Introduction
www.rovingnetworks.com
This document contains the software command set and advanced configuration settings for Roving Networks
Bluetooth devices. The document covers FireFly and BluePort serial adapters, all Bluetooth modules, and the
FirePlug USB dongle. Commands and settings that are specific to a single product or product family will be
identified as such in the document.
The reader should have a working knowledge of Bluetooth operation and communications. To program the
Roving Networks devices you will need a Bluetooth enabled PC (either built-in or using a USB Bluetooth
dongle). Only one device may be programmed at a time. Once programmed and configured device settings
remain (independent of power down) until they are explicitly changed or the factory defaults are restored.
Prior to getting started, power on the device and pair it with your PC. Roving Networks Bluetooth devices
can be programmed over the Bluetooth link or through the serial interface. To program the device you will
need to connect to the device by opening the COM port assigned to the Roving Network device through
either the Bluetooth or serial port interface.
Roving Networks Bluetooth devices are programmed with a simple ASCI command language which is
similar to the industry standard Hayes AT protocol. Set commands configure the module and get commands
echo the current configuration. Configuration settings modified with the set command do not take effect until
after the module has been rebooted, even though the get command may show otherwise.
Making a
By default the Roving Networks device shows up under the Bluetooth Devices directory as Serial Port Profile
(SPP) Service “FireFly-ABCD”, where “FireFly” is the type of Roving Networks device and “ABCD” is the
last four nibbles of the Bluetoot MAC address. The local device name can be changed. You will need to pair
with the device by double clicking on the device name and following the menu. The firmware automatically
stores up to 8 pairings from remote hosts in a first in, first out fashion.
If the remote Bluetooth device does not require authentication, a connection can occur without the pairing
process. However the Bluetooth specification requires that if either device involved in the pairing process
requires authentication, the other device must participate to ensure a secure link. The default mode of Roving
modules is an OPEN mode, such that the module does NOT require authentication. However most PC’s will
require authentication.
The pass key is a string of alpha or numeric chars, 1 to 16 chars in length. During the initial pairing process,
this code is entered on both sides of the Bluetooth connection, and must match to complete the pairing. This
passkey is used to create a secure link-key, which is then stored on both devices. Upon subsequent
connection attempts, the link-keys are compared and must match before the connection can continue. The
default Passkey is “1234”.
To connect to FireFly, browse for services, you should see: “SPP” profile with a virtual COM port. Open this
virtual COM port to create a Bluetooth connection. Once connected, the device will be in data mode
allowing data to flow in both directions as if the serial port were locally attached to the PC. The device must
be in command mode for configuration and programming. To enter command mode type “$$$” (three
