. (8 x 0.625μ sec = 5msec)
The sniffing slave listens for traffic during the sniff slots determined by the sniff attempt parameter. If
no message addressed to the sniffing slave is received, the sniffing slave ceases listening for packets.
If a message with the sniffing slave’s active member address is received, it continues listening for
further sniff timeout slots after the sniff slot.

C.25. S52: Low Power Park Timeout (default 5)

This is the park timeout value, which is set to 5 initially. (5sec)
During no data transmission in park timeout, Parani-ESD can be in low power mode to save the power.
It takes a few seconds to wake the Parani-ESD out of low power mode.

Appendix D: Trouble Shooting

D.1. No Data Transmission

D.1.1. Device Settings

Check whether the Baud rate of Parani-ESD matches that of its host equipment.
Check whether the host equipment of Parani-ESD uses Hardware Flow Control. Parani-ESD is initially
set to Use of Hardware Flow Control. If your host equipment does not use Hardware Flow Control,
please disable the Hardware flow control option by ParaniWIN orAT command.

D.2. Data Loss or Malfunctioning

D.2.1. Hardware Flow Control

When transmitting large amounts of data with No Hardware Flow Control, Parani-ESD may clear the
data buffer unexpectedly. The possibility becomes greater as the RF transmission environment
becomes worse.

D.2.2. Response Message

AT response messages from the Parani-ESD may affect the host system unexpectedly. Do not use
Parani-ESD If your applications cannot allow for this wireless time delay.

D.3. Transmission Delay

D.3.1. RF Processing Delay

It takes 30msec approximately for a Parani-ESD to complete a data transmission to the other
Bluetooth device. This time delay cannot be reduced and may enlarge as the RF transmission
environment becomes worse. Do not use Parani-ESD If your applications cannot allow for this time
delay.

D.3.2. RF Transmission Environment

If there are many Bluetooth devices working in a small area and/or the RF communication distance is
too great and/or there are some obstacles affecting RF performance, the Parani-ESD repeats the
transmission packet by packet due to interferences and/or low RF performance. This may lead to
increased data transmission time delays.
