We have deployed Sinch into our app and all is working good except for a specific headset under a specific OS:
This is a USB headset which connects through a wireless USB dongle
It works fine with our Mac and Windows 10 computers
It connects correctly to our Windows 7 computers and we can hear audio (for example by watching a youtube video) and can record using its microphone
If we use it in our app to make a call, we can hear the ringing sound but then once the call is started neither the speaker nor the microphone will work. I do not see any Sinch errors or warnings in the console. This is running in Chrome
So, my question is: is there any debugging tool that we could use to try to find out why these headsets do not work during a Sinch call ?

I'm a student currently working with a Matrice 100 for a project. I know that currently you can stream to YouTube/Facebook from the mobile app, but is there any way to get the stream directly to computer? I noticed that there was a mini hdmi port on the controller, could you plug a cable into that and a computer to access the stream?
I'd leave this as a comment instead of an answer but I don't have enough reputation.
Do you have an HDMI cable on hand? You could try plugging one end into the hand controller and the other into a laptop.
Also, DJI has a ground control application for the PC (although I don't think they are continuing support for it) that can be used with a bluetooth radio to communicate with and receive video from the aircraft. The application is free to download from the DJI website.
I am trying to connect a Bluetooth Low Energy enabled MIDI hardware to wirelessly send data to a Windows PC and get it to detect as a MIDI device in Windows. Currently, the device is able to pair with my Windows 10 laptop and I am able to read the incoming data off of it.
The same hardware is configured and working fine as a wireless MIDI device on Mac and iOS devices(which natively supports MIDI over Bluetooth). I am trying to get this feature implemented on Windows(which doesn't support MIDI over Bluetooth, although it was promised in Windows 10).
The device, when is paired, is showing up in the 'Bluetooth devices' section in device manager, I am trying to make this device showing up as a MIDI device in 'Sound, video and game controllers' section.
Any help/resources somebody can provide to help me crack this problem is highly appreciated.
Following is my current thought process to implement this.
Pair the device and read the data off of it. (Already implemented)
Create a virtual MIDI port. (Don't know how to implement this, I am currently checking out rtpMIDI)
Send the MIDI data which was read from the BLE device to the virtual MIDI port. (Still don't know how to implement this)
Any suggestions/comments on the above thought process as I am absolutely new to Windows Driver Development.
I'm manufacturing a device that connects to my computer using Bluetooth and then a desktop Java app uses the Bluetooth connection to send serial data to the device which is then displayed.
When I try to connect my device to windows 7 it successfully finds and pairs with it creating a Bluetooth link on a COM port. This link can then be used by a serial prompt (used for testing) or my Java application. It works initially however soon after windows drops the connection and the only way to reconnect is to delete the device within devices and printers and then reconnect.
This seems to be a known problem with windows bluetooth so I decieded to use a third party Bluetooth application. I downloaded and tried Toshiba's Bluetooth Stack and it was able to add a Bluetooth device and keep a stable connection which works great however this only works for Toshiba computers without getting a cracked version.
This device is commercial and can't be sold with cracked versions of software. Has anybody experienced the same problems or not in other operating systems and has any solutions of advice as that would be a tremendous help.
This is not a good idea/method to use the COM ports generated by Windows, it's not working fine and not reliable in any scenario ; you should use Bluetooth Sockets instead.
Using Toshiba or Widcomm or BleuSoleil won't help: under Win7, all dongles are now trying to use the Microsoft Stack, not their own implementation.
I want to capture distances from sensors, using an Arduino and a Windows Phone device. How can I do that?
The Windows Phone 7 SDK does not give access to the USB port or Bluetooth on the phone, so you can't use that. So I think the best way (and probably only way on Windows Phone 7) would be to communcate over Internet or local network with the Arduino acting as a server which the Windows Phone 7 app connects too.
Here are some examples of an Arduino web server and TCP server.
For the Windows Phone client I would check out either WebClient or sockets.
Windows Phone 8 SDK:
Consider establishing an App to Device communication through Bluetooth API which became available for developers in the release. Bluetooth App to Device application sample, available on MSDN, is the way to go.
There is another option in Windows Phone 8, using Proximity (a set of classes which works with NFC), which is more applicable for a short range communication.
As for Arduino, there is certainly a Bluetooth module.
Windows Phone 7 SDK:
No way to establish a peer-to-peer communication with a third party device. A workaround would be to connect them through a network, as was proposed by Johan.
I have actually made a Windows Phone 8 App that connects to an Arduino using the Sparkfun Bluetooth Silver Modem. Issues is, even after I get them connected, I can't get either the Arduino to receive the input OR I can't get the WP8 App to successfully send to the Arduino...
My GitHub for the project is: https://github.com/lanceseidman/Arduino-Bluetooth-WinPhone8
Hoping everyone can try and help on the project.
My Breadboard photos will be up soon and my Arduino Code.
Whenever I disconnect my Windows Phone from PC (connected through USB) and if my application is running, my application hangs for sometime and then application crashes.
Does anyone experienced same behavior? I guess switching for PC connection to Wi-Fi/GPRS is causing the issue.
the windows Phone Requires that you Safely Remove hardware first, after a few times when i started Development on the windows phone i did the same and Ended up getting a new Phone. So plainly put, try to Safely Remove and Make sure it is installing the app to the Device.
Meaning if you Remove the phone, the App is still able to be ran just like a normal downloaded App form the Market place.
if you want more in depth information, i would suggest Reading the WP7 Everything Programming ebook lol
its filled with good information, and Definitely Helped me along my road to Love DEV for WP7.
As gamernb says, if you disconnect the USB from a properly tethered Windows Phone (i.e. connected to Zune, or using the WPConnect utility), the phone's network connection will be reset and your app's connections will be terminated. The phone will then start trying to connect using WiFi or cellular data (if they are on), but this can take quite a while.
You will have to handle this network disconnection in your app - I've found that pulling the USB cable in this way is a good ad-hoc test for WP7 apps: do an action which you know will use the network connection. Then watch if the app crashes, or handles this gracefully.
Actually you aren't guaranteed to always use the PC data connection: if you make sure that the computer has no data connection (i.e. pull the Ethernet cable, turn off WiFi etc ), the WP7 app can then use cellular data or WiFi on the phone instead.
Alas-
you could set perimeters in your application to Check what the connection type is, then Make changes accordingly.
You May have a slight freeze, but that's better then a crash....mainly when the phone switches from PC to WWAN, their would be a slight Pause.
use the Reachability Class and NSLog to Figure out whats going on exactly.
I really hope that helps!
