connectBlue releases a Bluetooth based I²C (Inter-Integrated Circuit) OEM adapter which enables a cost-efficient and easy-to-use wireless solution when connecting devices such as displays, sensors and signal converters.
The new Bluetooth I²C Bus Adapter from connectBlue enables an easy and cost efficient way for wireless connection of I²C-interface based devices like displays, sensors and signal converters.
I²C is a multi-master serial computer bus that is used to attach devices to, for instance, an embedded system. By connecting the new Bluetooth I²C Bus Adapter from connectBlue to the I²C bus, the customer does not have to connect the I²C master device directly to the I²C bus. Instead, the new adapter implements the master side of the I²C bus interface and via Bluetooth functionality makes it possible to wirelessly enable a number of slaves on an I²C bus. The “original” I²C master implements a simple I²C look-alike protocol based on the Bluetooth serial port profile (SPP). The master device can then access all I²C slaves available on the I²C bus over Bluetooth wireless technology.
With a few additions, the Bluetooth I²C Bus Adapter is configured using the same AT commands as the connectBlue standard Serial Port Adapters. Typically, the adapter is pre-configured using a toolbox or AT commands, and then mounted and used for reading and writing data to and from the slaves on the I²C bus. It is also possible to use the Bluetooth I²C Bus Adapter more dynamically and/or to re-configure it over air.
