1. Introduction

1.1. Overview

The IW05 is a Bluetooth OEM SMD/DIP module combining antenna for OEM manufactures who want

to implement Bluetooth functionality with their products cost effectively and also in timely manner.

IW05 has a built in antenna to lower the overall cost while benefit from the IW05’s field-proven

standard SPP firmware provided with no additional cost.

The IW05 supports Class2 Bluetooth transmission level for the shorter communication distance

typically ranges from 50m up to 300m. The IW05 supports Class1 Bluetooth transmission level for

longer communication distance typically ranges from 200m up to 1000m.

The IW05 is provided with Bluetooth v2.0+EDR compatible firmware runs internally for SPP (Serial

Port Profile) applications by default. The SPP firmware supports up to 4 simultaneous multiple

connections and is designed to work out-of-box for real world SPP applications such as POS (Point-of-

sales), industrial automation, remote metering and other various applications. Optionally, the IW05 can

be supplied with only software stack up to HCI level so entire Bluetooth stack runs on the host side for

the application such as USB dongles for computers or OEM manufacturers can even develop and

embed their own firmware into the IW05.

The IW05 is fully qualified with Bluetooth v2.0+EDR specification so OEM manufacturers can save

cost and time for overall OEM product certifications, which makes the IW05 ideal solution for larger

volume and cost sensitive applications.

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 IW05 requires also includes some settings for

Bluetooth. For getting the most out of IW05, 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.

IW05 has 4 operation modes as follows:

Table 3-1 The IW05 Operation Modes

Mode

Description

Mode0

In this mode, there is no response when power on or software reset, and IW05 is just waiting

for AT command input. Neither master nor slave is assigned to IW05 in mode0. User can

change the configuration parameters of IW05 in this mode.

IW05 must be in Mode0, when it is directly controlled by AT commands.

The factory default is set to Mode0.

Mode1

IW05 tries to connect the last connected Bluetooth device.

IW05 in Mode1 is to be a master and tries to connect the last connected Bluetooth device.

IW05 always stores the BD address of the Bluetooth device to which IW05 has connected last.

When IW05 is initially used or after hardware reset, there is no BD address stored in IW05. In

this case, Mode1 will not be able to work properly. The mode change to Mode1 can be made

after IW05 succeeds to connect to one other Bluetooth device. Once changed to Mode1, IW05

will try to connect automatically the last connected Bluetooth device whenever the unit is

powered on or software reset.

IW05 in Mode1 cannot be discovered or connected by other Bluetooth devices.

Mode2

IW05 is waits for a connection from the last connected Bluetooth device.

IW05 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 IW05, the mode change

from other operation modes to Mode2 is not work properly. Once changed to Mode2, IW05 will

wait for the connection from the last connected Bluetooth device whenever the unit is powered

on or software reset.

IW05 in Mode2 cannot be discovered or connected to Bluetooth devices other than the last

connected device.

Mode3

IW05 is waiting for the connection from any other Bluetooth devices. In Mode 3 the IW05 is

discoverable and can be connected to by other Bluetooth devices.

3.3. Data Bit

IW05 supports only 8 data bit. But if both master device and slave device are one of Parani-SD,

Parani-ESD or IW05 or Parani-MSP1000 series, Parani series devices can support 7 data bit and

even/odd parity by setting both Parani series devices to 8 data bit and none parity. But 7 data bit and

none parity cannot be supported even if both master device and slave device are Parani series

devices.

3.4. Hardware Flow Control

IW05 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 IW05 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 IW05 malfunction consequently. In order to prevent this buffer overflow, IW05 works

as follows.

When using hardware flow control, IW05 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 IW05 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. (Not support

flow control in Multi-Drop Mode.)

3.5. Remote Configuration

IW05 supports remote configuration. After connecting to the IW05 through Bluetooth, before sending

any other character, send three escape character (default :+). Then, the IW05 will enter remote

configuration mode and print “Please Enter Password”. You have to enter the password with

“AT+PASS” command within 2 minutes. After the password authentication, you are able to enter any at

command except “ATH”, “ATO”, “ATD”, “AT+BTSCAN”, “AT+BTINQ?” and “AT+BTCANCEL”. The

default password is “0000” and it is configurable with “AT+CHPASS” command.

Example of remote configuration mode.

Figure 3-5 Device Setting Window

IW05 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. IW05 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 IW05 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 IW05 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.

IW05 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 IW05.

START button.

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 IW05 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 any

time 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 IW05 to terminate the test.

4. Multiple Connection Mode

4.1. Overview

IW05 supports multiple connections up to 4 slave units. There are two types of multiple connection

modes: Multi-Drop Mode and Node Switching Mode.

S1 S4

S3S2

Figure 4-1 Multi-Drop Mode

In Multi-Drop Mode a master unit can connect to maximum 4 slave units at the same time and they

transfer data bi-directionally as in Figure 4-1.

S1 S4

S3S2

Figure 4-2 Node Switching Mode

In Node Switching Mode, the master unit maintains multiple connections with maximum 4 slave units

but only one connection with one slave unit is active and data is transferred as shown in Figure 4-2.

After connected to slave, master acts command mode. Active slave is selected by AT commands.

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.

Status of Bluetooth connection will be delivered to Host PC via UART_DCD signal. When Bluetooth

connection is made, UART_DCD signal will be set to low.

A.1.3. Factory Reset(FACTORY_RESET) Signal

Factory reset signal will be used for setting the IW05 to factory defaults. Factory reset signal should be

on 0V status for at least 1 second for the reset to occur.

A.1.4. Pairing (BT_MODE) Signal (Single Connection Mode Only)

IW05 provides a pairing signal input for instant configuration and automatic connection to two IW05s.

In this example, we will name the two IW05s as BCD1 and BCD2 In pairing mode.

Step 1. Turn on BCD1 and BCD2 and do factory default both of them by using RST signal.

Step 2. Set the pairing signal of BCD1 to a low state and hold the signal for 2 seconds.

Step 3. Set the pairing signal of BCD2 to a low state and hold the signal for 2 seconds.

Set the pairing signal of BCD2 to high state and hold the signal for 2 seconds. Now Set the pairing

signal of BCD2 to low state and hold it for 2 seconds

Step 4. Wait for BCD1 & BCD2 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 5. At this point your pair of IW05 is configured to make automatic connection to each other.

You can now use this pair of IW05’s like virtual serial cable.

* Note : During the pairing process, by way of the pairing signal, the Command Response will be

deactivated. Thus, the IW05 will not send the response messages such as OK, Connect and

Disconnect.

A.1.5. Flow Control(FC_CTRL) On/Off Signal

If user wants to set the status of hardware flow control option using AT+UARTCONFIG command,

FC_CTRL signal should be connected with UART_CTS signal.

If Hwfc parameter in AT+UARTCONFIG command is set to 1, FC_CTRL signal is set to high and then

hardware flow control is enabled. And if Hwfc parameter in AT+UARTCONFIG command is set to 0,

FC_CTRL signal is set to low and then hardware flow control is disabled.

A.1.6. Bluetooth Status LED(STATUS_LED0, STATUS_LED1) Signal

<STATUS_LED0>

If any Bluetooth device is connected, this signal is set to high during 150msec periodically

after low status during 1 sec.

<STATUS_LED1>

When the connection status is Standby, this signal is set to high.

When the connection status is Pending, this signal is toggled 3 times periodically after low

status during 1 sec.

When the connection status is Connect, this signal is set to low.

A.1.7. Reset Signal

IW05 can be reset from one of following sources:

- RESETB pin

- Power on reset

- UART break character

- Software configured watchdog timer

The RESETB pin is an active low signal and is internally filtered using the internal low frequency clock

oscillator. A reset will be performed between 1.5 and 4.0ms following RESETB being active. So it is

recommended that RESETB be applied for a period greater than 5ms.

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 IW05 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 IW05 holds data transmission when it encounters ‘+’, until receiving next character.

‘+’ is an escape sequence character by default, which is changeable by AT+SETESC.

* 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

may entail unexpected errors.

Appendix C: S-Register

S-registers contain 52 parameters for the IW05. 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 IW05.

Thus it is not recommended to change these S-registers.

Change the value of S-register only in Standby status. Turn IW05 off and on.

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

S1=0, IW05 in Mode1 does not try to reconnect when disconnected.

S1=1, IW05 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, IW05 sends the received data immediately. When

this value is 0, the IW05 maximizes throughput, the IW05 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, IW05 will query only the BD address. This speeds up the inquiry process.

S4=1, IW05 will query the BD address, device name and class of device.

When this value is 1, IW05 finds not only BD address but also friendly name. When this value is 0,

IW05 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 IW05 works in Low Power Mode or not. When this value is 0, IW05 works

only in active power mode. When this value is 1, IW05 will be in low power mode to save the power.

Therefore, it takes a few seconds to wake the IW05 out of low power mode.

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

S10=0, IW05 does not send response messages to the host system.

S10=1, IW05 sends response messages to host system.

This value decides whether IW05 sends response messages such as OK, ERROR, CONNECT,

DISCONNECT or not. When this value is 0, IW05 will not send any response messages. If the

response messages conflicts with your host programs or devices that is connected to IW05, change

this value to 0.

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

S11=0, IW05 does not allow escape sequence characters. The operation status of Connect cannot be

changed to Standby. Since the IW05 skips the process of detecting escape sequence characters,

more efficient data transmission can be had.

S11=1, IW05 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 0)

S12=0, IW05 does not clear the data buffer received from host system when disconnected.

S12=1, IW05 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 3)

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. This value can be set up to 15.

(If 0 is set, inquiry is performed without limitation on number of inquiry list.)

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

Inter Character Time Out

* 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 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 20)

This is the timeout in seconds to attempt connection with the ATD command. After this timeout expires,

the IW05 will restart automatically. If this value is 0, IW05 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 IW05 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.

IW05 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.

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, IW05 will be in low power mode to save the power.

Therefore, it takes a few seconds to wake the IW05 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. TS55: 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 is a

little deviation according to the devices.)

C.31. S59: Current Slave in Communication (default 0)

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.

D.2. Data Loss or Malfunctioning

D.2.1. Hardware Flow Control

When transmitting large amounts of data with No Hardware Flow Control, IW05 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 IW05 response may affect the function of host system. Set ATS10=0 not to send IW05 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 IW05 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 IW05. 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 IW05 repeats the

transmission packet by packet due to interferences and/or low RF performance. This may lead to

increased data transmission time delays.
