HC-08 Bluetooth Module is a new generation of Bluetooth specification V4.0 BLE Bluetooth protocol based on the transmission module. It works in the 2.4GHz ISM band and uses GFSK modulation. The maximum transmission power is 4dBm and has -93dBm receiving sensitivity. It can achieve 80 meters of super long distance communication under open environment. The module uses the CC2540 chip, the configuration of the 256K Byte space. Using AT command, the user can change role, serial baud rate, equipment name and other parameters accordingly.
