Recently, the environment for using BLE on desktop PCs has been prepared. This time, we will talk about making Web Bluetooth available on Ubuntu 20.04.
environment
- Ubuntu 20.04 AMD64
- blueZ 5.53 --chrome version: 86.0.4240.111 (Official Build) (64-bit) --Chromium version: 86.0.4240.111 (Official Build) snap (64-bit)
Correspondence situation
「Implementation Status」 https://github.com/WebBluetoothCG/web-bluetooth/blob/master/implementation-status.md
according to,
「Linux is partially implemented and not supported. The chrome://flags/#enable-experimental-web-platform-features flag must be enabled.」
There is. Also,
「Linux: Requires Kernel 3.19+ and BlueZ 5.41+ installed. Read How to get Chrome Web Bluetooth working on Linux. Note that Bluetooth daemon needs to run with experimental interfaces if BlueZ version is lower than 5.43: sudo /usr/sbin/bluetoothd -E」
There was also. Previously, when I tried it on Ubuntu16.04, the version of BlueZ was low and it didn't work. Well, I wonder if it will work this time ...
Now, https://developer.mozilla.org/en-US/docs/Web/API/Web_Bluetooth_API According to it, firefox is not supported.
Setting work
Status check
Originally, when you try to pair, the following dialog will appear.
This site has been confirmed to appear on Google Chrome on Windows 10 and Android, but not on Google Chrome on Linux.

The following packages were installed automatically but are no longer needed:

It was already in. The version is also 5.53, so there seems to be no problem.
Google Chrome
next,
chrome://flags Open and #enable-experimental-web-platform-features To Enabled.
It was convenient to be able to access directly with the following URL.
chrome://flags/#enable-experimental-web-platform-features
With Google Chrome, you can now use Web Bluetooth by itself.
Chromium browser
I also tried it on Chromium. chrome://flags/#enable-experimental-web-platform-features Go to and enable it as above. After restarting the browser, I tried it and it was OK.
