Error when using Puck.eval in Web Bluetooth

Is it this bit that's not working?

<button onclick="Puck.write('\x10setTime(12345789);\\n')">Set The Time with x10</button>

I think it's to do with escaping in HTML, because you're in a string inside a string - note you have to do \\n for newline, not \n - maybe just doing \\x10 would fix it?

... and your puckCommand example wouldn't work, but for the other reason! Try changing \\n to \n in that one!
