Description

blutronium

This is our new 2nd generation version 2 serial to Bluetooth Long Range adapter with an external antenna. It is replacing the older UCBT232EX adapter. This new version has an new processor for better stability and performance, Bluetooth version 2.1, more functions and is more user friendly. This version has several improvements:

Parameters can be configured over BLE Bluetooth using an iOS/Android app.

One of the most noticeable improvements is that this 2nd generation version 2 adapter's parameters can now be configured over BLE Bluetooth using an app on any iOS or Android phone or tablet. The app will connect to the adapter via BLE Bluetooth and the user can then easily select which parameter to configure.
Alternatively the adapter can be configured using AT commands using a standard terminal program such as Putty or Tera Term. However this rather old fashioned way of configuration is not very user friendly, especially because it requires a USB to serial adapter to be able to connect the adapter to a PC for the user to be able to search for the right AT command to set the correct parameter.

Supports more data bits and stop bits

While older serial Bluetooth adapter usually only supports 6 and 7 data bits and 1 or 2 stop bits, this new version 2 adapter supports 5,6,7 data bits and 1, 1.5 and 2 stop bits, meaning it will be compatible with even more types of serial devices.

Easier pairing with slave adapters

This new version 2 serial Bluetooth adapter has two new functions: the 'one' command and the 'auto' command. With the 'One' command the master adapter will automatically pair with only one slave adapter, even there are multiple adapters within the same range.
The 'auto' command will allow the master adapter to automatically pair with multiple slave adapters with the same pin code.

A Versatile Wireless Solution

Using a serial to Bluetooth adapter is a fast, easy and reliable way of connecting a serial device to a PC, or to link two serial devices with each other as a direct cable replacement.
The communication range is up to 300 feet line of sight when using Class 1 Bluetooth devices, and since Bluetooth inherently has secure 128bit encryption you get a very good and secure communication link.
It will work with most devices which has a standard serial RS232 port such as serial printers, building control, scales, office equipment, alarm and security devices, telescopes (tested with ASCOM drivers under Windows with Celestron and Meade telescopes), CNC's, most manufacturing machinery and many many more types of serial devices. This adapter will also work with most Cisco routers and switches (tested with Cisco Catalyst 3560).

You can communicate with this serial Bluetooth adapter using a PC with built-in Bluetooth or by using an external USB Bluetooth dongle. The advantage of using one of these methods is that you will need only one serial Bluetooth adapter to setup a communication link with a PC.
If you need a direct cable replacement which automatically links two serial devices together without using a PC then you can use two adapters linked together as a pair.

The adapter can be powered by the included USB cable, through screw terminals or through the DB9 connector.

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.
