Tapi3lib.ITAddress does not return all devices - c#

In an effort to automate some phone calling processes and integrate TAPI3 with another application, I am using to following code that was found as a sample;
tapi = new TAPI3Lib.TAPIClass();
tapi.Initialize();
foreach (TAPI3Lib.ITAddress ad in (tapi.Addresses as TAPI3Lib.ITCollection))
cbLines.Items.Add(ad.AddressName);
This code fills the devices in a dropdown and the dropdown only contains one device and it only shows from my computer. I tried installing the PIMphony_6.8_bld3200_XX_Alcatel on other computers where i add the IP address of the PBX device and a phone number (ex: 106) but it does not even show in the list the one device that i can see on my computer. I whatsoever have no idea what and how i managed to be able to see the device on my computer when i run this code. Obviously i am missing something. The devices we are using are Alcatel and the phone can be controlled by this app only on my computer. (i can provide the zip file containing PIMphony_6.8_bld3200_XX_Alcatel if needed). So the ultimate goal is to be able to see telephone lines on all computers so we can control them from the computer.
What am i missing Tapi3 experts? is it a missing installation on the other pc's ? and why only my device shows up?

You need a 3rd party TAPI driver installed, it might be on a DVD with the PBXor on some support website, but some manufacturers charge extra for it. This PIMphony looks like a phone control tool but that does not guarantee it is using TAPI under the hood, it may be using some propitiatory protocol.
I don't know TAPI3 but if you use TAPI correctly you should see 3 to 4 standard windows builtin devices (like WAN miniports) even if you have no drivers installed.
You need a decent test tool to compare results with, I would recommend phone.exe, it is kind of the standard test tool in the TAPI business. But it's getting harder to find online these days, here is a link to a slighly extended variant that google got me quickly: https://helpdesk.estos.de/Knowledgebase/Article/View/82/3/howto-ephoneexe--tapi-test-tool

Windows 10 Pro -version 1803 bluetooth Profiles Access

We are looking to access and use Bluetooth profiles in our WPF application using C# in Visual Studio 2017.
Issue details:
Platform: Windows 10 Pro - version 1803.
Issue brief: We are trying to access Bluetooth profiles via desktop(c#) of connected phones, however on windows 10 the profile show enable but the profiles are not working eg: HFP connects, however, the voice is not heard
We have tested this on following Bluetooth devices:
1.Bluetooth CSR 4.0 Dongle (CSR8510 A10) (Note: this Bluetooth connects and show HFP and works as expected, however, the Bluetooth does not show on the device list and hence we cannot connect programmatically using c#)
2.IOGEAR's Bluetooth 4.0 (Model GBU521W6) (Shows on device list and our application can detect a device, however, HFP is not working as expected both from the application or from normal device section)
Required Profiles:
1.Hands-Free Profile (HFP)
2.Message Access Profile (MAP)
3.Phone Book Access Profile (PBAP)
We have Already Tried with following:
Updating drivers
Tried uninstall install many times
Used android, ios, and windows phone's
Side note: Our application with same code works on windows 7
MAP abd PBAP is not a problem because both are OBEX based (which is RFCOMM).
However there can be some problems with HandsFree. It works great with BlueSoile drivers. But with standard microsoft may not work.
The first step it to use BluetoothSetServiceState with HFP UUID to tell windows to install drivers for your device's HFP profile. If function succeed you should see 2 audio devices appeared in your system: one is Inout and other is Output. You can find them using any media API (DirectSound, legacy API).
To be able to work with PBAP and MAP you need anyhow connect to your device through RFCOMM. WinSock or any other way is good.
Please note that the method above works only with Microsoft Bluetooth drivers. Other drivers (BlueSoleil, Toshiba) have absolutely different API so you have to add it into your application if need to support them.
Or you can simple take a look on BluetoothFramework

Reading logcat on android from c#

I am looking into making a c# program that will read in the logcat output from an android device and read it in to the c# program.
Initially it should do this while the phone is connected and it shouldn't require a specific app on the phone to be installed for the c# program to be able to retrieve the logcat output. Also the phone shouldn't require root access.
Is this something that is possible, I can't find anything on Google that says its possible but thought I'd ask on here in case someone has some useful information.
Thanks for any help you can provide
The most practical answer is to execute the shell command 'adb logcat' from your C# program and capture its output.
The only requirement for the device is that USB debugging be enabled in the settings menu.
The host PC will require that the android developer tools and appropriate USB driver for the device be installed. This can, unfortunately involve a substantial amount of hassle, especially finding the right drivers for windows hosts.
More complicated approaches would be to duplicate the functionality of the adb program (it is open source) and/or USB driver in your program, or to install an app on the device with the read logs permission which sends them to you - or even run an ssh server under the app userid so you can connect in and obtain them.

Bluetooth send/receive text without pairing using C# on 2 Windows 7 Computers

I have read that pairing is a must before communicating anything over bluetooth, but I want to know,
Can I create an application which would read a text which is
broadcasted by another bluetooth App without being paired.
Because we can see the names of other bluetooth devices around a device. So can't we set our bluetooth radio to a state that it would read any bluetooth boradcasting text message.
Example: there is createInsecureRfcommSocketToServiceRecord() & listenUsingInsecureRfcommWithServiceRecord() in android but aren't there such in C# for windows?
Thanks
My Ultimate Goal :-)
is creating an application running on windows 7 PCs, which create instant Bluetooth network for peer to peer file transfer and chat
Scenario
There is a group of people, each has this app on each computer, one wants to share a file, (may be an eBook, PDF or anything) with the rest. He sets his network "net" ( or any other name) in his app configuration and others also put that same name on each app. Finally each user can see the list of other Bluetooth nodes around them in their apps display, configured to same network name "net". so each can send files to selected nodes in the same network.
Design
Each user only turns on the Bluetooth radio and then enters a desired Network name in then app
Each application on PCs will communicate iteratively to reachable Bluetooth devices, through temporarily created connections (without pairing or user involvement), check their network names and list discoverable PCs with similar network names
Then they will share these lists among each other, so one PC knows the computers in their same network even though they are not in range directly.
Send files from one computer to one or many computers through a path resolved by an algorithm, even send chat texts.
All of this is going to be achieved through simple temporarily Bluetooth connections established between each application time to time, which requires no pairing or authentication, other than the Network Name. ( Because I don't know how to create Piconets using C#, or how to create bluetooth routing protocols.
No other security is implemented.
Please let me know of any other better design or way. Thank you very much for reading the lengthy text. Also include any helpful code which can help me achieve the above.
I make tens of un-paired connections every day... I don't know where this rumour comes from. :-,)
As you note on Android the default was for an authenticated connection -- maybe that's where the rumour started from? Even there, as you note, there are ways to request a 'pairing-not-required' connection e.g. listenUsingInsecureRfcommWithServiceRecord.
So, on the Microsoft stack on Windows one uses Bluetooth (RFCOMM) through a socket (winsock). By default that connection does not require authentication (pairing), nor encryption -- in fact to request auth/enc one must set a socket options. Similarly with Widcomm, you specify when you create the connection what security level you want, and that can be 'None'. Similarly on Bluetopia, similarly on BlueZ on Linux.
So if you use my library 32feet.NET, just use BluetoothClient and BluetoothListener and do not set cli.Authenticate=true etc. :-)
Some code examples
What's your ultimate goal? I've just realised that you were asking about file-transfer in another question... :-)
Anyway for transferring text... On the server-side have code like shown at: http://32feet.codeplex.com/wikipage?title=Bluetooth%20Server-side and on the client like: http://32feet.codeplex.com/wikipage?title=General%20Bluetooth%20Data%20Connections Don't know if you know TextWriter/-Reader sublclasses on .NET, anyway on one side:
....
var wtr = new StreamWriter(peerStream);
wtr.WriteLine("hello");
wtr.Flush();
and on the other:
....
var wtr = new StreamReader(peerStream);
var line = wtr.ReadLine();
MessageBox.Show(line);
There's code in the BluetoothChat which pretty much does something like that.

Mock Device connecting through USB

I have a device and the drivers for this device. What I would like to do is build an application that mocks a USB device to communicate with a third party application.
More specifically, I am attempting to build an application that can mock a USB device that mimics a Microsoft Zune. I want to make it so my application can register as a zune device and then communicate with the client. I have added several DLL's to my application in order to attempt to determine the calls that tell the software a connected device is a legitimate zune, but so far I haven't had much luck.
I'm new to this type of development - that is mimicking hardware devices, and I'm not very experienced in importing dll's that were written in C/C++. I am using Visual Studio 2010 (.net 4.0) to develop my app, and I would appreciate any help anyone can offer me towards mimicking the hardware. I do have the device drivers, which Visual studio refuses to reference directly. I also have an actual physical device, so I can see what the drivers are that it uses in Device Manager.
The goal is as follows
Application registers itself as a usb device, mimicking a Microsoft Zune in a similar fashion to how Virtual Clone Drive mimics a DVD player.
Application is recognized by zune client as a valid microsoft zune.
Zune Software works with application as it does the hardware device (syncing, etc)
I just found something called the Device Simulation Framework, which might be exactly what you need. It will still require significant research into how USB works to finish your solution, though. And probably still typically done using C or C++.
The Zune uses a modified version of the MTP protocol called MTPZ, but I found this sample using the Device Simulation Framework to simulate a regular MTP device. It's called The MTP Device Simulator. I can't tell if source code is available.
Are you able to replace the DLLs used by the zune client software with your own DLLs? In that case, you could wrap the original DLLs with your DLLs and intercept the operations.
Update: To find out the signatures of the functions in the DLL, take a look at the Dependency Walker tool, which will list the exported functions (and lots of other information). I'm guessing you will want to write your replacement DLL in C.
Otherwise, you'll have to write drivers that register a USB device with the proper endpoints. I'm not sure how to do this on Windows - I've only done USB coding on the firmware side, not the driver side. You should be able to use any tutorial for creating a Windows USB driver, like Getting Started with USB Driver Development
Zune specifics information might also be useful. Perhaps this blog post and its sequels could help: Inside the Zune/USB Protocol: Part 1

How to use computer's Bluetooth to send Wallpapers to any cellphone, in C#?

I'd like to know if it is possible how to do it, because my client asked me if the program I'm developing could also send wallpapers to nearby cellphones(my program will be in a place with many people passing by, so it would be good to have the bluetooth feature).
Thanks!
it can send pictures as files, users then may set them as wallpapers.
Unless the phone and the computer support bluetooth and are connected, you cannot. You can send the files to mobiles over bluetooth. 32feet provides a nice library to perform bluetooh related operations. Try that.
Hope it helps.
To do this you would need to
Make sure each user's device is paired to your bluetooth "sever"
Create the ability to auto connect and send the file.
On your phone's application, receive the image file and set the phone background - this will be different for each type of phone's OS. I would assume you are aiming towards Window Mobile Devices, since you are using c#.
The first step i see as being the difficult step as each phone much "register" the bluetooth of the server to be paired with it.
