Command Mode vs. Data mode
Upon power up the device will be in data mode. To enter command mode, send the characters “$$$” through
the serial port or from the remote Bluetooth connection. The device will respond with “CMD”. To exit
command mode, send “---<cr>”. The device will respond with “END”.
While in command mode, the device will accept ASCII bytes as commands.
A quick check to see if you are in command mode is to type the “D” and “E” commands after entering
command mode. This will show the parameters, such as the Bluetooth Name, Class of Device and Serial Port
settings. To access configuration, the device must be in command mode by issuing “$$$”.
You must enter command mode with in the 60 second configuration window or the module will go into fast
data mode where all characters are ignored including the “$$$”. If the configuration timer expires while in
command mode the device will not go into fast data mode after exiting command mode.
You can not enter command mode from the remote Bluetooth connection if the device is in Master Mode.
Local Configuration (via serial port)
Use a normal RS-232 pass through cable from PC to send ASCII characters through the terminal to the
Roving Networks device. The serial port settings must match the Roving Networks serial port configuration.
By default these are set to:
Local configuration works at any time when the device does NOT have a Bluetooth connection, and also
works under certain conditions. If the device is in configuration mode and a connection occurs, the device
will exit configuration mode, and data will pass back and forth from the remote device.
Run your favorite terminal emulator, HyperTerminal or other program. Type “$$$” on your screen. You
should see “CMD” returned to you. This will verify that your cable and comm. settings are correct. Valid
commands will return an “AOK”, response, and invalid ones will return “ERR “. Commands that are not
recognized will return a “?”.
To exit command mode, type “---“<cr>. (three minus signs).
NOTE: You can enter command mode locally over the serial port at any time when not connected.
Once a connection is made, you can only enter command mode if the config timer has not expired.
To remain in configuration mode set the config timer to 255. Also, if the device is in Auto Master mode 3, you
will NOT be able to enter command mode when connected over Bluetooth.
