1. 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 has the discrimination of
principal and subordinate, which can be matched as one set. The principal and
subordinate equipment can establish connection, identify and memorize the opposite
equipments automatically when hardware circuit of Bluetooth RS232 adapter
connects correctly with electricity supply. The equipments of user can use RS232
Bluetooth adapter as the same as serial wires.
Bluetooth RS232 adapter can be used independently as well, excluding using by
match. When user’s equipment equipped with a RS232 Bluetooth adapter of one
subordinate equipment, other Bluetooth devices, such as Bluetooth PDA can search
out adapter of this RS232, and find out the services provided, then establish links and
communication with this adapter through these services as well. This module can still
be used as the same as the serial wires for the communications of users’ equipments.
RS232 Bluetooth adapter provides a safety identification function. When users
use safety identification, the equipments’ connects must be authenticated, and only the
authenticated equipment can realize communication. However this process could be
automatically finished among a matched Bluetooth adapter (acquiescence code:
1234).
In figure 1, users’ equipments between A and B connect by a serial wire; as
shown in Figure 2, users’ equipments between A and B connect by Bluetooth RS232
adapters. For equipments of users, these two types could be considered to be
connected with a serial wire. Figure 3 shows the connecting situation between
Bluetooth RS232 adapter and other Bluetooth equipment (shown here is the Bluetooth
PDA). Under such circumstances, for the user’s equipment, it is still the same as
indicated in Figure 1 and Figure 2_just like to be connected with a serial line..

4. Indicator light and press button
Link light is applied in RS232 Adapter to indicate the working state and the cmd
data switch is used to change the working mode (data mode or command mode).
LINK lights: If LINK light twinkles one time every five seconds, links with other
Bluetooth equipment should be finished; if it twinkles one time or even faster every
two seconds, it renders no links have been established. When there is no established
link, through LINK lights flashing speed, we can determine whether the equipment
has memorized address or not, that is to say, we can determine weather it is adaptable
for other Bluetooth equipment or not, if it twinkles fast (2 twinkles per second), it has
memorized address; if it twinkle slowly (1 twinkle per second), it means no memory
about addresses exists. For the principal equipment, it is normal that 2 twinkles per
seconds while consulting, 4 fast twinkles per second while matching, single twinkle
per second while linking, one twinkle per 5 seconds after connecting.
The LINK light extinguish while the RS232 is in the state of parameter stetting.
Cmd Data Switch: while moving Cmd Data Switch to the Cmd side, RS232
adapter indicator light is extinguished, the RS232 adapter is working in the state of
parameters setting. RS232 adapter stops working in the parameters’ setting state, you
can install only RS232 adapter parameters at this time. While moving Cmd Data to
the Data side, RS232 adapter quits the state of parameters setting, and begins to work
(search, match, link, transfer data, etc.) this time, but you can not install parameters of
the RS232 adapter. If users need to install parameters, please move Cmd Data Switch
to the Cmd side, if not, please keep the Cmd Data Data Switch on the Data side.
Hereunder attached the chart about indicator lights and button:
5. How to Set up Initial Parameter
RS232 adapter’s parameters are initially installed as subordinate equipment with
115,200 baud rate, and matching passwords 1234 (which should be searched and
4
matched by other Bluetooth equipment). It can be revised to suitable value according
to different situations.
6. LEG DEMONSTRATION
1) LEG Demonstration
As you can see from this picture, it is RS232 serial adapter, leg 1 is the power, leg
five is the stuff connecting earth. Usual voltage keeps 4.9V, and TTL signal keeps 5V.
When the module keeps the condition of being not connecting, leg 9 outputs lower
electricity. And it can reach to above 5V when it connects. Please let the leg 6 which
is a leg of cancel address connects low voltage usually. If you want to cancel address
and fit again, you should give it a high voltage.
2) Specification for Dongle
The module process edition number is 2.7. if you want to set the parameter,
please use the edition of 2.x set tool. And the specific using way you can find it in 2.x
edition using demonstration of set tool. You also should make the module connecting
to computer, and connect plug.
Module acquiescence parameter:
Usual voltage: 5v to 14v
input or output signal voltage: +/-5v
bond rate ： 38,400
Machine name RxBt01
Relationship: be subordinate to machine
Identity right: no
Corded or not: no
leg definition followed:
Pin1
Pin2 TxD
Pin3 RxD
Pin4 NC
Pin5 GND
5
Pin6
Pin7 CTS
Pin8 RTS
Pin9 VCC
Notes: Pin9 is plug (power)
Pin5 connects earth
When the module keeps the condition of being not connecting, pin1 outputs
lower electricity. Outputs high voltage after connects successfully.
Pin 6 is canceling address function.
7. Usage
If amendment of the parameters are needed, please move Cmd Data Switch to
Cmd side until the completion of parameter setting, and install related parameters via
the "AT command" or "parameter setting tool", such as parameters for principle/
subordinate equipment, baud rate, authentication and address binding. If the
communication is between two RS232 adapters, you should make an equipment the
principle one, and another one subordinate. Please move the Cmd Data to the Date
side after finished.
After starting the equipment up, if no memorized addresses are saved, search
nearby Bluetooth equipment first. If searching out, the principle equipment would
enter into matching state. If authenticating right, the principle equipment would
memorize (save) the address, and establish links with the equipment. If linking
success, LINK light twinkles one time every five seconds; if having memorized
addresses yet, the principle equipment connects directly with the memorized
equipment without inquiries and matching. The memorized address could be deleted
by using the AT command and parameters setting tool.
As for subordinate equipment, which wait for being connected and searched by
other equipment, its LINK light twinkles every five seconds, if connecting
successfully.
