Chrome Is Nearly Ready To Talk To Your Bluetooth Devices (engadget.com) 151

Posted by msmash from the connected-things dept.
Jon Fingas, writing for Engadget: Don't look now, but your web browser is about to become aware of the devices around you. After months of testing, Google has switched on broader experimental support in Chrome and Chrome OS for Web Bluetooth, which lets websites interact with your nearby Bluetooth gear. You could use a web interface to control your smart home devices, for instance, or send data directly from your heart rate monitor to a fitness coach. At the moment, trying Web Bluetooth requires the stars to align in just the right way. You'll need a pre-release version of Chrome 53, and you'll naturally want to find (or create) a website that uses the tech in the first place.

              Unless you've audited the code of the browser and compiled yourself it with a compiler whose code you also have audited you cannot know if a browser is doing bad things behind your back. That is true whether or not the source code is open source or closed. Open source does have its advantages but it just changes the attack surface rather than eliminating it.

                  I have bad news for you. All major browsers have been offering web sites access to any attached webcams and microphones for many years now. Of course they ask you if you want to allow access first, and you can set an "always disabled" flag, but the code is in there.

                  I find it quite amusing what Google has done. They build an OS on top of every other OS in the form of a browser, making the underlying system pretty much irrelevant. All apps run in the browser now - Google's office apps, their cloud file storage, video conferencing and soon health monitoring via Bluetooth sensors.

                  I still don't want it.

Even if you go to a site that you trust, there's *still* no guarantee that you're safe because they may serve something malicious by accident. This has happened more than enough times that this scenario should be front and center in everyone's minds.

              Are you familiar with FireFox's pop-ups "the website http:/// [http]{whatever}.com has requested access to your webcam/your microphone/your localisation/streaming your desktop/etc." ?

              Webapps in your browser can already get access to your microphone or stream a video of your desktop.
              But 99% of the regular pages don't need it.
              So, the default behaviour is that the few 1% webapps that need special access to some hardware need to first ask for it and a pop-up asks you if you grant access to it.

              In many ways the browser is actually a good platform for app, so perhaps we should be welcoming this. It's heavily sandboxed and partitioned, and the attack surface is much smaller than for an app running natively on an OS. "Apps", really web sites, don't require installation or updates. It even forces the apps to be somewhat open source, even if they do use a lot of obfuscation and service side processing.

              There are huge down-sides as well, but as a platform the browser isn't the worst one out there.

            Abstract answer to your abstract question many native applications can get by with much less total complexity than required simply to invoke "hello world" on a modern browser stack. What does the browser weigh in at? 10-20 MLOC? All of that on top of cost of OS provided facilities. I bet many applications people use come in way under that.

    I have been taking advantage of the BT (SPP/RFCOMM) operation in Chrome and ChromeOS for a white now on a variety of devices and for the most part it works quite well. My app is a Chrome App (Extension) in which the code is written in JavaScript.

    Unfortunately, when you have multiple ChromeOS systems (ie Chromebooks) connected to BT devices simultaneously, you experience some weirdness (previously paired devices not being found with a "undefined" error and requiring several connection attempts as well as connections failing after a few minutes). I'm working at figuring out what the problem is.

    The Chrome.Bluetoothsocket discover and connect APIs will find, pair and connect devices quite nicely on all Windows and Linux systems but not Macs. Macs require going into "System Preferences" and pairing your device beforehand. Linux requires something like Blueman to be installed and works reasonably well.

    This could provide some interesting functionality, but I suspect there will be problems with the first implementations along with the issues listed above. It will probably be solid in 2-3 releases (4 to 6 months) after multiple users have identified issues with it.

      • Sorry - I should have noted that if it's a Windows device, the BT pairing dialog boxes come up and unless the PIN is trivial (0000, 1111 or 1234) the user must enter the pin and in either case, the user must confirm that they want to connect the device.

        As noted, if it's a Mac, you must go under "System Preferences".

        If it's a ChromeOS device, there is no user confirmation.

        There is no user confirmation under Linux.

    Another day, another new web API that's impractical to test across a home or small office LAN, just like Service Workers before it.

    you'll naturally want to find (or create) a website that uses the tech in the first place.

    I have one machine on my home LAN that I want to use as a server, and another machine that I want to use as the client. But from Google's page about this new feature [google.com]:

    HTTPS Only

    Because this experimental API is a powerful new feature added to the Web, Google Chrome aims to make it available only to secure contexts. This means you’ll need to build with TLS in mind.

    It recommends running python -m SimpleHTTPServer on localhost. But that fails if the web server and web browser are running on separate machines, which might be the case if the machine that you are using as a web server to test your app, such as a Raspberry Pi board, is incapable of running Google Chrome or incapable of connecting to Bluetooth devices.

    I personally enjoy GitHub Pages for demo purposes.

    That's fine for demos that have reached the stage where they are ready for public consumption. I'm referring to the stage before that.

    To add HTTPS to your server you’ll need to get a TLS certificate and set it up. Be sure to check out the Security with HTTPS article for best practices there. For info, you can now get free TLS certificates with the new Certificate Authority Let’s Encrypt.

    Let's Encrypt issues certificates only for domains that have either A. publicly reachable dynamic DNS or B. a publicly reachable HTTP server. Neither of these is likely to apply to a machine on a home or small office LAN.

      Self-signed certificates are not difficult to generate and install in your browser.

        An internal CA solves the narrow "developer on a home LAN" issue because a web developer is presumably tech-savvy enough to generate a root certificate and install it on the machine running Chrome. Thank you for your answer.

        Am I allowed to ask a second question about other problems with an HTTPS-only policy that I foresee, related to a home server appliance intended for use by less tech-savvy users on a home LAN? Or would that be moving the goalposts?

      A related but different question:

      I plan to develop an application that runs on a PC and acts as an HTTPS server that other PCs on the same home LAN can access. It cannot be accessed from the Internet; connections from outside 10/8, 172.16/12, or 192.168/16 are refused to protect the privacy of the information that the application stores.

      I want to make a web application instead of a native application so that I don't have to spend five times as long remaking the application for five different operating syste

      For testing you can simply generate your own certificate and manually install it on your PC and server. You only need to buy one if you need it signed by someone in the chain of trust, but if it is just for testing on your own systems then you, as administrator, have the power to trust whatever certs you like.

  • Is this part of that whole cluster-fuck where my fridge automatically orders milk when I'm low?

    No

    Thanks

  • OK, "protected" is maybe not the right word. Microsoft is just not providing support for Bluetooth LE (GATT) prior to Windows 8. I'm assuming Chrome won't be providing their own BT stack.

  • This is dangerous business. Google needs to get this JUST right, or it will be a ridiculously easy-to-exploit attack vector.

    • This is dangerous business. Google needs to get this JUST right, or it will be a ridiculously easy-to-exploit attack vector.

      The problem is that "JUST right" is a state of limited duration. And all too often it's a VERY limited duration. As for Google getting it 'just right', even for 5 minutes - well, I suspect they really don't give a flying fuck, considering that they regard us all as mere experimental subjects anyway. We're all basically lab rats as far as Google is concerned.

  • Just let the damn browser be a browser, stop building O/S capabilities into Browsers, we don't need local storage, we don't need DRM we just want it to open and render web pages.

      Because developers want to deploy applications to users of Windows, macOS, X11/Linux, iOS, and Android. A native application works only on a single operating system unless separate native applications are made for each operating system. If accessing local storage, the camera, Bluetooth, or other features of your computing device requires a native operating system, then it'll likely end up being your preferred operating system that gets left out.

  • I'm not ready for Chrome to talk to my bluetooth devices. I mean, I cannot imagine how that's going to be misused.

  • My bluetooth-powered ad-blocker is almost complete.
