Bluetooth has become a popular way of communicating with serial devices due to low cost, reliable communication, ease of use and because Bluetooth is readily available in most modern laptops and handheld devices; and in case Bluetooth is not available then it can easily be enabled by using a USB Bluetooth dongle. Bluetooth is ideal for short range communication for up to 100 meters (300 feet).

Setup Methods

This serial Bluetooth adapter will allow you to communicate with a RS232 serial device from any computer with Bluetooth enabled. You can create a link directly to the computer in which case the operating system's Bluetooth drivers will create a virtual COM port (in Windows 8.1, 8, 7 and Vista); or you can pair two of these serial Bluetooth adapters with each other in which case they work independent from the computer's Bluetooth drivers, in other words, if you use these adapters in pairs then your computer does not have to have Bluetooth capabilities; this is almost like a direct cable replacement.
Here are some simplified setup examples:

Parameter Management

The adapter's parameters can be configured over Bluetooth or through the serial RS232 interface. We highly recommend configuring this adapter through the serial port as configuring it over Bluetooth can be kind of tricky if you are not used to dealing with this type of adapter. If your computer does not have a serial port then you can connect the serial Bluetooth adapter to your computer by using a USB to serial adapter; we recommend the XS880 which is a good quality adapter at a reasonable price.

Compatibility and Uses

This serial to Bluetooth adapter is compatible with most standard RS232 devices such as serial printers, scales, process equipment, CNC machines, alarms and virtually any other kind of device or machinery with a standard RS232 port.
It can be used in most types of environments including laboratories, warehouses, offices, machine shops and most other commercial or industrial environments; however please notice that this adapter is not water or dust proof so necessary precautions must be taken if the adapter is used in such environments.

Each package contains one Bluetooth serial adapter which works as a full duplex transceiver, meaning it can both transmit and receive data. You will need two of these Bluetooth serial adapters to setup a communication link unless you already have a built-in or external Bluetooth dongle. Take a look at our detailed setup examples to see how this adapter can be setup.
