Sony Camera Remote API SDK for Bluetooth

I am wondering if it's possible to use the Sony Sony Camera Remote API beta SDK / AddOn SDK / Smart Extension API to control action cameras functionality by my application side via BlueTooth (no Wi-Fi).
My goal is to write an extension which will mainly:
Mandatory: start and stop video saving on camera internal memory
Optional: , insert allarms, set video acquisition parameters, ecc.
Does anyone have:
the information if this SDK is the right choice to control this type of Sony device
if it's possible to reach my described goal with it or if there are any impossibilities
other related information or special requirements for controlling Sony cameras via bluetooth.
Thanks
Unfortunately you will only be able to use Wifi to control cameras with the camera remote API.

Does Sony RX10 camera support Sony SDK for remote control?

I have to developed a Windows application to remote control a camera from a pc for a photo booth. Basically this app will control zoom, exposure and shoot with a live view on the PC screen.
I'd like to use a Sony DSC RX10. Does this camera support Sony SDK ? If yes, are theses basic features supported by the SDK for the RX10 ?
Thanx !
The RX10 does support the API although the documentation do not mention this camera. I own a RX10 and developed a Windows Phone app for this camera as Sony only provides an Android and an iPhone version. The RX10 supports the same functions as e.g. the RX100M (see the list of supported devices and functions on https://developer.sony.com/develop/cameras/).
Exposure control is not supported by the API, zoom, shoot and live view are OK.

How to develop an application for the Sony DSC RX100-M3 camera

I have the RX100-M3 camera, and it seems that some applications can be developed for it.
As far as I understand, the CameraRemoteAPI SDK can be used to develop Android or iOS applications. So is there a way to develop applications for the Sony camera?
I would like to develop a feature to be able to:
set the timer (from 2s to 2min)
select the number of shots (from 1 to 2000)
select the time between shots.
There is an existing "intervalometer" application but it is very expensive.
Camera Remote API SDK allows one to remotely control the supported Sony cameras including RX100M3 from any other device, by sending HTTP commands to the camera. The application you create can run from any
platform Android, iOS , Windows, PC, etc. You will have to connect this device to the camera over WiFi.
To get more information, please download the SDK, which contains sample applications and API documentation.

How does a browser get GPS data from a computer?

HTML5 browser can retrive the gps position of a computer.
http://diveintohtml5.ep.io/geolocation.html
I would like to create an application that fakes a GPS device, but I couldn't read anywhere how the browser gets GPS data from the computer.
Chrome and Firefox:
GPS via gpsd if available (Linux only) 1, 2
system's Location API (Windows 7 only) 2
WiFi networks via Google Location Services 1
GPS coordinates are available only on mobile browsers. What you are discussing is geolocation generally. Your dekstop or laptop computer does not have GPS device. Locations are expressed in latitude and longitude.
For iOS use iOS emulator. You can set fake GPS coordinates. You can download it from developer.apple.com.
For Android use Android emulator. You can set fake GPS coordinates. Google Android SDK.
For other browsers / mobile vendors download the corresponding emuator.
Desktop browsers do not use GPS data. They use either IP based or WLAN based locationing. For desktop browsers just write your own test stub for navigator.geolocation.

How can a FlashLite Developer using Device Central emulate camera and file upload integration?

I am developing an application with Flash Lite designed to run on Nokia S60 5th edition phones using the Flash Lite API Bridge Interface. The application uses the API Bridge to access the phones camera and upload functionality to take a photo, display it to the user then upload it to a server. I am using Flash CS4 Professional and Device Central to develop and test the interface.
Are there any emulators that will run my flash lite app and simulate the camera? What are my options short of getting a phone and installing my app every time I want to test something new?
