The BL-819 RS232 Bluetooth adapters (DTE) are fully embedded, stand-alone Bluetooth solutions, which will Bluetooth enable any device with an RS232 port. The adapters do not require any additional Bluetooth software.

For many applications, a Bluetooth adapter used in combination with another Bluetooth product essentially replaces the serial cable, 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 connection uses Bluetooth security to ensure that sensitive data is not “sniffed” by any unauthorized source, although this feature can be turned off.

The BL-819 is designed as a cable replacement product. It’s primary function is to offer “point-to-point” Bluetooth capabilities to devices which otherwise do not have the capacity for such behavior. 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 at baud rates between 244 and 1.3Mbaud in steps of 244, with none, odd, or even parity, and with 1 or 2 stop bits. Its default factory settings are 115,200 baud, no parity, 8 data bits and 1 stop bit and Hardware or No Handshaking. A convenient reset button can be used to restore various functions of the device including a restore of last saved settings.
