In summary, the updated chipset coming from ST provides an innovative solution compliant with Bluetooth version 2.1 and 3.0. Communication with Apple iOS Bluetooth enabled devices is supported by these ST modules. The ST modules are BQB certified and are listed according to end product listing procedure on the SIG website, enabling the customer to apply for an EPL free of charge, allowing them to use the Bluetooth logo and Bluetooth marketing tools to support their product. STMicroelectronics’ Blue modules are fully integrated, tested, qualified, and RF certified, offering a complete Bluetooth modem function in a very compact size. This is a plug and play solution with easy integration, reliable design, no RF design issues, and Bluetooth implementation. The class 1 devices implement an onboard low power oscillator, the class 2 do not due to their small dimension; the LPO can be input to the class 2 module through a dedicated pin. This use of a low power mode and lower supply voltage ensures longer application battery life. Additional functions that make the module use easy and effective are Smartcable and remote mode control. Smartcable is a single command which launches the connection/paring subroutine for automatic connection between two predefined devices. Remote mode control enables GPIO and UART settings via Bluetooth link from a remote device.
