data mode, meaning it maintains an
active connection and can
receive/send data via the Bluetooth
port. (An example would be a user
creating a serial port using Bluetooth
management software on his laptop
and then using StarUtil 3000 to
connect to the receiver via that serial
port.) In this mode, the module has an
active data connection with a
connected device; it does not receive
commands because commands would
be interpreted as data that need to be
passed to the connected device.

The only way to return Bluetooth to
command mode once it is in data mode
is to issue a [BTSET]DISCONNECT
command, but keep in mind that issuing
this command drops any active
connection.

When the Bluetooth module is i
n “data
mode,” the keywords are
ON/OFF/DISCONNECT. The remaining
keywords return NAK -
“BT module in
data mode
”.

Turning on Bluetooth is associated with
a software reset of the Bluetooth
firmware, so the system returns the
same output as when the RESET
command is issued (see details on the
use of the [RESET] command in the
Sapphire Technical Reference Manual).
When Bluetooth is ON, another in-range
Bluetooth electronic device should be
able to detect the existence of the
system.
