In the industrial sector, the possibility to transmit data wireless can make the installation of many a device simpler. The Bluetooth technology, in particular, is a standard that allows for the connection of a device to a computer within a range of several meters using compact circuits with low power requirements. Sinai Srl used this technology on devices that need to communicate with a computer, actually replacing the RS232 serial port and also the more modern USB. On PC side many off-the-shelf Bluetooth-USB converters exist but their variety of drivers often makes using them in the industrial field difficult, also representing an issue when it comes to reliability. To solve this problem, Sinai developed a BT-USB converter that provides a serial "Virtual Com Port" using Bluetooth technology.

Using Sinai's Bluetooth-USB converter and installing the included software, you can have at your disposal a serial port that communicates with the device in a completely transparent fashion. Using the "AT" commands or via the provided software, you can search for BT devices in the area and select which one you want to connect with. The converter is powered by the PC's USB port and features a LED that shows wether the device has been recognised by the operative system.
