BLE Devices do not appear in the connection dialog

[gguta]

This is what I get in the console. I don't know whether a connection between the non displayed devices and the exceptions.

Seems like there is a communication problem with the BLEServer.exe, the native process that does the BLE bridging. Can you please confirm whether you have Windows 10 Creators Update installed, as outlined here?

[gguta]

Yes, I do have "Version 1703 (OS Build 15063.483)"

Can you enable debug logging in the extension's background page and post the log here?

Closing for now due to inactivity

Hey there,

We're having the same issue. After enabling debug logging inn the extension's background page, this is what we see:

extensions::messaging:79 Uncaught (in promise) Error: Attempting to use a disconnected port object at PortImpl.postMessage (extensions::messaging:79:13) at Port.publicClassPrototype.(anonymous function) [as postMessage] (extensions::utils:149:26) at Promise (chrome-extension://opmhiclkbmjhmbkahdgghodkgiaoekpf/background.js:16:20) at Promise () at nativeRequest (chrome-extension://opmhiclkbmjhmbkahdgghodkgiaoekpf/background.js:7:12) at startScanning (chrome-extension://opmhiclkbmjhmbkahdgghodkgiaoekpf/background.js:106:9) at requestDevice (chrome-extension://opmhiclkbmjhmbkahdgghodkgiaoekpf/background.js:161:5) at port.onMessage.addListener (chrome-extension://opmhiclkbmjhmbkahdgghodkgiaoekpf/background.js:333:13) at EventImpl.dispatchToListener (extensions::event_bindings:380:22) at Event.publicClassPrototype.(anonymous function) [as dispatchToListener] (extensions::utils:149:26)

Okay we figured out the problem. The BLEServer download has to be extracted to the location noted, "C:\Program Files (x86)\Web Bluetooth Polyfill". If the location doesn't exist then it should be created.

I had extracted the BLEServer download to another folder, which was why I was seeing this issue.

Thanks for posting your findings!

[boogerlad]

I work with jteng7. I am getting the same error that he posted when I installed the polyfill identically on similar machines. Is there anything else I can show to help resolve the issue?

[boogerlad]

New finding: If this pops up when doubleclicking on BLEServer.exe

then chrome will fail silently. Uncheck to fix.

Also https://www.microsoft.com/en-us/download/details.aspx?id=48145 is needed

Awesome @boogerlad ! Can you send a pull request to the README file with this solution? I'm sure it can help others!
