Problems connecting to Windows 7 desktop

https://github.com/sandeepmistry/node-bluetooth-hci-socket#compatible-bluetooth-40-usb-adapters so BCM20702A0 is ok for nobel

Check the VID PID

BCM20702A0 Bluetooth 4.0	0x19ff	0x0239
BCM20702A0 Bluetooth 4.0	0x0489	0xe07a

Edit:

At the present time, I have no Windows 7 machine at hand: a lenovo with probable bcm in the celler but instead I looked at the following

For Windows earlier than 8.1

Since Windows versions earlier than 8.1 don't support Web Bluetooth in
the OS, noble (which the Espruino IDE uses) has to be able to access
the BLE adaptor directly - so you have to make sure the WinUSB driver
is loaded for it (as opposed to a manufacturer-specific driver).

Download Zadig and run it - it's just an executable Go to Options ->
List all Devices Choose your BLE adaptor (mine is CSR8510 A10) Make
sure WinUSB is set as the driver Now when you next run the Native Web
IDE and click 'connect' in the top left, you should see a list of
connectable BLE devices.

Well, in theory, my Windows 10 with zadig could operate like a pre-8.1: ie nobel.
(I have zadig installed and nobel from node gives no problems).

However, the Native Web IDE ("The Web IDE is available as a download for 64 bit Windows:") does not work with my Windows 10 / Zadig setup.

Is this a "good" test???
Well look at the error message at the top and think about the issue I posted at noble.

I think that the hci module needs a refresh

We have chrome.serial - not using 'serialport' module
'noble' module couldn't be loaded, no node.js Bluetooth Low Energy  Error: No compatible USB Bluetooth 4.0 device found!
Disable Web Bluetooth as we have Winnus instead
