    the two other categories i'd put high on my projects are shields for relays (to control high voltage) and audio/dac to add music to my projects.

    this data logging shield would be very convenient: https://www.adafruit.com/product/1141

    i installed polyfill, and it allows the example web bluetooth pages to work online and locally. when i try to use espruino.com/ide it finds the bluetooth devices but crashes the bluetooth adapter when connecting to a puck. it says it can't get the board configuration, but it connects with no prompt available. again i can send code to the puck, and it loads, but an error follows saying that it can't get a prompt, and it's trying to recover.

    i haven't gotten to testing flow control yet, but since web bluetooth is working locally on windows with node express, then i'll use this opportunity to see what kind of dashboard i can get going. i'll continue more updates in a different thread.

    at least now i can program my hacking board remotely, and not need to be connected to the internet. now i can hack from a park just as easily as a coffee shop :)

    i have espruino.com/ide working on my rpi 3 b+ in chromium, but have not been able to get a local ide build working either.

    this is where it gets interesting, and i really just started experimenting with what works. out of the box these work with the uart friend and the wifi paired:

    1. Adafruit Bluefruit LE android app
    2. This example http://www.espruino.com/Puck.js+Web+Blue­tooth
    3. The same example running locally on an rpi 3 b+ with express https

    the web bluetooth ide sort of works from my rpi with this setup. it connects to the uart friend, but doesn't get a proper prompt setup. i can upload code from the right side, and use the repl, but it gives errors. interestingly, i can connect the web bluetooth ide to the uart, and the windows native ide directly to the wifi, and see console output on both sides :)

    the windows native ide sees the uart friend but fails to connect. it does connect to my puck just fine.

    the web bluetooth ide on windows behaves similarly to pucks and the uart friend, in that it will connect, but give no prompt. and then sometimes it just doesn't work at all on windows in chrome.

    ultimately i'd like to have a local web bluetooth ide working. it looks doable on my rpi 3 b+. i haven't tried it yet on windows. the web bluetooth examples seem to have problems loading the bluetooth adapter in chrome on windows as well.

    frustrating world for web bluetooth development at the moment.

    i will say using web bluetooth is a very convenient way to communicate with the esp wifi via the uart friend. my hacking board is completely wireless, and i can program the esp wifi via bluetooth.

    i don't think it would be hard to expand this to be a full IDE, though it's just my personal setup.

    yes, that link was the impetus for wanting to use NRF on the esp wifi. there's always a chink in the armor. i look forward to the new board.

    thx. will the new ble board be breadboard friendly? i currently have a large breadboard to hack around in coffee shops, with separate switchable power for the esp wifi and the le uart ble. i'm finding how unfriendly it is to secure ble devices, hence the switchable power for when not in use.
