Introduction
1.1.
Preamble
Brainboxes’ RS-232 Bluetooth adapters are fully embedded, stand-alone Bluetooth solutions, which will Bluetooth enable any
device with an RS-232 port. These adapters do not require any additional Bluetooth software.
For many applications, a Bluetooth Adapter used in combination with another Bluetooth product (e.g. Brainboxes’ USB to
Serial adapter connected to a PC with Brainboxes’ Bluetooth Software Suite, or a second adapter) essentially replaces the
serial cable. This means freeing the device from the limits imposed by the cable specification and in many applications
removes the need for expensive cable installation and maintenance. The devices are designed to appear transparent to a
user’s applications that would otherwise be communicating via a COM port and over a cable, therefore no specific Bluetooth
programming is required. The connection uses Bluetooth security to ensure that sensitive data is not “sniffed” by any
unauthorised source, although this feature can be turned off.
The products described by this document are designed as cable replacement products. Their primary function is to offer
“point to point” Bluetooth capabilities to devices which otherwise do not have the capacity for such behaviour. This capability
is configured by a “set and forget” interface, which is not designed to cater for multiple device connection scenarios. At the
time of publication, the adapters are only capable of connecting to one other Bluetooth device at a time.
The Adapter is user configurable to baud rates between 1200 and 921,600 baud with none, odd, or even parity, and with 1 or
2 stop bits. The default factory settings are 115,200 baud, no parity, 8 data bits and 1 stop bit.
A convenient reset button can be used to restore various functions of the device including a restore of factory settings.
We trust that if you adhere to the following procedures you will enjoy many years of useful service from your Brainboxes
Bluetooth Adapter.
