BlueSense AD (Bluetooth)

Bluesense AD is a miniaturized module for the simple integration of Bluetooth communication in mobile sensoractuator networks.

Via AT commands, Bluetooth connections can be established analog to a classical modem, and digital and analog data can be transmitted. It has been optimized with regard to range and current consumption for medical and mobile applications. Thanks to the special antenna design, a 25 m range is possible under normal conditions. Even if there is shadowing by people in the vicinity, the transmission range is still 15 m. The current consumption is 6 mA when data is transmitted with active sniff mode (1.28 s interval), which is especially advantageous for battery-operated applications.

Bluesense AD can be operated either as a Bluetooth master or slave. In slave mode, it waits for a connection query from a master. After the connection has been successfully established, data is exchanged between the master and the slave. In master mode, by means of commands which are sent from a host controller via the UART to BlueSense, modules in the vicinity can be searched for and a connection established to them.

Bluesense AD has over two Bluetooth channels, over which analog or digital signals can be transmitted. For transmitting analog signals, a 12-bit A/D converter is integrated with 8 inputs. When one channel is used, the sampled values can be transmitted at up to 4000 Hz. The module can either be configured via Bluetooth or via the serial interface.

With Bluesense AD, you can upgrade your own application to become a wireless one, quickly and cost-effectively, without having to become familiar with the technical details of Bluetooth technology.
