The Basics
The connection status line of the eb505 module can be monitored to determine if there is an
active connection. Additionally, whenever a connection is present, the Connection Status
LED on the eb505 module will be on.
Resetting the eb505 to the Factory Default Settings
There are two different mechanisms to reset the eb505 module to the factory default settings.
Either by shorting the STATUS and MODE pins (pin 8 and pin 9) and then applying power to
the eb505 module, or by issuing the reset command to the eb505; see the command set
reference at the back of this manual for the syntax of the reset command.
Switching between Data Mode and Command Mode
When a Connection command is issued, the eb505 attempts to establish a connection to the
device with the address specified in the command. Once a connection is established, the
eb505 switches into data mode. At this point all data sent to the eb505 is transmitted to the
remote Bluetooth device over the wireless link. It is possible to switch from data mode to
command mode, issue commands, and then return to data mode, while maintaining a
connection. The eb505 allows you to switch between data mode and command mode by
issuing the Switch to Command Mode and Return to Data Mode commands or by driving the
MODE control I/O line (P6) of the eb505 module.
