Disconnected! Specified native messaging host not found.

johnmastri commented 6 years ago

Followed the instructions, the console reads that the polyfill is loaded. When I check out the background page it says:

Disconnected! Specified native messaging host not found.

Please check the suggestions in this page regarding the "Specified native messaging host not found" error troubleshooting

For me it was caused by unpacking the BLEServer in the wrong directory. After that it connected with the server just fine. Sadly still doesn't show any devices though :(

I have the same problem. I have unpacked in the right folder and added the unpacked extension correctly afaik. BLEServer starts OK if run manually.

The polyfill is now deprecated - please use Chrome Canary with native Web Bluetooth instead.
