1. Introduction
1.1. Overview
IW07 is a terminal device for wireless serial communication using Bluetooth 2.0+EDR technology that
is an international standard of short range wireless communications. IW07 can communicate with
other Bluetooth devices; user may connect other Bluetooth devices that support the Serial Port Profile.
The working distance of IW07 with default antenna is 100m
IW07 has a compact design, which allows it to be placed conveniently into various devices or
equipment. Its detachable antenna has the ability to optimize the quality and distance of wireless
communications.
IW07 supports FHSS (Frequency Hopping Spread Spectrum), which is a technique, native to
Bluetooth that allows the IW07 minimize radio interference while decreasing the likelihood of over-air
hijacking. IW07 also supports authentication and Bluetooth data encryption.
IW07 can be configured and controlled by a set of AT commands. Users can easily configure IW07 on
a terminal program, such as HyperTerminal, and configure for wireless communication without
modifying user’s existing serial communication program. User friendly ParaniWIN can also be used for
easy setup on Microsoft Windows.

Note *:
Bluetooth v2.0 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 IW07 also requires some settings for Bluetooth. For
getting the most out of IW07, 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.
IW07 has 4 operation modes as follows. Each mode can be identified with LED indicators as
illustrated in next section.
Table 3-1 The IW07 Operation Modes
Mode
Description
Mode0
In this mode, there is no response when power on or software reset, and IW07 is just waiting
for AT command input. Neither master nor slave is assigned to IW07 in mode0. User can
change the configuration parameters of IW07 in this mode.
IW07 must be in Mode0, when it is directly controlled by AT commands.
The factory default is set to Mode0.
Mode1
IW07 tries to connect the last connected Bluetooth device.
IW07 in Mode1 is to be a master and tries to connect the last connected Bluetooth device.
IW07 always stores the BD address of the Bluetooth device to which IW07 has connected last.
When IW07 is initially used or after hardware reset, there is no BD address stored in IW07. In
this case, Mode1 will not be able to work properly. The mode change to Mode1 can be made
after IW07 succeeds to connect to one other Bluetooth device. Once changed to Mode1, IW07
will try to connect automatically the last connected Bluetooth device whenever the unit is
powered on or software reset.
IW07 in Mode1 cannot be discovered or connected by other Bluetooth devices.
Mode2
IW07 is waits for a connection from the last connected Bluetooth device.
IW07 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 IW07, the mode change
from other operation modes to Mode2 is not work properly. Once changed to Mode2, IW07 will
wait for the connection from the last connected Bluetooth device whenever the unit is powered
on or software reset.
IW07 in Mode2 cannot be discovered or connected to Bluetooth devices other than the last
connected device.
Mode3
IW07 is waiting for the connection from any other Bluetooth devices. In Mode 3 the IW07 is
discoverable and can be connected to by other Bluetooth devices.
3.2. LED Indicators
RS232-Tx and RS232-Rx LED will flash accordingly when data is transmitted. For small data
15
transmissions, it may be hard to recognize the quick flashing action of the LED. Charge Led and Low
battery LED will be off, if you don’t use battery pack.

The values in box are the factory defaults. The flow control setting is configurable only through dip
switch.
3.4. Data Bit
IW07 supports only 8 data bit. In the case of 7 data bit and even/odd parity, use SD 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.
3.5. Hardware Flow Control
IW07 plugged into its host system transmits data from host to the other side Bluetooth device. This
16
data is saved temporarily in the internal buffer of IW07 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 IW07 malfunction consequently. In order to prevent this buffer overflow, IW07 works
as follows.
When using hardware flow control, IW07 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 IW07 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.
3.6. Reset to Factory Defaults
To set all the configuration settings to its factory default parameters, press the reset button, depicted in
Fig. 3-1. Press and hold (for at least 1 sec) the reset button with a narrow pointed tool like paper clip.
Reset works only when power is on.
3.7. Dipswitch
With the combination of 4 slot dipswitches, baud rate and hardware flow control can be set.
Figure 3-1 The IW07 Dipswitch
Upper 3 dipswitches are used for setting the baud rate, and bottom dipswitch is used for setting
hardware flow control option. If the baud rate needs to a baud rate not shown below, ParaniWIN or
terminal program should be used to set these speeds. To set a baud rate not shown below the
dipswitches should be in the S/W Config setting. When in the S/W Config setting the baud rate will go
back to 9600 as default.

between two IW07s. In this example we will refer to the two IW07s as SD1 and SD2. (Only single
connection mode)
Step 1. Turn on SD1 and SD2 and reset both of them by pressing Factory Reset Button.
Step 2. Press the Pairing Button of SD1 for 2 seconds until Mode LED blinks 3 times every 3 seconds.
Keep the power ON.
Step 3. Press the Pairing Button of SD2 for 2 seconds until Mode LED blinks 3 times every 3 seconds.
Now press again the Pairing Button for 2 seconds until Mode LED blinks every second.
Step 4. Wait for SD1 & SD2 to connect to each other until the Connect LED’s of SD1 and SD2 blink
every 1 second. It takes about 10 seconds to make a connection. If there are many Bluetooth
devices nearby, it may take longer.
Step 5. Turn SD1 off and on. Mode LED blinks twice in green every 3 seconds.
Step 6. Turn SD2 off and on. Mode LED blinks in green every second.
Step 7. Now SD1 and SD2 are configured to make automatic connection to each other, whenever they
are powered on.
Using a pair of IW07 in this fashion is similar to that of using a wireless serial cable.
* Note: When using the pairing buttons, the Command Response option will be deactivated
automatically. The IW07 will not send the response messages such as OK, Connect and Disconnect.

When the ParaniWin software is able to access the IW07 properly, the icons in the left side window
come will become available for use.
In device configuration window, hardware reset can be executed or operation mode and RS232 can
be configured as well. Security option also can be configured in this window.
Figure 3-6 Device Setting Window
IW07 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 IW07 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
IW07 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.
IW07 has 4 response messages, ‘OK’, ‘ERROR’, ‘CONNECT’, and ‘DISCONNECT’. In some cases,
23
these responses can affect the host system unexpectedly. To prevent this, user can set the Command
response to ON or OFF.
For IW07, hardware flow control can be configured only by dip switch. And parity, stop bit can be
configured only SW config mode. Thus H/W Flow Control option will not work in this case. When the
dipswitch value isn’t ATcommand mode, the Baud Rate menu will be disabled.
Click [Apply] button to apply any changes made to the IW07.
Connection(out) icon will show the following window to search and connect other Bluetooth devices.

4.4. Notes
When large data exchange occurs in Multi-drop mode without flow-control enabled, the master unit
may experience data loss. It may also experience occasional disconnections and/or system rebooting
especially when bi-directional communication happens. It is strongly recommended to perform
extensive performance test before any real world field applications.
The master unit would try to connect all slave units specified by S-register 46, 54, 55 and 56. If non-
existing or inactive slave addresses are entered in these S-registers, the overall performance will
degrade due to frequent connection trials to non-existing/inactive slaves. It may also force
disconnections for overall performance and outputs disconnect messages repeatedly.
Node-switching mode provides nearly equivalent performance as single connection mode. It is always
recommended to use flow-control for both of Multi-Drop Mode and Node Switching Mode.

B.3.13. +++
Response
OK
Purpose
Convert the operation status of ‘Connect’ to ‘Standby’
Description
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-SD 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’. Notice
that Parani-SD holds data transmission when it encounters ‘+’, until receiving next
character.
‘+’ is an escape sequence character by default, which is changeable by AT+SETESC.
It can’t use for remote configuration mode.
* Caution : In low power mode, you cannot change online status to command waiting status
by using the ‘+++’ string. Entering the ‘+++’ string during low power mode and online status
44
may entail unexpected errors.
B.3.14. AT+SETESC,nn

Appendix C: S-Register
S-registers contain 52 parameters for the Parani-SD Series. 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-SD Series. Thus it is not recommended to change these S-registers.
Changing the values of S-register can only be done in the Standby mode. Turn Parani-SD off and on.
C.1. S1: Force to Reconnect (default 1)
S1=0, Parani-SD in Mode1 does not try to reconnect when disconnected.
S1=1, Parani-SD in Mode1 keeps trying 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-SD sends the received data immediately.
When this value is 0, the Parani-SD maximizes throughput, the Parani-SD 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 baud rate, 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-SD will query only the BD address. This speeds up the inquiry process.
S4=1, Parani-SD will query the BD address, device name and class of device.
When this value is 1, Parani-SD finds not only BD address but also friendly name. When this value is
0, Parani-SD 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-SD works in Low Power Mode or not. When this value is 0, Parani-
SD works only in active power mode. When Parani-SD works in Low Power mode, delay in
transferring data may occur.
C.5. S10: Enable Response Message (default 1)
S10=0, Parani-SD does not send response messages to the host system.
S10=1, Parani-SD sends response messages to host system.
This value decides whether Parani-SD sends response messages such as OK, ERROR, CONNECT,
DISCONNECT or not. When this value is 0, Parani-SD will not send any response messages. If the
response messages conflicts with your host programs or devices that is connected to Parani-SD,
change this value to 0.
C.6. S11: Enable Escape (default 1)
S11=0, Parani-SD does not allow escape sequence characters. The operation status of Connect
cannot be changed to Standby. Since the Parani-SD skips the process of detecting escape
sequence characters, more efficient data transmission can be had.
52
S11=1, Parani-SD allows for the escape sequence character. Whenever it is needed, the Connect
status can be changed to Standby.
C.7. S12: Clear Data Buffer When Disconnected (default 1)
S12=0, Parani-SD does not clear the data buffer received from host system when disconnected.
S12=1, Parani-SD 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 (default 1)
S14=0, DTR/DSR signal 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 (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
Connecting time is average 1.5sec faster than normal mode.
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
C.13. S24: Maximum Number of Inquiry Result (default 15)
The maximum number of inquiry list can be controlled. If value is 0, maximum number of
inquiry list is limitless.
C.14. S26: Intercharacter Timeout (default 0)
This value describes time interval between characters used to separate the data from serial port. If
there is no more data coming from serial port in this value, data is sent to client.
S23=1 x S26=50 : Timeout-> 50msec
S23=2 x S26=50 : Timeout-> 500msec
S23=3 x S26=3 : Timeout-> 300msec
Intercharacter Timeout
* Optimal Value(S23 x S26)
53
* When 10 bytes data are sent every intercharacter timeout, they are sent separately by 10 bytes at
the optimal value. If the intercharater timeout is set below the optimal value, the date 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 20)
This is the timeout in seconds to attempt connection with the ATD command. If this value is 0, Parani-
SD will attempt to connect without restarting. It must set at 5 second units.
C.17. S33: Inquiry Timeout (default 30)
This is the timeout in seconds to execute inquiry scan.
C.18. S37: Supervision Timeout (default 5)
This is the timeout to presume disconnection, which is set to 5 seconds initially. The smaller the value
becomes, the more quickly Parani-SD can detect an abnormal disconnection. But when the
communication is suspended, it may be regarded as disconnection. This value should be greater than
the Slave Disconnect Timeout(S57). (Slave unit depends on the value of master unit.)
C.19. S43: COD (default 001F00)
This value describes the sort of the bluetooth device and is editable.
C.20. S44: COD Filter (default 0)
This value is used to filter the sort of the bluetooth devices on inquiring. All the bluetooth devices are
inquired in case of 0. In case of 3E0100, bluetooth devices with COD 3E0100 are inquired.
C.21. S45: Inquiry Access Code (default 0x9E8B33)
Inquiry access code is used during inquiry state. The reserved IAC addresses are 0x9E8B00 ~
0x9E8B3F. The general inquiry IAC is 0x9E8B33.
Parani-SD is able to find the Bluetooth devices that are configured as the same IAC
C.22. S46: BD Address of Last Connected Device
This saves the BD address of the Bluetooth device connected most recently in single connection
mode. This saves the Task1 BD address of the Bluetooth device connected most recently in a multiple
connection mode.
50ms
180
100ms
235
200ms

54
C.23. S48: Low Power Max Interval (default 5000)
This is the max interval value to use low power mode, which is set to 5000 initially. (5000 x 625μsec =
3125msec)
C.24. S49: Low Power Min Interval (default 4500)
This is the min interval value to use low power mode, which is set to 4500 initially. (4500 x 625μsec =
2812msec)
A small interval increases power consumption, a large interval increases latency.
C.25. S52: Low Power Timeout (default 5)
This is the low power timeout value, which is set to 5 initially. (5sec)
During no data transmission in the timeout, Parani-SD will be in low power mode to save the power.
Therefore, it takes a few seconds to wake the Parani-SD out of low power mode.
C.26. S54: BD Address of Last Connected Device
This saves the Task2 BD address of the Bluetooth device connected most recently in a multiple
connection mode.
C.27. S55: BD Address of Last Connected Device
This saves the Task3 BD address of the Bluetooth device connected most recently in a multiple
connection mode.
C.28. S56: BD Address of Last Connected Device
This saves the Task4 BD address of the Bluetooth device connected most recently in a multiple
connection mode.
C.29. S57: Slave Disconnect Timeout (default 3)
This S57 register value defines the time period in seconds that a master unit waits in case a slave unit
does not receive the data sent from the master. For this time period, the master unit will not send data
to all slave units if any slave unit does not receive the data. If the slave unit does not receive the data
after this time period elapses, the master unit will disconnect the connection with the problematic slave
unit. The value should be greater than 0 and smaller than the Supervision Timeout(S37).
C.30. S58: MAX TX POWER (default 0)
This value describes the peak output power. Setting this causes rebooting and applying. (There can
be a little deviation depending on the each device.)

This value shows the current slave number in communication. The value is automatically stored when
the slave is selected for communication. This value can also be set by user so the master unit
connects to a specific slave to connect first in case the master unit reboots. The value range is 0~4. 0
means the maser unit never connected to a slave. The master will connect to a slave whatever
responses first.
C.32. S60: Reconnect Time Interval (default 5)
This value defines reconnect time interval in case a slave is disconnected in multiple connection mode.
The actual reconnect time interval will be the value multiplied by two in seconds. For example, if the
value is set to 5, the reconnect time interval will be 10 seconds. The value should be greater than or
equal to 5. The master unit will only try to reconnect when its mode is set to Mode1.

Appendix D: Trouble Shooting
D.1. No Data Transmission
D.1.1. COM Port Settings
Check whether the Baud rate of Parani-SD matches that of its host equipment.
Check whether the host equipment has a Data bit setting of 8. Parani-SD supports only 8 Data bit
settings. If your host equipment uses 7 Data bit and even or odd parity, it may work with a 8 Data bit
and No parity setting. This is valid only when both DCE devices are the Parani-SD. In this case, set
both Parani-SDs to 8 Data bit and No parity. If one of DCE devices is another Bluetooth device such
as Bluetooth USB dongle,7 bit data configurations will not work.
Check whether the Parity and Stop bit of Parani-SD match those of your host equipment. Parani-SD
supports No parity, Even parity and Odd parity, 1 and 2 Stop bit configurations.
Check whether the host equipment of Parani-SD uses Hardware Flow Control. Parani-SD 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 way of the dipswitch.
Parani-SD does not support RS-232 break signal.
D.1.2. Pin Assignment
Parani-SD is a DCE device. If your host equipment is DTE, plug Parani-SD directly to the host
equipment or use straight RS-232 cable. If your host equipment is DCE, use will need to use a cross
over RS-232 cable (Null modem cable) or a Male to Male DB9 Null Modem adapter.
D.2. Data Loss or Malfunctioning
D.2.1. Hardware Flow Control
When transmitting large amounts of data with No Hardware Flow Control, Parani-SD may clear the
data buffer unexpectedly. The possibility becomes greater as the RF transmission environment
becomes worse.
D.2.2. Response Message
The messages of Parani-SD response may affect the function of host system. Set ATS10=0 not to send Parani-
SD 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 approximately for a Parani-SD 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-SD 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-SD repeats the
transmission packet by packet due to interferences and/or low RF performance. This may lead to
increased data transmission time delays.
