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=addr”command;
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.
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:
