Bluetooth Low Energy (BLE) technology is a low-cost, short-range, interoperable, robust wireless technology that operates in the unlicensed 2.4GHz ISM radio frequency band. The BLE standard is a bluetooth low energy product protocol set for small data block and low speed transmission, and various BLE products require that data frames are 20 bytes and frame intervals are greater than 7.5 ms.
