This section describes how to quickly make your first Bluetooth
connection based on the following combinations of Bluetooth hardware:-
1. Two blu
2i
Modules.
2. One blu
2i
Module and a Bluetooth Enabled PC using TDK’s Go
Blue USB Adaptor or PC Card.
Note: The following examples assume that a PC is used to control the
blu
2i
Module using a Terminal Emulation application.
8.1.1 Two blu
2i
Modules
Assuming your PC has 2 serial ports (COM1 and COM2) or that you
have 2 PCs that each have one free serial port, attach a blu
2i
Module to
each COM port. Launch a terminal emulation for each COM port and
start off with comms parameters 9600,N,8,1.
Type AT<enter> and confirm that you see it echoed and then an OK
response. If you do not see this behavior, close the application and
restart with comms parameters 115200,N,8,1 and try again.
On the first terminal emulator application, enter the following
commands:-
ATI4
ATS0=1
AT+BTP
The response to ATI4 will be the modules Bluetooth address in the form
of a 12 digit hex number.
On the second terminal emulator app, enter the following command:-
ATD<bd_addr>
Where <bd_addr> is the 12 digit Bluetooth address you saw in response
to ATI4 above.
After a moment, you will see the response “CONNECT <bd_addr>” on
both terminal emulators. This confirms that you have a Bluetooth
connection between the two.
