Brief Introduction Bluetooth RS232 adapter can be applied to all kinds of home appliances, equipment
(such as medical treatment equipment) and other electronic information products. As a cable replacement program, it can connect the single-chip processor or processor directly via using PnP mode to achieve the wireless data transmission among equipments transparently. Bluetooth RS232 adapter can be divided into Master device and Slave device which can be matched as one set. When the circuit of the Bluetooth RS232 adapter hardware is connected correctly and powered up, the master and slave device will establish a connection automatically and identify & memory each other. Then, the user's device can use the Bluetooth RS232 adapter as the same as using a serial cable. Bluetooth RS232 adapter can be used independently as well, excluding using by match. When users equipment equipped with a Slave Bluetooth RS232 adapter, other Bluetooth devices, such as Bluetooth PDA can search out this Bluetooth RS232 adapter and find out the services provided, and then establish connection and communicate with it through these services. For the communication of the users equipments, Bluetooth RS232 adapter can still be used as serial line. Bluetooth RS232 adapter provides a safety identification function. When users use safety identification, and only the authenticated equipment can realize communication. However, this process could be finished automatically if it is a pair of Bluetooth RS232 adapter.(Default Password: 1234) the equipments connects must be authenticated, http://www.oemblue.com/ info@oemblue.com 3 Chongqing Jinou Science &Technology Development Co., Ltd . Figure 1 shows that in the application of user devices A and B is a serial cable. Figure 2 shows that in the application of the user devices A and B are Bluetooth RS232 adapter, and between the two devices, it is the same to users devices and regarded as a serial line. Figure 3 shows the connection of Bluetooth RS232 adapter and other Bluetooth devices
(here is the connection situation of the Bluetooth PDA). Under this situation, for the user device, it is the same as the figure 1 and figure 2.

Under regular mode, all parameter is default. Between the devices it is 10 meters apart. It continuously sends data at the same time with 9600 baud rate. 4. Description of indicator and press-button There are three LED light on the RS232 adapter used to indicate the power state, connect status and master/slave mode of RS232 adapter. Using mode switchover press-button to change the working mode of adapter.(data mode or command mode) Indicator light:
The indicator light of adapter is red/green LED light, power state (red light), master/slave mode indicator (red light), connect condition indicator (green light). When the RS232 adapter is powered, the power state indicator light (red light) is always bright. If the master/slave mode instructor (red light) blinks every few seconds, it means the serial port adapter operates smoothly. We can judge this device is master device or slave device by looking the interval time of lights blinking. If blinking once every 3 seconds, it is slave device. If blinking once every 6 seconds, it is master device. If the connect state indicator (green light) extinguishes, that means it has established connection with other Bluetooth devices. If blinking, it means not establish connection. When not connecting, we can judge whether it memorize the address (that is whether matches other Bluetooth device of not) or not through the green lights blinking speed. If blinking quickly (twice every second), it means it has remembered the address; if blinking slowly (once every second) , it does not remember. For master device, it http://www.oemblue.com/ info@oemblue.com 6 Chongqing Jinou Science &Technology Development Co., Ltd . blinks once every 3 seconds when query. When matching, it blinks quickly four times every second; when connecting, blink once every second; after connecting, the indicator light extinguishes. When RS232 is working under the parameter setting condition, the master/slave indicator light and connecting state indicator light extinguish. Mode switch button: In data model state, press Cmd button, the two working condition indicator light of the RS232 adapter extinguish. At this time RS232 adapter works under the parameter setting condition and returns "+ OPEN: 0" from serial port. In parameter setting condition, RS232 adapter stops working, and can only set the parameter RS232 adapter. In parameter settings state, press the Cmd button and RS232 adapter exit parameter condition, matching, connecting, sending data etc.); but cannot set RS232 adapter parameters. After powering, it enters data mode state default. to work. (searching, and begin Figure 4 Outside View 1. RS232 Connector 2. DC Power Connector 3. Power Indicator Light (red) 4.

Description of Power Supply Condition There are two ways of power supply. The power socket of adapter can provide power and when connect on PC we can use this way. The power adapter specification of RS232 adapter is 6VDC, 500mA rated current. The second way is using DB9 seat to supply. It can be used on the device which developed by user. It can provide power only by plug in serial port. DB9-1, DB9-9 VCC, DB9-5 GND, 6V 100mA rated current. 7. Description of Serial Interconnection http://www.oemblue.com/ info@oemblue.com 8 Chongqing Jinou Science &Technology Development Co., Ltd. http://www.oemblue.com/ info@oemblue.com 9 Chongqing Jinou Science &Technology Development Co., Ltd. Notes: VCC/Nc says when use power sockets power-up, 1 and 9 pin is Nc. Using DB9 power-up, 1 and 9 pin connect VCC power supply. 8. Instructions After powering on, the power indicator light of the device should bright immediately and the other indicator light is blinking separately. After the factory, the default settings for the device are generally 9600bps , 8-N-1 communication mode and with flow control. It is a slave device and matching code is 1234. If there is need to modify parameter, please press the switch button to make RS232 adapter enter into parameter setting mode. Then the two blinked state indicator light extinguished. Setting related parameter through AT command or parameter setting tools, such as by the following parameter: master/slave device, baud rate, authentication, and bind address. If communicate between two RS232 adapter, you must set one adapter as a master device and the other as a slave device. And you can identify the status according to the blinking state of the master/slave indicator. Connecting several device need to enter command mode setting and the max memorized slave device number M (AT+ROLE= M\r\n). After returning data mode, it will automatically find and connect slave device around. http://www.oemblue.com/ info@oemblue.com 10 Chongqing Jinou Science &Technology Development Co., Ltd . Notes: The parameter is saving in Bluetooth. Therefore, even blackout, the parameter will keep the same number as the last time and will not lose. After modifying the parameter, please press the switch button again to make RS232 adapter enter into data model. Starting under the data state, if the master device do not memorize address, it will firstly search the nearby Bluetooth device. If querying the Bluetooth device, the master device will enter matched state. If authentication passes, the master device will memorize
(save) the address of this device and establish connection with this device. If memorized the address already, the master device connect the memorized device directly and will not query or match. The memorized address can be cleared by AT command and parameter setting tools. The slave device wait for the other devices query and connect. If two Bluetooth device connect successfully, connection indicator light (green light) extinguishes, and the master/slave mode instructions (red light) keep blinking. At this time, data can mutual communicate. For user device, it is like connecting with serial line and can receive data directly. Of course, for the mode of point to multi-point, the user need to structure data stream format by themselves to distinguish between some slave device. What should be paid special attention is that the serial flow control pin (CTS, RTS) is default effective. If not cancel flow control and the flow control pin is not disposed by the user program, the data can not be transmitted or can only transmit one-way after connecting. Once the device is connected, unless the signal is very bad to opposite sides Bluetooth disconnect automatically, our serial adapter will not disconnect automatically and the connection will always remain.

Bind address Whether you have bound the address of the other or not. Ticking() means that it can not connect with other devices after this matching & connection, but only limit the connection of this device . On the contrary, it is allowed to connect and match with any other devices. Whether to use authentication and encryption If selected, authentication, and data transmission will be encrypted. Password Password used to authenticate. (No more than 6 characters) the other device must enter a password before connecting to 9.3 Serial parameters Set data communication baud rates of the module and equipment. This baud rate is the baud rate of the module. Baud rate Parity Stop bit Support for no parity, odd parity, even parity Supports 1 stop bit, 2 stop bits 9.4 Energy-saving parameters and commands Connection interval The interval of each time you connect and scan, that is how often to allow the connection. Interval time = setting value 625us http://www.oemblue.com/ info@oemblue.com 14 Chongqing Jinou Science &Technology Development Co., Ltd . Connection lasts The duration of each time you connect and scan, that is the time you remain the connection state. Duration = setting value 625us Note: The duration of connection can not be longer than the interval. Inquiry Interval The interval of each time you Inquire and scan, that is how often to allow queries. Interval time = setting value 625us Inquiry lasts The duration of each time you Inquire and scan, that is the time you maintain the Inquiring & scanning state. Duration = setting value 625us Note: The duration of Inquiring can not exceed the interval of Inquiring. Sniff energy parameters Sniff has four parameters: maximum, minimum, try, timeout. Parameter value = set value 625us. When all the four parameters are 0, the sniff energy saving is forbidden, serial adapter run at full speed, the maximum data transmission speed is the highest, but power is high, and it is recommended to use when data is large. If allow to sniff energy, the serial adapter's power consumption will be reduced, and it is recommended to allow to sniff energy when the data is small, and it can reduce power consumption.such as:
Maximum = 800, minimum = 80, try = 8, timeout = 8. Binding Bluetooth address Inquiry the Bluetooth device address which matches with the Bluetooth module Inquiry Inquiry the current settings of the serial adapter. Set Default Set parameters to the serial adapter. However, it must be effective after the next start. Clear the address Revert the serial adapter to the default setting. However, it must be effective after the next start. Clear the address of the other Bluetooth device saved in the serial adapter. Once the serial adapter establish connection with a Bluetooth device, it will save its address. At next communication, the Bluetooth module can only communicate with this Bluetooth device and will not accept others addresses. You can clear the Bluetooth address by this tool, so that you can communicate with other devices. 9.5 Set After everything is ready, select the appropriate parameters from the connection setting dialog, such as communication port and flow control mode, and click the Connect button to establish a connection with the serial adapter. When the connection is successful, the system will display the Inquired current setting parameters of the serial adapter on the screen. If users need to modify some of these parameters such as baud rate, you can select the appropriate parameters, and after entering the appropriate values, click the Settings button to set. After setting, you can execute the Inquire command to check if the parameter settings are correct. After setting parameters, you must press the toggle button to enter data mode, and then http://www.oemblue.com/ info@oemblue.com 15 Chongqing Jinou Science &Technology Development Co., Ltd . the serial adapter can be used regularly. Note: Do not set the parameters often, or it will damage the chip. Description: This RS232 serial adapter can be customized according to user requirements 10. AT command Do not use "Configuration Tools" and the parameters of the RS232 adapter can also be Inquired / changed when send the AT command with serial port directly. Note: being the same as using Configuration Tools, it can be allowed to perform parameter setting command only when the serial adapter working under the "parameter setting state" (that is press Cmd button to enter). When Parameters are modified, you should make the serial adapter return to the data model, and then parameter settings take effect. Each command must make the two bytes (\r\n)carriage return and line feed ((ASCII codes are 0x0D, 0x0A) as the end sign, or command can not be identified The brackets "<>"outside of the parameter is added for convenient reading and the actual command is without the <>"

address not bind the When binding the address: For the slave device, if it has memorized the address, it is not allowed to be queried and matched and can be connected only by its memory devices; for the master device, if it has memorized the address, then it is trying to connect to the memorized device. When binding the address, once the device memorizes the address, the connection can only be established between the memorized device and itself, and not to establish a connection with other devices. Therefore, when binding the address, if you want to establish a connection with other devices, you must clear the memorized address. When not binding the address: the slave device can be queried and matched; the master device will clear the memorized addressed automatically and re-Inquire and match new equipment after failing to connect with the memorized device that up to a certain number. So, if you want to connect the permanent equipment, youd better bind the address. 15. Set/Inquire the memorized remoted Bluetooth device Command AT+RADDR=<addr>\r\n AT+RADDR?\r\n Response

Response
\r\n OK\r\n Show all commands Parameter List all the commands 1 After powering the module, the indicator of the Module doesnt blink. Check whether the power supply is correct. The correct power is positive inside and negative outside, from 6V. And the power is 100mA. If the power is supplied by DB9, the user needs to connect 1 or 9 pin to VCC and 5 pin to GND. 2 When there are multiple Bluetooth devices around, how to connect to the specified Bluetooth device?
Send AT+INQ command, and get the information of the Bluetooth device around Find the specified Bluetooth address according to the device name of INQRESU Send AT+RADDR=addr and memorized the information of the device Send AT+BIND=1command, and bind this device Send AT+ROLE=1, and set it as a single-point master device Sending AT+EXIT pushing command setting mode, the serial adapter will connect appointed Bluetooth device initiatively. 3 How to operate if want to connect with multiply devices at the same time The steps are about the same of the previous question, however:
Memorize multiply device information through the AT+RADDR=addrcommand;
Send AT+ROLE command to set the needed connected device number. Send AT+EXIT pushing command setting mode, the serial adapter will connect appointed Bluetooth device initiatively. http://www.oemblue.com/ info@oemblue.com 22 Chongqing Jinou Science &Technology Development Co., Ltd . 4 How the multipoint connections send and receive data? And what are the differences between the sending & receiving of multipoint and point-to -point connections?
The point to point sending and receiving data has no distinction of master device and slave device. But the multipoint connection has the distinction of master device and slave device. Each slave device can receive the data from a master device, but when send data from a slave device, only the master devices can receive it and other slave devices cannot receive this data. If multiply slave devices send data to the master device at the same time, the data sending from the serial port of the master device is intertwined and cannot distinguish which device it was sent from. 5 Can not set the parameters, or use the Configuration Tools displaying "connection timeout" when connects to the PC First, make sure if the indicator of the module in the data mode is blinking, and blinking means that the module works properly;
Make the module enter into the parameter setting mode. At this time, all of the indicators extinguish except for the power indicator;
Whether the serial port number of the setting tool (the Configuration Tools which JS&T provides) is the serial port you are using;
If use the serial line to connect with the PC, make sure whether the connection line is correct. Check the connection instruction of the serial port to learn about the connection method. 6 How to send AT command by your hand For most AT commands are not given in the Configuration Tools, it can only send through entering commands by hand when necessary. The steps are as follows:
Select a serial communication software (such as HyperTerminal or serial debugging assistant) to open the linked serial port. The serial port parameters under the parameter setting state are always configured to 9600bps and 8-N-1, and they have nothing to do with the serial parameters of the data communication which the AT command set. Press the toggle key to make the device enter into the parameter setting state. The blinking indicator extinguishes and the serial port should receive "+ OPEN: x\r\n ", and x as the current number of the memorized devices. Then you can send commands. What need to be noted is that all commands are end with CRLF ""\r\n ". All the commands will return
"\r\nOK\r\n " to response after sending and receiving correctly. If returns "\r\nERROR\r\n
" , please check whether the sending is correct. For example: sending a test command AT\r\n should send the 4 bytes AT\r\n. The Bluetooth returns \r\nOK\r\n after receiving properly. http://www.oemblue.com/ info@oemblue.com 23 Chongqing Jinou Science &Technology Development Co., Ltd . 7 Two serial adapter can not connect with each other Use Configuration Tools to inquiry and confirm whether one of the 2 modules is a Master device, the other one is a Slave device; whether the passwords and Category Codes of the two modules are the same, and if they are not, you should use the Configuration Tools to modify them into a same value. Whether the master device has memorize other modules address. If it is, please remove it. Besides, please check whether there are other Bluetooth setting or not. If there are, please close it. Whether the module has set the Bind Address option and connected with other devices. If it is, please remove the Match Setting addresses first. Because, for the Slave device, it is not allowed to be inquired and matched and only can be connected with its memorized devices if it has memorized the address; for the Master device, it will try to connect with its memorized devices all the time if it has memorized the addresses. 8 Why PC, USB Dongle can not find the serial adapter?
Firstly, ensure whether the serial adapter be set as a Slave device. For the serial adapter, the master device can not be found by other devices. Whether the adapter has set the Bind Address option and connected with other devices. If it is, please remove the Match Setting addresses first. Because, for the Slave device, it is not allowed to be inquired and matched and only can be connected with its memorized devices if it has memorized the address. 9 Why PC USB Dongle and serial adapter can not realize data communication or only communicate by one-way data communication?
First, make sure whether the two devices establish a connection, judging by looking at whether the Link indicator of the Bluetooth extinguish;
Check whether the serial cable connection is correct Whether the serial port of the using serial adapters application program of the using the serial port is the same of the serial port parameter of the adapters configuration. If the serial adapter has set the flow control, PC-side application should be selected for hardware flow control or CTS / RTS flow control; if connect to MCU, MCU should also process CTS and RTS pin in accordance with the RS232 protocol. If determines not to use flow control, use " AT+FLOWCONTROL\r\n " command to cancel it. If communicates large amounts of data with high-speed, it is strongly recommended to use flow control function, or it may cause data loss or a adapter reset. http://www.oemblue.com/ info@oemblue.com 24 Chongqing Jinou Science &Technology Development Co., Ltd . 10 How to communicate with PDA?
Firstly you need to set parameter of PDA and adapter and to make sure it must be the mode of one master and one slave. What need to be paid attention is the port setting of PDA. Taking WIN CE as an example, Bluetooth serial port settings are divided into the two serial ports: push and pop, if the module connects with the mobile phone as a master device initiatively, use the push port; If the module is connected by the mobile phone as a slave device initiatively, then use the pop port. 11 How to communicate with Bluetooth mobile phone?
The general Bluetooth mobile phone can not connect the serial service of other Bluetooth devices initiatively because they do not have serial service menu which can connect serial port. If the user want to realize serial port connect between Bluetooth mobile phone and adapter, they can set adapter as master device and connect Bluetooth mobile phone initiatively. But if need data communicate with adapter module, the user need to write by themselves generally or ask for serial communication software, which can be used on mobile phone, from mobile phone producer. 12. Appendix 12.1 Equipment Type Number The Class of Device/Service (CoD) field has a variable format. The format is indicated using the
'Format Type field' within the CoD. The length of the Format Type field is variable and ends with two bits different from '11'. The version field starts at the least significant bit of the CoD and may extend upwards. In the 'format #1' of the CoD (Format Type field = 00), 11 bits are assigned as a bit-mask (multiple bits can be set) each bit corresponding to a high level generic category of service class. Currently 7 categories are defined. These are primarily of a 'public service' nature. The remaining 11 bits are used to indicate device type category and other device-specific characteristics. Any reserved but otherwise unassigned bits, such as in the Major Service Class field, should be set to 0. http://www.oemblue.com/ info@oemblue.com 25 Chongqing Jinou Science &Technology Development Co., Ltd. Any reserved but otherwise unassigned bits, such as in the Major Service Class field, should be set Figure 1.2: The Class of Device/Service field (first format type).

12.4 THE MINOR DEVICE CLASS FIELD The 'Minor Device Class field' (bits 7 to 2 in the CoD), are to be interpreted only in the context of the Major Device Class (but independent of the Service Class field). Thus the meaning of the bits may change, depending on the value of the 'Major Device Class field'. When the Minor Device Class field indicates a device class, then the primary device class should be reported, e.g. a cellular phone that can also work as a cordless handset should use 'Cellular' in the minor device class field. 12.5 MINOR DEVICE CLASS FIELD - COMPUTER MAJOR CLASS http://www.oemblue.com/ info@oemblue.com 26 Chongqing Jinou Science &Technology Development Co., Ltd .
