Are you using the Chrome Web Browser on your Tablet, or some other browser? It may have be be Chrome to work.

Also, you don't need to have paired with the Espruino device - in fact it might potentially make it harder for the Web IDE to find the device.

Yes, I am using Chrome.

So, I unpaired, and then tried again and still getting no ports.

No navigator.bluetooth - Web Bluetooth not enabled doesn't sound promising. Could you go to:

https://googlechrome.github.io/samples/web-bluetooth/device-info.html

and see if that works?

Also try chrome://version in the address bar and see what version it gives you on the first line.

Posted at 2018-08-02 by Terrence7

Chrome Version 50.0

Ok, I enabled the following:

Type in chrome browser:
chrome://flags
Then enable:
Experimental Web Platform Features
and
Web Bluetooth

Now when I click the connect button, the IDE shows the "Select a Port" window.
When I click it, it does not find the puck. I have it in pairing mode, but no pairing.
Oh, and I turned Wi-Fi off (reading some past posts)

Ok, that's your problem - try upgrading Chrome.

Chrome is now on version 68 - version 50 is over 2 years old now and is from before Web Bluetooth support was added.

Ok, I have upgraded to Chrome 68, but when I try and connect it tells me "no compatible devices found"

I don't need to use Web Bluetooth, I just want to be able to program the Puck.

I have windows machines and an Android tablet (issues above). Any other ways I can program it with the IDE?

Hello @terrence7

Does this help?

http://www.espruino.com/Puck.js

Firmware Updates

via nRF Toolbox App (iOS & Android)

On your Bluetooth LE capable phone, install the nRF Toolbox app

Source code available to download for iOS , Android 4.3 or later and Windows Phone here.

"no compatible devices found"

Could you get a screenshot of the error? Could the Puck still be paired to either the Android or a Windows device? It can only be connected to one computer at once, so if it's connected to something already it won't show up to other devices for connecting.

Any other ways I can program it with the IDE?

The Native Web IDE should work on Windows: http://www.espruino.com/Web+IDE#as-a-native-application

Either Windows 10 PCs natively (after pairing), or any Windows PC with a standard $10 bluetooth dongle (see here) should work - surely one of your Windows machines will work like that?

You can also use EspruinoHub on a Raspberry Pi 3 or Pi Zero W - you can then connect to raspberrypi.local:1888/ide and can program Espruino through that

I have and without the availability of a smart phone, I believe I'm out of luck.

Firmware updates are now available via the Web IDE website espruino.com/ide if you have Web Bluetooth. However if you're on Windows and you don't have access to a Smartphone (or a friend that you can borrow one off for 10 mins) then yes, updating will be hard. However very soon Google should be producing a working Web Bluetooth for Windows 10, so that should all get solved.

As there aren't wires, need to communicate via Bluetooth

You can connect a $5 USB-TTL converter to program it if you want to: http://www.espruino.com/Puck.js#serial-console

I just saw your other post - try booting the Puck outside of Bootloader mode. The IDE is designed to connect to a normal Puck, not the bootloader itself.
