        hello my local name is:
                Puck.js 431b
        can I interest you in any of the following advertised services:
                ["6e400001b5a3f393e0a9e50e24dcca9e"]

https://github.com/sandeepmistry/node-bluetooth-hci-socket/pull/54

I used an nRF52-DK and the following but Windows 10 and chrome does not give a requester with the possibility to pair with the device
https://developer.mbed.org/teams/Bluetooth-Low-Energy/code/BLE_BatteryLevel/
https://googlechrome.github.io/samples/web-bluetooth/battery-level.html

ie a reference for if Windows 10 and Chrome and chrome://flags/#enable-experimental-web-­platform-features does not give a promising result.

It is hoped for a "Owen you did it wrong: I got it to work" and life goes forward, or else another wait for the Windows Chrome BoT (Bluetooth of Things)

Chrome for windows has web ble http://forum.espruino.com/conversations/299715/

Except, it doesn't seem to work, so I need a reference machine.
Virtual Box Ubuntu. Ensure that the host Windows 10 is NOT using bluetooth, Devices->uninstall driver for bluetooth device and delete files.

Then make sure that Virtual Box has Devices->USB->enable access to bluetooth adapter

However, nRF needs a certain type of adapter on all platforms it seems, not only windows.
So only supported on iPhone and Android as low energy and then it will work

funny, after checking last night and working on "something else" this morning...
Windows 10 Chrome is ready to go for bluetooth.

I play around for a while

chrome://flags/#enable-experimental-web-platform-features

Edit:
No sucess as yet with Web IDE https://www.espruino.com/ide/ no ports found

https://googlechrome.github.io/samples/web-bluetooth/ to check status of my Windows 10 chrome installation

Edit
https://googlechrome.github.io/samples/web-bluetooth/get-characteristics.html?service=device_information may be a "good test" puck.js doesn't show up in the pair list that Chrome presents in a requester
Even as DfuTarg, the puck.js does not appear, although in the ordinary windows show bluetooth, it apears as DfuTarg

Edit:
Double checked my puck.js with local installation of Web IDE and still working there when paired in Windows 10 OS

Breadcrumbs
https://github.com/NordicSemiconductor/secure-dfu-web-bluetooth with Espruino as a package.json keyword leads to a

A google on bluetooth-hci-socket gives a https://github.com/sandeepmistry/node-bluetooth-hci-socket

And a WIP which does not need any comments: I just edit this post to document for myself where the trail lead on Windows 10

Edit
The bluetooth in my device is supported:

Intel Wireless Bluetooth 7265	0x8087	0x0a2a

Edit:
zadig did it's work: bluetooth not available to Windows 10, and hoping available for the node of things

Edit:
Don't skip steps, go thru the doc and examples to make sure the base of DFU works when there, even if unnessary (DFU could work) time well spent

This is probably bad and I have to find a way to update the puck.js (where I started)

C:\source\repos\github\sandeepmistry\noble>node examples\advertisement-discovery.js
(no reply with battery off, button, battery on, green, release button, red)

I can confirm https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF-Connect-for-desktop :

• on windows, the nRF connect is an electron app, asar package
  
• on ubuntu/linux, the nRF connect is an electron app, luckly not asar: pack out and cherry pick js
  
• on OS X, I have not enough money for an apple :)
  
  

It seems the techy aspects of bluetooth with browser is Wait for Chrome but does that give the techy "serialized softdevice commands" with two outcomes:

1. puck.js can only be updated by an android/iPhone app that is not within Espruino control (no windows possible)
   
2. something may work in windows os: but don't hold yr breath timeframes and possibilities are unknown
   
   

Roll on Windows Desktop on Canonical Ubuntu: Xenix returns, with possible internal MS project name "Phoenix": but this is outside of the problem at hand.

Edit: package.json

"author": "Nordic Semiconductor ASA",
  "license": "Proprietary",

Edit:
A lot of code on Nordics github and unknown if "what is needed" is there.

Edit:
DFU seems to be https://github.com/NordicSemiconductor/secure-dfu-web-bluetooth
with a keyword Esruino in the package.json

And that it looks like the nRF Connect is a node product with an nRF core js

Yep: that was what I was thinking (also thinking of comments concerning uses of a nRF52X PCB :) from Espurino)

nRF Connect v1.1: no support for Windows 10 without a dongle
so looks like I have to find an android or iThingy in the cupboard: no problem

Hi,

Yes, nRF Connect v1.1 does support connection to BLE devices on
Windows 10, but it does require a nRF51/52 DK/dongle for
communication. Built-in BLE HW will not work as nRF Connect relies on
serialized softdevice commands and not HCI.

Look at the documentation in our inforcenter.

Best Regards,

Martin

Edit:
Probably something like this https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v12.0.0%2Flib_serialization.html

I have spent all day holding the top green board (mostly cos I have problems) but the size of a shield seems right
It is a bit bigger than the ORIGINAL ESPRUINO 54mm x 41mm (2.2in x 1.6in - half business card)

If I am write in Gordon wants the PCB as the same size as a shield with arduino pinouts

And if the area that is not with connector pins is a prototype area, I can allways break it of to make it square for a cubebit.js :)

nRF Connect v1.1 is available for windows but seems not to support bluetooth
https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF-Connect-for-desktop (anyone can download)
http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.tools%2Fdita%2Ftools%2FnRF_Connect%2FnRF_Connect_intro.html&cp=4_2
It is not possible to click "Start Scan" on my machine :(

I have made a case at nordicsemi
https://www.nordicsemi.com/index.php/eng/supportcase/view/34266

As a newbie, I presumed the GUI would update the device, clearer indication that the puck.js is not flasher-able: so very easy as the receiver of a puck.js just to look thru the GUI and think "great, flasher" (until one reads what is clearly written)

Better yet, use the info from "Request board details on connect" and allow for specific menu/dialogs in question with Flasher. (I will remember to make an issue of this)

• nRF Connect v1.1 for windows does not allow me to use "Start Scan"
  
• the puck.js apears as DfuTarg on Windows when put into the correct mode.
  
  

I try and do forum scans at nordic/google.

my case at nordicsemi
https://www.nordicsemi.com/index.php/eng/supportcase/view/34266

OK: you are going to love this ...
I only have a Windows mobile and a Windows PC.
nRF Connect v1.1 for Windows needs to be googled more: doesn't seem to have bluetooth, just usb

I get back on this one.

Or RTFM and find it is not via GUI :)
And find that "FIRMWARE UPDATES" has no info for windows (I create PR if wished).

"FIRMWARE UPDATES" could do with a quick link instead of reading down the page.

I use the already installed sw for windows and give it a go.

No update: as supplied to ensure I know what gets supplied to my friends if they order one :)
I update it via the GUI.

The code "works" ie it give me some nice LED's
The problem is, it stops working after a time.

// our main function
function puckLeds(){
  let leds= 0;
  let timerId = null;

  digitalWrite([LED3,LED2,LED1], leds);

  // watch for the Big Red Button
  setWatch(function() {
    if ( timerId !== null){
      clearTimeout(timerId);
    } 
    leds = (leds + 1)%7;
    digitalWrite([LED3,LED2,LED1], leds);
    timerId = setTimeout(function () {
    digitalWrite([LED3,LED2,LED1], 0);
    }, 10000);
  }, BTN, {edge:"falling", debounce:100, repeat:true}); 
}

// ensure that the code is available after reload or whatever
E.on('init', function() {
  console.log("hello");
  puckLeds();
});

save();

Edit after input below.
Placement of pulldown did not seem to work
pinMode(BTN,"input_pulldown");

function puckLeds(){
  let leds= 0;
  let timerId = null;

  digitalWrite([LED3,LED2,LED1], leds);

  setWatch(function() {
    // pinMode(BTN,"input_pulldown");
    if ( timerId !== null){
      clearTimeout(timerId);
    } 
    leds = (leds + 1)%7;
    digitalWrite([LED3,LED2,LED1], leds);
    timerId = setTimeout(function () {
    digitalWrite([LED3,LED2,LED1], 0);
    }, 10000);
  }, BTN, {edge:"falling", debounce:100, repeat:true}); 
  pinMode(BTN,"input_pulldown");
}

E.on('init', function() {
  console.log("hello");
  puckLeds();
});

save();

yes: the need is support Espruino.

I looked at the nRF52-DK: it is not allowed to really operate as a "consumer product".
So there is a markup for the value of being a "consumer product" for an Espruino product.

Arduino footprint

Yep: a pcb with full footprint with some thought to allow for a reduced pcb by reuse of a well thought out placement of components in relation to the risers on the board.
Any cubebit.js ideas can buy (some of) the stuff from espruino and tailer to own wishes.
The pic is posted before somewhere, but shows that when one has something in the hand to look at, one can better feel what is right.

I make a cardboard mock up for myself of the size of a cubebit.js and maybe makes some schematic/pcb with the only intension being to see if things look right.

Edit:
Of course, the pdb should give value in comparison to the nRF52-dk which has a known price with pros/cons in order to achieve "bottom dollar" for espruino

Arduino footprint has many merits : I am evaluating on the nRF52-DK.
However, it could be "nice" for a tight PCB with the io bought out into an easy expansion.
It could be nice to have a smaller Arduino io footprint if possible: the shield is quite big and a tight PCB is definable as small if this is what one wants.
I have to look thru the different versions of a standard Arduino footprint to see if there is enough on a smaller footprint ie tighter PCB

Honestly I'd like to keep the PCB as simple as possible -

I agree, a PCB that just works.
But can a PCB just work and allow for something else with a layered design of building blocks.

ie whatever Gordon is comfortable is the best, and whatever happens can happen if more comfortable with whatever is created.

node.js on windows is not painful : one just has to do it correctly :)

nw.js was under my radar and I have to do a "catch up" in the area: I think that Gordon is usually right, so my "catch up" has to hurry up.

electron is no bed of roses: I take Gordons comments very seriously.

Background information:
All the kids in the local council are getting chrome books, the same devices they will use when I do volunteer teaching so I need "problem free" usage: I take Gordons comments very seriously.

In general, I focus on Windows problem free usage (teachers) and will be doing chromebook (pupils) analysis so the kids can play and learn with teachers that can also follow what they are doing.
