Fitness tracker that supports espruino

Posted on
  • Hi everyone, I've been doing research for hours - We are trying to find a wristband / smartwatch /fitness tracker that you can write JavaScript on using Espruino. Do you have any recommendations?

    Our current fitness tracker uses nRF51 and is written in C.
    It has an accelerometer, Flash, EEPROM etc. etc.

    We would love to move to JavaScript but can't find a device that supports that or documentation that explains how to do so.

    Help will be greatly appreciated!


  • There was a port to the DO003 smartwatch (nRF51 16k) but realistically it wasn't usable for much due to the low amount of memory.

    There are some nRF52 smartwatches out there which Espruino could run on - some people have even reverse engineered some of them:Ā­ased-smart-watch-available/

    However it'll require quite a bit of work, and I don't believe the firmware update keys are available for the watches - which means that you'll have to take every watch you want to use apart and flash the firmware with an nRF52DK by hand.

    For quite a while I've wanted to get enough people interested that I could do that work myself and place a large order for watches with custom firmwares pre-programmed, but I'd have to get well over 1000 orders before they'd be interested in talking to me.
