This question is simple:
Does media query "handheld" include tablets?
Note: I am aware that there are some devices, like iPhones, that do not use the media handheld.

handheld :
Used for handheld devices (Smartphones and tablets do NOT listen to this!).

I have a "Serial to USB" device with two endpoints that streams data that I want to access.
Tried several IOKit methods found on Google including "code less" .kext but no luck.
Is there a simple way to do this ?
You could try using the HID API for OSX.
Can we control multiple DSC-QX100 cameras using the Camera Remote API SDK from an iPad OS7?
The objective is to cause multiple cameras to "snap" picture at the exact same time. Perhaps each camera has an address (serial number)...can the software communicate with all cameras at the same time using multiple addresses? Need is limited to still photos and so-called fast, rapid photography. Video not necessary.
If so, how?
Unfortunately you can only control one QX100 lens at a time. This is because the lens connects over WiFi and you are limited to only a single WiFi connection at once on an iPad. It may be possible using a desktop PC with multiple wireless cards installed but that would be the only way.
As the Sony rep said, there's no way to do this with "officially supported" techniques.
The reason for this is that the camera acts as a WiFi Access Point (AP) - so while multiple devices can connect to it, most mobile devices can only connect to it and not anything else (since iOS and Android don't support connection to multiple APs simultaneously). This is also why you can't use other network interfaces when connected to the camera. (I don't know about iOS, but Android always prioritizes WiFi over cell network data, for example.)
Android devices have a feature called "WiFi Direct" that provides more flexibility in terms of peer-to-peer interconnection, but iOS does not support WFD. The QX100 DOES respond to WFD invites, and you can accept a pairing request with (if I remember correctly) a long-press of the shutter button. However, the official app only supports normal WiFi AP connections.
I have not yet attempted to see if using Sony's remote API in combination with the (unsupported but apparently present) WiFi Direct capability works.
More info on Wifi Direct and Android can be found at http://developer.android.com/guide/topics/connectivity/wifip2p.html
Marlin SONY, I disagree, wifi is Ethernet and by definition can handle multiple devices on the same network. If you run a phone or iPad as a hotspot and connect multiple devices, it works.
Multicam Switcher Basic is an example of a free app that supports cutting together multiple camera angles live. Unfortunately the app is still being developed so features like third party camera support isn't included, but it does show what is possible and awaits development.
I think this should be possible. Apps like CollabraCam™ (Multicam Social Video Production) or RecoLive MultiCam prove that is possible to use mulitple cams simultaneous.
I need someone too to develop an App to be able to use "two" sony dsc-qx for 3D shoots. Please, if You know how or who can do this contact me email#3-d.re
Is there a way how to get list of all devices connected to the Bluetooth peripheral?
I want to connect to iBeacon and check if another iPhone is connected to it.
No, two reasons why not:
iBeacons are not connected to the iOS device, iBeacons are broadcast only and no back communication exist from the phone to the beacon.
Knowing details of other BT 4.0 Centrals connected to a Peripheral are not in line with the the privacy features of Bluetooth 4.0. iOS and other Centrals are are using resolvable private addresses, in order to avoid situation like you are describing.
#barbazoo is correct that you cannot do exactly what you are asking because iBeacons only transmit data -- they have no idea what devices see them.
You can accomplish something similar, however, if you have an app running on each of the iOS devices you mention, and you have a server where you can build a web service. The web service would expose two methods:
reportIBeaconVisible(iBeaconProximityUUID, iBeaconMajor, iBeaconMinor, myPhoneAdvertisingId)
queryVisiblePhones(iBeaconProximityUUID, iBeaconMajor, iBeaconMinor)
The app would report each iBeacon it sees using the first method, passing the iBeacon's identifiers, along with the phone's advertising identifier to the server.
The app could then use the second method to ask the server what other phones have seen the exact same iBeacon, which would return a list of phone advertising identifiers.
You'd have to have logic on the phone to only report data to the server at a reasonable frequency. You'd also need code on the server to automatically delete phone records in the list if the phones haven't reported seeing a beacon in a certain time interval.
I've looked over the IOBluetooth framework what feels like a dozen times, but I can't for the life of me find a way to retrieve the Bluetooth device address for the current device. I've written an application that scans for devices in range utilizing IOBluetoothDeviceInquiry, but this doesn't seem to offer up the address of the device doing the scanning.
How might this be accomplished programatically? (Without opening up System Profiler)
[[IOBluetoothHostController defaultController] addressAsString]
or getAddress: if you want a BluetoothDeviceAddress.
I tried GNUBOX which use bluetooth to connect to my computer then to the internet. It's very painful to set up (under windows more than under linux, but it's still painful, it works 1 time on 3).
I own a Nokia 6630 so there is no WLAN support. Is there any emulator? I'd need to know something like max width, max height etc... usability in general, any hint?
This may sound silly but you could consider getting a mobile tariff with unlimited data. In most European countries these are now available and are not too expensive.
I don't believe you would get a solid experience from any emulator.
Don't know if you're only limiting to the 6630 or not...if not, Opera Mini has a free simulator.
If you find yourself needing to do more testing on multiple devices, there's always Device Anywhere...but it definitely does not meet your requirement for free.
Can you use a data cable and IP pass through?
Since the 6630 is a Symbian phone, you should be able to use GNUbox to handle the connection. See http://xan.dnsalias.org/gnubox/
Keynote's MITE just launched a free version for content testing; it includes the 6630 along with more than 1600 other profiles and 11,000 user agent strings. You can access via LAN get the protocol details.
