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.

It is possible to check the available serial port at the Device Manager of the Panel as shown in Figure 2-4. Figure 2-4 USB Serial Port

3. Configuration 3.1. Operation Modes In addition to the serial port configurations the Parani-SD1000U also requires some settings for Bluetooth. For getting the most out of Parani-SD1000U, 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-SD1000U has 4 operation modes as follows. Each mode can be identified with LED indicators as illustrated in next section. Table 3-1 The Parani-SD1000U Operation Modes Mode Description Mode0 In this mode, there is no response when usb port connect or software reset, and Parani-SD1000U is just waiting for AT command input. Neither master nor slave is assigned to Parani-SD1000U in mode0. User can change the configuration parameters of Parani-SD1000U in this mode. Parani-SD1000U must be in Mode0, when it is directly controlled by AT commands. The factory default is set to Mode0. Mode1 Parani-SD1000U tries to connect the last connected Bluetooth device. Parani-SD1000U in Mode1 is to be a master and tries to connect the last connected Bluetooth device. Parani-SD1000U always stores the BD address of the Bluetooth device to which Parani-SD1000U has connected last. When Parani-SD1000U is initially used or after hardware reset, there is no BD address stored in Parani-SD1000U. In this case, Mode1 will not be able to work properly. The mode change to Mode1 can be made after Parani-SD1000U succeeds to connect to one other Bluetooth device. Once changed to Mode1, Parani-SD1000U will try to connect automatically the last connected Bluetooth device whenever the unit is connect to usb port or software reset. Parani-SD1000U in Mode1 cannot be discovered or connected by other Bluetooth devices. Mode2 Parani-SD1000U is waits for a connection from the last connected Bluetooth device. Parani-SD1000U 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-SD1000U, the mode change from other operation modes to Mode2 is not work properly. Once changed to Mode2, Parani-SD1000U will wait for the connection from the last connected Bluetooth device whenever the unit is connect to usb port or software reset. Parani-SD1000U in Mode2 cannot be discovered or connected to Bluetooth devices other than the last connected device. Mode3 Parani-SD1000U is waiting for the connection from any other Bluetooth devices. In Mode 3 the Parani-SD1000U is discoverable and can be connected to by other Bluetooth devices.

3.2. LED Indicators Serial-Tx and Serial-Rx LED will flash accordingly when data is transmitted. For small data transmissions, it may be hard to recognize the quick flashing action of the LED. Table 3-2 The Parani-SD1000U LED Indicators Indicator Mode LED Connect LED Mode 0 Green ┏━━━━━ Mode 1 Green (every 1 sec) ┏┓ Mode 2 Green (every 3 sec) ┏┰┓ Mode 3 Green (every 3 sec) ┏┰┰┓ Connected Green (every 1 sec) ┏┓ 3.3. Serial Ports The applicable settings for serial ports are as follows. Table 3-3 The Parani-SD1000U Serial Port Settings Serial Port Settings Values Baud rate 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, 230400, 460800, 921600 Data bite 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. The flow control setting is configurable only through dip switch. 3.4. Data Bit Parani-SD1000U 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 Parani-SD1000U 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-SD1000U 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-SD1000U malfunction consequently. In order to prevent this buffer overflow, Parani-SD1000U works as follows.

When using hardware flow control, Parani-SD1000U 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-SD1000U 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 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 SD1000U is connect to usb port. 3.7. Dipswitch With the combination of 4 slot dipswitches, baud rate and hardware flow control can be set. Figure 3-1 The Parani-SD1000U 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. Table 3-4 Baud rate Settings by Dipswitches Baud rate 2400 4800 9600 19.2K 38.4K 57.6K 115.2K S/W Config Table 3-5 Hardware Flow Control Settings by Dipswitches Hardware Flow Control Handshaking No Use Use * Note: You cannot set the Parani-SD1000U to a Baud rate of 1200 and 230K by way of the Dipswitch. Pairing Button Dip switch Reset

If you want to use them, to set these speeds, please configure the dipswitch to S/W Config setting and use ParaniWIN or AT commands. Please refer to ParaniWIN and Appendix A.3.4 (AT+UARTCONFIG, Baud rate,Paraty,Stopbit). 3.8. Pairing Button Parani-SD1000U provides Pairing Button for instant configuration without a PC to make an automatic connection between two Parani-SD1000Us. In this example we will refer to the two Parani-SD1000Us 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 connect to usb port. 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. SD1 disconnect to usb port and connect to usb port. Mode LED blinks twice in green every 3 seconds. Step 6. SD2 disconnect to usb port and connect to usb port. 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 connected to usb port. Using a pair of Parani-SD1000U 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 Parani-SD1000U will not send the response messages such as OK, Connect and Disconnect. Table 3-6 Pairing Process by Pairing Button SD1 Status LED SD2 Status LED 1.

Software and Utility This configuration software and utility for firmware update is included with the product, which also can be downloaded from http://www.senaindustrial.com Table 3-8 Configuration Software Software Purpose Operating System ParaniWIN Configuration MS Windows 98SE or Higher ParaniUpdater Firmware Update MS Windows 98SE or Higher 3.10. ParaniWIN ParaniWIN is a program that runs on Microsoft Windows for the configuration of Parani-SD1000U. Install ParaniWIN on your computer. Plug a Parani-SD1000U into the serial port of the computer and turn on the power. Run ParaniWIN. Figure 3-2 Serial Port Setting Set each option properly and click [Confirm]. If the settings of the Parani-SD1000U are different from the ParaniWin, an error message will pop up. If the Parani-SD1000U is in the status of connection, warning message will pop up. Then the current connection can be cancelled by [Disconnect] button on the main window.

Figure 3-3 Main Window Figure 3-4 Information Window Serial port settings can be changed by <Start Configuration> and <ParaniWIN Configuration> of ParaniWIN in the menu bar at upper left corner of the window without re-running the ParaniWIN program.

Figure 3-5 Menu Bar at Upper Left corner of ParaniWIN When the ParaniWin software is able to access the Parani-SD1000U 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. Security option also can be configured in this window. Figure 3-6 Device Setting Window Parani-SD1000U supports 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 Parani-SD1000U 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-SD1000U 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-SD1000U 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. For Parani-SD1000U, 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 Parani-SD1000U. Connection(out) icon will show the following window to search and connect other Bluetooth devices. Figure 3-7 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.

Figure 3-8 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-SD1000U 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-SD1000U to terminate the test. Connection(in) icon will show the following window, which enables the Parani-SD1000U to wait for a connection from another Bluetooth device.

4. Multiple Connection Mode 4.1. Overview Parani-SD1000U supports multiple connections up to 4 slave units. There are two types of multiple connection modes: Multi-Drop Mode and Node Switching Mode. MS1 S4S3S2 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. MS1 S4S3S2 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. On communication after connecting ATO1 – Communicating with #1 Slave +++ OK ATO000195000003 – Communicating with slave of BD 000195000003

4.2. Configuration All the slaves should be in the status of waiting for connection either in Mode 2 or Mode 3 and the master unit tries to connect to the slave units. The master unit needs to be configured to work in a multiple connection mode using AT+MULTI,x command, which makes master reboots after execution. Table 4-1 AT+MULTI,x AT+MULTI,0 Single Connection Mode AT+MULTI,1 Multi-Drop Mode AT+MULTI,2 Node Switching Mode Table 4-2 Configuration of a Multiple Connection Mode Manual Connection Automatic Connection ATD000195000001 CONNECT000195000001 +++ OK ATD000195000002 CONNECT000195000002 +++ OK ATD000195000003 CONNECT000195000003 +++ OK ATD000195000004 CONNECT000195000004 +++ ATS46=000195000001 OK ATS54=000195000002 OK ATS55=000195000003 OK ATS56=000195000004 OK AT+MULTI,1 or AT+MULTI,2 OK AT+BTMODE,1 After rebooted automatically master tries to connect to slaves After input the BD addresses of the slave units into 4 S-registers S46, S54, S55 and S56 and then set operation mode as MODE1, users can use multiple connection function. If S-registers have available slaves’ address, AUTO CONNECT message will be displayed following corresponding TASK. TASK1 OK – AUTO CONNECT TASK2 OK TASK3 OK – AUTO CONNECT TASK4 OK

4.3. AT Commands 4.3.1. AT+MULTI,n Select a multiple connection mode. Refer to Table 4-1 for descriptions. 4.3.2. AT+MLIST? It shows the current mode, the connection status and the BD addresses of slaves. 4.3.3. ATHx, ATHbdaddr Using the ATH command, connections with all slaves or only connections with specific slaves can be disconnected selectively Table 4-3 ATH ATH Disconnect all the slaves. ATHx (ATH1, ATH2, ATH3, ATH4) Disconnect the slave which belongs to the TASK x. ATHbdaddr (ATH000195000001) Disconnect the slave with specified BD address. 4.3.4. ATOx, ATObdaddr Using the ATO command, the communication status with the last active slave or a specific slave can be set to online (only in Node Switching Mode). Table 4-4 ATO ATO Communicate with the slave recently communicated. ATOx (ATO1, ATO2, ATO3, ATO4) Communicate with the slave which belongs to the TASK x. ATObdaddr (ATO000195000001) Communicate with the slave with specified BDaddress. at+mlist? CURRENT MODE: MULTI DROP TASK1 – 000195000001 TASK2 – 000195000002 TASK3 – DISCONNECT TASK4 - 000195000004 OK

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.

Appendix B: 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. B.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. B.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. B.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. B.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. B.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. B.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.

S11=1, Parani-SD allows for the escape sequence character. Whenever it is needed, the Connect status can be changed to Standby. B.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. B.8. S13: Enable DCD Signal (default 1) S13=0, DCD signal off S13=1, DCD signal on B.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. B.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. B.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. B.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 B.13. S24: Maximum Number of Inquiry Result (default 15) The maximum number of inquiry list can be controlled. This value is up to 15. B.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)

* 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. B.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 ‘+’. B.16. S31: Page Timeout (default 20) This is the timeout in seconds to attempt connection with the ATD command. After this timeout expires, the Parani-SD will restart automatically. If this value is 0, Parani-SD will attempt to connect without restarting. It must set at 5 second units. B.17. S33: Inquiry Timeout (default 30) This is the timeout in seconds to execute inquiry scan. B.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.) B.19. S43: COD (default 001F00) This value describes the sort of the bluetooth device and is editable. B.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. B.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 B.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 340

B.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) B.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. B.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. B.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. B.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. B.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. B.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). B.30. S58: 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. B.31. S59: 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 C: Trouble Shooting C.1. No Data Transmission C.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. C.2. Data Loss or Malfunctioning C.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. C.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. C.3. Transmission Delay C.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. C.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.
