PREPARATION FOR USE
The EGBT-046S is permanently configured as a
slave Bluetooth device. It works under the following
default configuration:
Baud Rate:
9600 bps
Data
:
8 bits
Stop Bits:
1 bit
Parity :
None
Handshake:
None
Passkey:
1234
Device Name: linvor
If the default configuration suits your application,
then you can use EGBT-046S immediately. Once
it is paired to a master Bluetooth device, its opera-
tion becomes transparent to the user. No user code
specific to the Bluetooth module is needed at all in
the user microcontroller program.
The EGBT-046S automatically sets itself up in
Command Mode when it is not remotely connected
Figure 4. A PC may be used to configure the EGBT-04. To connect to a PC COM port, a RS-232C to TTL converter
is needed. This figure shows a wiring example using e-Gizmo RS-232 to TTL converter kit.

(paired) to any other Bluetooth device. You can
change the Passkey, Device Name, and Baud Rate
while the EGBT-046S is in Command Mode by
entering a small subset of AT style commands. Any
changes made will be retained even after power is
removed from the EGBT-046S, hence device con-
figuration setup must not be repeated unless new
changes need to be made.
You can do configuration setup using the host con-
troller itself (the microcontroller in your own circuit),
or a PC running a terminal software using a serial
to TTL (or USB to Serial TTL) converter. See Figure
4 for connection details.
It is important to note that EGBT-046S does not
wait for any termination character for each AT com-
mand entry. Instead, it acts to whatever character
you entered after one second. Hence, if you are not
able to complete a command entry within a second,
it will be ignored. Because of this behavior, it may
be extremely difficult to do manual entry configura-
tion using Windows Hyperterminal software. Termi-
nal software that allows batch sending of multiple
characters must be used.
