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 device’s 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 side’s Bluetooth
disconnect automatically, our serial adapter will not disconnect automatically and the
connection will always remain.
