In Sony DSC-QX cameras is it possible to access to the API via NFC?
I think no, and probably it's a stupid question.
Sorry that is not possible. The Camera Remote API is only accessible over a WiFi connection.

I am using Xam.Plugin.GeoLocator from here to get the geo location of a user in Xamarin.Forms project. This is working great when the device is connected to Internet. I need to capture the Lat/Long coordinates of the user when the device is not connected to Internet.
How can this be achieved?
As per comments above, The GeoLocator plugin returns what the OS supplies, so yes, if you have no cellular/wifi but the device does have a GPS connection, then that is what is returned. i.e. If you request a high/fine accuracy than the GPS might be used instead of Google's location services using the cellular or wifi connections even if they are available. Same basically for iOS, but using Apple location services.
We're talking about BLE. Right now Im using the Plugin.BLE library and it's working quite fine. Now Im in the need of using the LE Secure Connection (with the "just works" method) in order to send/receive encrypted data.
I've read lots of documentation about how the protocol works, but have no idea of how actually implementing it in Xamarin and wasn't able to find anything on this.
With the Plugin.BLE one can take advantage of a very simple APIs to connect to a Device.
Is there any library that provides similar simplicity and enabling an LE Secure Connection?
If not, how can I connect in Android & iOS to a BLE device using a secure channel?
Thank you very much
The pairing is handled by the Bluetooth stack and not by the application, so you can't affect this in any way. However, from Marshmallow and onward, BLE pairing will use Secure Connections as long as the second device supports it. Not sure about iOS.
Hi I want to create an app using google nearby message api. I want it to be completely offline.
Is it possible? Does google needs internet connection for using this Nearby api?
I know it uses bluetooth and WIFI things to share the data!
I want to know whether it needs internet connection at its initial stage? since it needs to retrieve some token from the cloud.
Help me in this!
Thanks in advance!
Yes, Nearby Messages requires devices to have internet access. Discovery is accomplished via BLE (Bluetooth Low Energy), WiFi, and audio (using near-ultrasonic frequencies), but the cloud is needed for message delivery after discovery. Nearby doesn't yet provide a pure peer-to-peer solution.
does anyone know if its possible to host the receiver app for chromecast in a remote host, such as heroku? Is it only possible to find my chromecast device if its in the same wi-fi network?
You've got two separate questions here.
1) Yes, the receiver app can be hosted anywhere, and the vast majority of them are on a remote host rather than served locally. When you register your app with the Chromecast SDK console, you will have to submit, with the appID, the URL where the receiver app is located. Keep in mind that if your app is 'published' (available to all rather than just to those Chromecasts you whitelist), then your host much be https:// enabled, whether it's local or remote.
2) I think you're asking whether or not a sender app can find a device that's not on the same wi-fi network? Generally, no ... but at Google I/O this summer they did discuss a feature that would allow people not on the network but close enough to the Chromecast (i.e. in the same room) to communicate.
If I'm misunderstanding question two, please clarify.
Could I disconnect to wifi programmatically in Cocoa?
For the Mac, see the CoreWLAN Framework. Specifically the disassociate method of CWInterface. On the iPhone (since you tagged this cocoa-touch), I believe this operation is restricted (ie, no supported API exists for applications to configure network connectivity).
