    Smart Machine Smart Decision 1. Bluetooth Function 1.1. Bluetooth Introduction Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating prsonal area networks (PANs) with high levels of security.Bluetooth was standardized as IEEE 802.15.1 1.2.
  • Page 7 Smart Machine Smart Decision When the module as a Bluetooth headset role, we provide a set of AT commands to control the remote smart phones, such as phone calls, turn on or hang up calls and so on. By default, the module operates in power-saving mode, which means that the module can be simultaneously connected to a Bluetooth device.
