    Welcome Christine! Good to see the team is growing.

    Accelerometer would measure zero in every axis if there was no force acting for any axis. When you dont move you have the gravity force pulling you down and accelerometer measures that (if you are not floating in space). Try applying any acceleration (fast movements) in any axis and you will see that too. Here you have app for banglejs plotting accelerometer so will be easier to see that https://kristosb.github.io/WebBangle/
    If you want to sample fast, accelerometer will be better option than GPS. Accelerometers have different ranges. Some are better for measuring earths gravity (low range) other better for high forces like in an airbag. It depends whats your application.

    I never tried web bluetooth on a phone as client. I imagine the phone would have to make itself discoverable. As a hardware it should be capable. I am guessing you need to run some client side app or enable setting.

    Yes, you could test it with your phone first.
    @Gordon suggested laser sensors which would be my choice too.
    I am wondering what do you want to use the ranging for. From your initial project description I suspect you are trying to not only get rotation/inclination but also translation (moving in line)? If thats true I think this project might be more challenging. You get into stuff like SLAM and sensor fusion.

    Maybe not the most straight forward answer but you should be able to get it running based on those two posts.
    First is Web Bluetooth app connecting to a gyro device and visualising using three.js. Its not an espruino device but you should get the idea.

    Second is Web Bluetooth app connecting to espruino Bangle watch and visualising using tinydash.

    So using bits from both examples you should be able to do what you want. I want to make a version for the second demo using three.js but its not going to be any time soon.

    Hope that helps.

    Design is really nice. Similarities to apple watch. Not so many sensors. It would be nice to run espruino on it. I thought esp32 espruino build doesnt support the Bluetooth yet?

    That sounds good, thanks.

    Looks great! Its nice to play with physical buttons and knobs in the world of touchscreens and virtual UIs.

    Thanks Gordon. Global setting might just add complexity and cause problems somewhere else. I am fine with what I am doing now as solution. I thought it might be good idea to rise this topic so developers make the fonts more readable sizes.
    For the BTN2 disabling seems nice solution. I wont have to edit apps and having sequence to launch menu makes it child proof as well :)
