    Cool Re: What is the meaning of Bluetooth 4.0(LE)?



    Bluetooth 4.0(LE) is the low energy version of theBluetooth 4.0….it works on the same frequency as does the Bluetooth V2.1 …however the power consumed by it is much lower …this means that your battery drain will be very less if you keep your bluetooth on for longer times …the only drawback of the low energy version of bluetooth 4.0 is that the range it offers is very less , it being only 50 m which is only half of the range of Classic Bluetooth technology….however this range is quite greater than the popular NFC technology being used now-a –days and even the bluetooth V2.1, whose range is only 30 metres …another big advantage of the low energy Bluetooth technology is that the set up time that is , the time used to set up a bluetooth connection with other device is very small , being only of few ms

    However the Bluetooth LE is no new technology for smartphones …it had been included in the iphone 4s , that was launched last year !!

    hi friend,
    The meaning of Bluetooth 4.0(LE) is Bluetooth 4.0(Low Energy) .

    The special features of Bluetooth 4.0(LE) here are
    Range: ~ 150 meters open field
    Power consumption~0.01 to 0.5 (depending on use case)
    Max Current: ~<20 mA (max 15 mA to run on coin cell battery)
