This BT module can easily achieve serial wireless data transmission. Its operating frequency is among the most popular 2.4GHz ISM frequency band (i.e. Industrial, scientific and medical). It adopts BT 2.1+EDR standard. In BT 2.1, signal transmit time of different devices stands at a 0.5 seconds interval so that the workload of BT chip can be reduced substantially and more sleeping time can be saved for BT. This module is set with serial interface, which is easy-to-use and simplifying overall design/development cycle.
