Given an OpenThread border router (pi+nRF52840) and a Google Nest Aware "bundle", will the Thread network integrate with the Nest app on my iPhone?
May other thread devices (maybe not Nest) be added and viewed in the Google Nest app?
Kind regards
Graeme
OpenThread is not sufficient for integrating with the Google Nest mobile app. Thread provides IPv6 connectivity. However, the Google Nest app requires application-layer protocols to communicate with compatible devices.

I'm a seasoned developer who is jumping into to OpenThread for home automation specifically for Nest products. I'm more interested in exploring the possibility of communicating with Nest devices through local protocols via border routers, local link and local mesh presence of FTD's & MTD's. I'm not interested if it can be avoided to use the Nest API through the cloud and user accounts.
I've started with the Nest Learning Thermostat and I'm prototyping on a Raspberry Pi 3 and have successfully built the Open Thread Posix platform and other steps on their git repo here: https://github.com/openthread/openthread
I am able to ping between 2 platform NCP nodes via ot-cli-ftd, and some, but not all the necessary wpantund(?) services are running.
The above steps describe the direction I'm going, but I'm not sure it's the best or correct way to do so, but makes sense based on what I've read so far.
Since the Nest Learning Thermostat already attaches to your local wifi network via tcp/ip, I'm trying to determine if the thermostat has a built in border router, routing 802.15.4 traffic to wifi? Does anyone know? I've been able to connect my thermostat to my home wifi network, but I haven't found any examples of communicating with it the way I am going.
If the thermostat doesn't have a border router, or the tcp/ip connection is proprietary and not accessible to makers like me, then do I need to get an 802.15.4 platform to communicate with Nest devices?
Thanks for any help you can give.

Today, the Nest Learning Thermostat makes use of Thread technology primarily for controlling Nest HeatLink products in Europe. It does not expose any APIs for control or introspection over Thread right now. If you want to interact with the Thermostat, you'll need to use the Works with Nest (cloud) APIs.
Thread (and OpenThread which implements it) provides only a network layer, but for meaningful interactions, you'll need an application layer on top of it. Nest products use the Weave protocol suite for this purpose. Nest is not quite ready to provide full third-party interactions directly to their products quite yet, but you can begin exploring Weave technology over at http://openweave.io/ -- watch that space for more to come.
Since we need to have a UDP socket to discover the device, and since javascript seems not supporting UDP, is it possible to connect to Sony Camera Remote API with a javascript based mobile app (non native).
As said in the comments, you can use Cordova to do the SSDP discovery.
However, as far as I can see, the API is HTTP-based. So if you don't need discover (can write in the IP address and port manually), then this should be possible to do.
Did you ever get anywhere with this project? I'd be interested in getting some LiveView and controlling a camera using Javascript.
I am working on IoT project over google cloud. I use Publish/Subscribe to allow devices contact each others. I developed the backend system using nodejs, then I will develop Mobile app that will use google library to publish/subscribe.
The problem that I face now is that. Does google have any C/C++ Library for contacting PubSub/googlecloud API or not, and if not, is there any alternative way to keep embedded devices (programmed in C/C++) updated with mobile applications actions.
Note: I need real-time control between mobile app and embedded device.
Thanks
Google Cloud Pub/Sub has a HTTP/JSON based API (under the API Reference tag in the sidebar), so you can roll your own library in this case.
The client APIs that Google currently supports are listed here. If you can run Go or Java on your embedded device (both a lot less common than C/C++ on embedded devices, and usually only supported if you stretch the definition of "embedded"), you can have a fully-supported client library.
I want to develop a FirefoxOS privileged app that can send text messages to nearby devices.
Android app can use Bluetooth or Wifi P2P. But FirefoxOS privileged apps cannot use Bluetooth/Wifi API. These are only available for certified apps.
Privileged apps can use TCP socket API. Is this the only way?
Is there any way to get available IP addresses on LAN?
#Kazhik, unfortunately right now, that is the only way to go. And the explanation for that is that by using the socket API you can implement any protocol on top of TCP, such as IMAP, IRC, POP, HTTP, etc., or even build your own to sustain any specific needs you could have.
Since certified apps can only be included by the oem, access to Bluetooth or WiFi information API aren't a viable option now.
At today's date (September 18, 2015) the WebIDE supports installing certified apps in older Firefox OS versions like 1.3 and in physical devices.
I tried installing the Gaia test apps (these are certified) in one Alcatel OT FireC and everything worked perfectly fine ;)
DNS-SD (part of the Zeroconf specification) allows you to broadcast and receive "advertisements" from other devices on the local network. That requires UDP and TCP permissions, which means a "privileged" app, as you thought. That's not a problem, unless you need to distribute the app outside of the Firefox Marketplace.
There's an implementation of DNS-SD for JavaScript at https://github.com/justindarc/dns-sd.js
For compatibility with other messaging apps, you might want to implement XMPP:

I need to develop a project based on Bluetooth in mobile. Since I am new to j2me I studied some of the articles and run the project until the discovery of devices and services. I need to communicate between devices and transfer the desired files. I search code for client server communication through Bluetooth and got it but I didn't know how to run those code and implement further.
I have go through articles and I can run client server communication. Now I need to transfer the file and communicate to the user which was beyond the limit of my mobile through the another mobile which was within my limit.
JSR82.com has many articles and tutorials about how to use bluetooth from J2ME.
Better you refer the book, "BLUETOTH APPLICATION PROGRAMMING WITH JAVA API" by C.Balakumar. It is helpfull to you.
