I am trying to implement zigbee OAD using CC2530.
Can anyone please tell me all the steps that are to be followed to implement OAD functionality..
P.S.
I have gone through " over air download.pdf " and
"developers note - Over air download.pdf" provided with zstack documents. but the ZOAD.exe fails to join network..
Some time ago I implemented OTA using MSP430/cc2520 and z-stack.
I chose it over OAD as the latest was a proprietary solution from TI.
When using OTA instead of OAD you use the OTA Server, which works good, enough at least for development.
Unless you need OAD, take a look to OTA, it seemed to me to better documented and, except for making my code to fit into the memory and using a non-supported external NV memory, the rest was pretty easy.
Hope this helps

How can I interface my Fingerprint Sensor using VB6? I've already made a login form but I need help using the fingerprint sensor for the security. Please help me, thanks in advance.
Here's a good starting point: Getting Started with Optical Fingerprint Reader – R305. It's for the 305 but the overall setup should be very similar if not identical. Most importantly you will find an SDK for R30X modules in the Resources section of this page. It includes drivers, demos (with source code), SYNO API, user manual, etc.
Also, Vishnu M Aiea wrote a C++ library to handle communication with the R307 sensor: R30X Arduino Library. You should consider using this to handle the communication aspect since it's already been built for you. You might need to get it compiled into a DLL to use with VB6.
There's also an article he wrote about the whole setup process: Interfacing R307 Optical Fingerprint Scanner with Arduino
These links thoroughly explain how to set everything up. I think with all this information you should be able to make a lot of progress and come back to Stack Overflow with more specific questions.
i try to find a good combination of libraries for managing a real-time communication (client/server) using Haxe (only Haxe, not openfl or other framework base on Haxe) targeting flash (swf) for the client and no preference for the server except don't use neko.
The goal is to make a simple tchat and put a display representation of all clients on an aera. Each client can move his representation in this area, and the other sees the movement.
I find some Lib to make this :
https://github.com/soywiz/haxe-ws
https://github.com/MattTuttle/hxnet
haxe-js-kit
But I'm not sure of the best way to adopt.
Do you have any suggestion/remarks/tips to choose the better way ?
Disclaimer: I wrote the library that I am sharing here.
My somewhat new library mphx may be able to help you. It can manage 'rooms' of connections, allows client to server and server to client messaging in the form of events, and best of all, is cross platform. It also works in the web with websockets.
It was originally an extention of HxNet, however I wanted it to be easier to use. Connecting and sending a 'message' with data just takes a few lines.
I have a few examples in the github repository, the simplest being the 'basic' example. One of your requests you have is that it doesn't rely on one of the big libraries (open fl, etc) and mphx doesn't. The basic example proves that, and only runs in terminal. That being said, it can be used with haxeflixel, for that you can see the other examples.
It sounds like your main goal is to have simple, graphic multiplayer. For that you can look at the 'movement' haxeflixel example.
Documentation is still a little skim, and the code is alpha, so it might change or break. That can probably be said for most of the library's you listed though. The best way to install it is like this
haxelib git mphx https://github.com/5Mixer/mphx.git
That will not install the examples though. To run them, either download the repository as a zip, or just git clone it, and go into the examples folder.

I need support in SignalR for Android client. I am using following client SignalR/Java-Client but unable to know where to start :) We are completed .net self host & working fine. But only problem with Android & iPhone. Can any one please guide me how to start the next steps for Android & iPhone.
You don't give a lot of details, so it's hard to give a concrete answer, especially since your question is very broad to begin with. Nonetheless, you should have a look at the official samples for the Java client, to get you started. If you have implemented the server side yourselves, and know your Java, it should be pretty easy to figure out from the code provided in these samples. The Java client is, in my experience, very easy to use.
As for an iOS client, a Google search came up with this library. I have never used it, and it looks like it's not getting a whole lot of support, but you could always give it a shot.
I need to play audio from my Qt project deployed on Raspberry Pi. Everything works fine except that I don't get any audio out, instead I get the following error message
defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"
After googling around I have come to the conclusion that the problem is that Gstreamer is not installed and recognized by Qt (more precisely gst-omx). Also, I have tried for many days to proper install gst-omx on Raspberry Pi without much luck.
Can anyone guide me to how I solve this issue???
One hack would of course just to use an external application to play the audio like mpeg321 and just start it up by QProcess, but I need to control volume and be able to start, stop, and pause, so such a solution is not really feasible...
Short answer: Well man, you found what many people find. Qt won't work with the Raspberry Pi just like that. You might get it to work, but without accelerated decoding it will just run as slow as it can get, and crash every few seconds. Sorry.
Long Answer #1: Qt needs to be compiled with special routines in order to get access to the omx stuff. This is, accessing the dedicated hardware embedded into the board which handles accelerated decoding of the h.264 (an a few others) files.
You have two choices, one is to build a special module from here: Carlon Luca's Github or you get a baked in Raspbian image with everything compiled in place from here: The Bugfree Blog. If you are a newbie on this, building it might give you a very hard time but you will get rather stable code and your choice of Qt and an up to date raspbian. The precompiled image on the other hand is just a matter of download, burn and run, very easy!, but it has some older code, so it has some rough edges and it's a bit unstable (almost every video i've tried shows garbled for the first 2-3 seconds and had crashes from time to time), also you will get Qt 5.1.2 without some of the speedups Qt guys added at 5.2.x.
Long answer #2: There are indeed gst-omx libraries which supposedly work with Qt and supposedly are way more stable, I've never tested them. But you can check for yourself Google: Qt Bellagio, I tried to post the links for them, but had not enough rep. You will have to build your own Qt btw.
Update:
If what you need is video playback, i forgot to mention Boot2Qt for the Pi, but you have to pay Digia for the license. It's called Qt Enterprise Embedded, google it.
Our company is using some software that ONLY accepts input from an "Imaging Device" i.e. a TWAIN device (e.g. scanner).
The problem is that we are receiving our files digitally, so using an actual scanner would require us to print, scan, and shred documents that we already have on the computer, but not in the software.
I was curious if anybody has any idea of how we might be able to work around this problem in the meantime. My first thought was to find some way to trick the program into thinking we're using a scanner, via some new 'imaging device' that would just read in the file, and spit it out to the software, but I don't even know where to begin with that.
We put in a feature request, seeing as how this problem should obviously be addressed in the software itself, but the company is notorious for lagging pretty hard when it comes to updates.
The system used by scanners is called TWAIN, so you'd be looking for some sort of virtual twain driver.
A quick google search will produce several hits, I don't have any experience with the software myself so can't advise any further.
Two such providers I found via experts exchange:
http://www.twaintools.de
http://www.scanpoint-usa.com
OK, months late... but in case you are interested, I have a TWAIN driver framework/toolkit that might let you build this fairly easily, depending on just what your scanning app expects, and how hard it is to read images from your digital documents. It's a Microsoft Visual C++ project. No charge but you'd need our permission to redistribute a driver based on it: GenDS
The TWAIN Working Group also has a sample/skeleton driver, I think it's straight C - and used to have some rather bad bugs (Why I wrote mine ;-) but, it might have got better.
Look for the "sample data source and application" on their download page.
And of course I have a 'commercial' version of GenDS that I use to write TWAIN drivers on contract.
