    Hi all,
    I haven't yet a Neo board but I need some tech info.
    I'm working on beacons, in particular on Eddystone protocol and I created some devices using Raspberry Pi or PC and an usb bluetooth dongle. It's a very useful platform for development and research.
    I'd like to reduce the tx power to obtain a super-localized beacon (range of 1-1.5 m) but it seems impossible on CSR 4.0 dongles.
    I used the following command to set to 0 level
    sudo hciconfig hci0 inqtpl 0
    but the level is always 4.
    Can you try on Neo or give me any feedback?
    Thanks a lot

    The command succeeds, but how to verify if it works?

    To adjust the TX power level the command is:
    sudo hciconfig hci0 inqtpl 0
    to read the current level:
    sudo hciconfig hci0 inqtpl

    Thanks Andrea
