Whether it is mitted through walls 100 meters is the barrier-free mission distance, and the mission distance through walls is relatively reduced 2. Whether the hardware device supports it Both Bluetooth mission and reception need to support the communication distance CLASS1 blue Otherwise, the power level be reduced to CLASS2, and the mission distance be around 10-35 meters.
