I am using the Sony SDK to develop a solution using the ILCE-QX1 camera. I need to keep the camera powered up at all times but sometimes the camera will power down if the network connection has a glitch. There is no way in the SDK that I have found to tell the camera to not power down. I am using the camera with the AC adapter so the camera always has good power.
I'd like to create a Windows Phone 8.1 app to connect to a TV and have basic controls (change channels, turn on/off).
I know It's hard to have an universal remote for every TV, but I'm just testing so It could work to a specific model/maker.
My first guess is to connect to a smart tv over wifi connection, but I can't find any site to describe how to do this or how do I start researching. I only got links to apps already made, but not on how to build it.
Anyone knows how this connection works?
Thanks!
i dont think this is really related to Windows phone specific. but here is what you can do:
find out what kind of API the TV has. it's probably some Rest or SOAP based webservice you can call. if there are existing apps (maybe for other platforms) you can use Fiddler to check the network traffic from these apps to the TV if you set your pc as "man in the middle" with fiddler.
as soon as you have what you need look into HttpClient examples on how to send these requests toward your TV.

I'm debugging some windows phone 8 location tracking application and I want to purchase gps-receiver and connect it to my notebook for reality test of application with real location data. Will it work? Can the application running in the emulator get these real data?
Thank you.
I'm not sure if the emulator can communicate with the GPS receiver. You can, however, use the emulator location data to simulator it. Take a look at the MSDN guide to learn more.
I am designing a Windows Phone 8 app and I have been researching location API. However I am only seeing location services for GPS. I don't really want to use GPS for my location app, I only need to a broad cell tower information. I would like to use the cell tower ID and any other information the API comes back with.
Would it be possible to obtain this information currently with the WP8 API?
No, this capability is not currently available in the Windows Phone SDK.
Get location(lat/long) without GPS, just like my location feature in Google maps. I have Google Maps in my mobile (Sony Ericsson G502 without GPS). It works fine without GPS in India.
1.How Google finds my position?
2. When i am searching cellid in opencellid database, it has less number of records for India. but Google Maps works fine in my mobile(India)
3.Is Google uses opencellid database or its own?. if Google uses its own, shall we have access to it database
4.Is there any commercial cellid database for India?
The answer is that cellular phones use various location methods, most were introduced as part of E-911 (Enhanced 911) or equivalent emergency service for other countries (e.g. 999 in UK) or since.
I don't know if GSM or CDMA has any localization protocols or standards itself beyond whatever E-911 and such requires. So I doubt there is a general API for all mobile phones.
Mobile phone localization is done via:
plain GPS
Assisted-GPS
Cellular triangulation / multilateration
Cell (tower) identification (FCC/etc. cellular tower database lookup)
Enhanced Cell Identification (E-911)
Uplink-Time difference of arrival (U-TDOA)
Time-of-Arrival (TOA)
Angle of Arrival (AOA)
E-OTD (Enhanced-Observed Time Difference)
and/or a hybrid of these technologies and approaches.
(Src: Wikipedia / Mobile_phone_tracking)
These approaches vary in accuracy and precision from ~35 km (22 mi) to ~5-10 meters (16-32 ft) or better.
3.Is Google uses opencellid database or its own?.
It appears that they have their own database without a public documented API.
4.Is there any commercial cellid database for India?
I don't know.
Google almost certainly uses a proprietary database. They admit as much as:
This involves analyzing the Wi-Fi access points around you and your computer's IP address, and sending this information to a Google server to then be translated into a location that we can show on the map.

Google Street View cars have been known to collect data about wireless access points that could be used in such a database.
Skyhook offer an API for geolocating devices based on Cell ID, Wifi access points, and if available, GPS. The iPhone OS uses this to provide its CoreLocation functionality.
They have SDKs available for most mobile and desktop OSes. It's very good, but you'll have to speak to them about licensing.
As other posters have mentioned, both Skyhook and Google maintain proprietary databases of location information for WiFi SSIDs and cell tower IDs. I believe Geomena is trying to start an open database of located IDs, but that it doesn't yet have the breadth of coverage that the proprietary competitors have. Google also provides a simple client-side JavaScript interface for IP geolocation (called ClientLocation), which might be just accurate enough for some applications, and a wide variety of IP geolocation databases exist.
If your application is web-based, you can take advantage of the W3C Geolocation API, which abstracts away the particular geolocation technology and provides your website user-controlled access to whatever geolocation method the browser chooses to use. On the iPhone, Skyhook's database is used to locate the phone with cell tower or WiFi or GPS location; Firefox uses the Google Location Service, which uses WiFi triangulation and falls back on IP geolocation.
Using some abstraction layer (like the W3C API) can have real advantages if you want your application to work across different platforms which have their own location methods, if you want your application to degrade gracefully when only rough methods of geolocation are available and you want your application to get the advantages of additional precision as your customers upgrade to devices with GPS technology.
