    Hi,
    I am a complete electronics beginner but I would like to build the Dexdrip box to help monitor my diabetes.
    It is described here:
    https://github.com/StephenBlackWasAlreadyTaken/xDrip/blob/gh-pages/hardware_setup.md

    The problem I have is with the bluetooth module:
    HM-10 CC2540 4.0 BLE bluetooth to uart transceiver

    a) Most seem to be CC2541 versions which doesn't work apparently.
    b) it doesn't have any connectors as far as I can see - a problem for me

    The version on this page looks as though it has:
    http://circles-of-blue.winchcombe.o...-guide-to-building-a-dexdrip-wearenotwaiting/

    My question is does anyone know where I can get the one with the connectors or perhaps an alternative which should work?
    Thank you.

    Welcome to electronicspoint.

    So you'll have to get hold of a CC2540 module.
    Alternatively find out what the "apparent" malfunction is and correct it e.g. in software.

    As shown in the image (first link you gave) you solder wires directly to the contacts of the module.
    Alternatively you can solder pins into the connector holes. These are sold as "male pin headers" (e.g. like these) and are available from most electronics suppliers.

    Harald,
    Thank you for your help.
    I have now been told of firmware to update the CC2541 module.
