Unfortunately no. Web browsers on Android and iOS do it support advertising using Web Bluetooth.

Accessing USB device using firefox

Is there any way to access an USB device through Firefox on a local computer?
More details: I have created a USB device using microchip 18F2250 that sends data of thermal and humidity sensors & able to receive data to control a robotic arm..
The device has been tested on a C#2010 program to access the USB device successfully..
Now I run a HTML/javascript web page as a local server (http://localhost:8000/..bla bla bla..) & I need to access the USB device from this firefox bowser..
Notes : cannot use Chrome and its plug in WebUSB, I'm restricted to Firefox only for some reasons.
Any help??

sphero sprk+ isn't discoverable in macbook pro bluetooth

I'm trying to connect to Sphero Sprk+ device with gobot.io, like this example: https://gobot.io/documentation/platforms/sprkplus/
The code cannot connect to the device, so I checked in the visible bluetooth devices from Bluetooth Preferences in MacBook, and Sphero isn't listed there.
Sphero is visible from android devices, and is visible from the MacBook via Sphero EDU application, but not directly from the bluetooth console.
What do I miss?
Thanks
SPRK+ communicates via BLE (Bluetooth Low Energy). BLE comes with concept of 'profiles'. There are public (documented, well-known, standard) profiles, like SPP (serial port profile), A2DP (audio profile), etc. If the device supports these profiles, you can see it in system BT preferences.
However, SPRK+ (Sphero) features it's own private communication profile, not known to Apple nor Google.
That's why the EDU application can 'see' the device, but you cannot find it in BT preferences.

Detect whether a Bluetooth headset is connected to Apple Watch

I was recently trying to make a WatchKit App play a background sound effect from the Apple Watch’s speakers.
From what I experienced (correct me if I’m wrong!) this is not possible as I either need to connect a Bluetooth headset to use WKAudioFilePlayer or work with additional interface elements to play the sound (WKInterfaceMovie or presentMediaPlayerControllerWithURL:options:completion).
Now, instead, I would like to use WKAudioFilePlayer to have the audio played only if a Bluetooth headset is connected in order to avoid getting a „Pair a Bluetooth headset to listen to music“-alert every time no headset is available.
Is there any way to find out whether a Bluetooth Headset is connected, so I could make the audio playback conditional on that?
Still now there is no api available to check whether bluetooth headset is paired with apple watch or not

TV To Application Communication Protocol

I wish to develop a windows application that can steam video media to a TV. What protocol/interface allows two-way communication between a TV and a Computer?
I'm aware that HDMI is one-way communication (from the source to the TV) so the computers application cannot query what the current volume or current source is which is not useful. Is there a protocol that allows 2 way communication?
Also using HDMI is it possible to:
Change a TV's source? For example change to/from HDMI, AV1, AV2, etc.?
Change a TV's volume?
Or is it only possible to use HDMI to transmit video/audio data?
HDMI wont be able to control other aspects of tv like changing the vole or source. You can just stream via HDMI. If you wish to manage other things i would prefer you do it with chromecast or apple tv or roku. Chromecast is easy to start off.
