I'm working now on ELM327 software which help me to make scan for cars.
but now i'm in the begging , so how could i make My software read from ELM327, also is there's any source code can help me in my project?
It depends if you are using bluetooth or a USB.Usually if you buy an elm 327 device you get the Software to read it. If you want your own software to read it then you have to send AT commands to it, to get responses

I have project that will have multiple clients: web, Android, iOS and probably a desktop version too.
As I see a few technologies that claim to help me with this like Flutter, React Native, Native Script, Xamarin(?) and others, I do not know which ones might fit (and of course I do not want to study all of them only to find, in the end, that something I wanted is missing).
[As I do not want this to be tagged as a "opinion-based" question I selected a few specific questions that should give an objective information on each technology someone might mention - more or less similar to a feature matrix]
Here are a few questions that a technology / framework should pass in order to be a good pick
Can I write a single code and then have builds for separate platforms? Or to what degree can I do that? Does it look decent (native) enough on a specific platform?
What additional installations do I need in order to obtain a build for a platform? (Ex: Do I need to install Expo Client for React Native in order to be able to run the app on device?)
How easy is to access the native API in case I need it? (Run it in background, battery level, screen brightness, services, file system access, etc.)
Can I write also server side code with it? To what degree? (Ex: Can I put Dart on server side?)
What is the level of support from industry and dev community on it? (Is it backed more by a company or community?)
Please mention any other platform that I might not mentioned and you have experience and can fulfill the requirements.
I have a bluetooth enabled CNC(key cutter) that I control it from my phone via an app(ios but an equivalent is available for android). I need to be able to gain access to the machine directly with bluetooth or usb(already tried on pc) so I can try to find the correct memory offsets and values so I can change precoded names, values, for already existing "cutting profiles"(Not sure if these files are in the CNC or the app).
Trying to reverse engineer the app seems like a waste of time until I can at LEAST discern which files to expect are kept on the cnc, and which files are kept within the app.
I have experience with memory editors such as cheat engine, a little C / C++.
I have tried searching for solutions based in Bluetooth, but that is only getting be basic file transfer explanations. The app gives no direct access to files of any kind.
ANY help pointing me in the right direction for where to start with this problem, or reference material you think would be relevant would be helpful.
I have developed a simple software using VB.net, now i want to receive some data from an external device, i want to know if any way to learn "**How to read a hardware transmitted data using VB.net, where hardware is attached to a USB port?**" Any specific book or any way to get this thing learn.
Looking forward to hear from you all.
Thanks & Regards.
I think you should not duplicate the question:-
Still i was searching and found the answer from the following link, so again posting it here so that people should not search more for this. Thabnks
How to get the data from a USB port in VB.NET
Here is what I found. You use the HID.dll to interface the usb ports. And you know the best part? I found some examples.
Here's a link that contains basic examples and tutorial for usb interfacing. The HID Page

I've found a scale, Detecto AS-350D (http://cardinal-detecto.centralcarolinascale.com/AS-PC-Computer.htm), that hooks up to a computer. I was hoping someone could help me figure out how to get the information (weight) from it. I've looked around but can't seem to find any information on it. I've never wrote a program where I accepted data from a device likes this so kind of confused where to look. Thanks.
Update: I'm coding in VB, and the device connects to the computer via serial port.
I developed a serial port programming language in C#. maybe you want to try it. It also has a built-in debugger and it requires .NET Framework 3.5 or above. you do NOT have to install any other programming tools. It is freely available on sourceforge.
If you create a driver simply with the following state, you will be able to get the data from the serial port.
state Init
recv();
end state

If you have any questions, please feel free to ask.
Simply I am asked to write an application for a smart device (smart cell phone), which will get the GPS coordinates from the device itself.
I have no smart device at all. And I am kind of lost among questions like how can I check if the device have a gps by using the code, if it has how can I obtain them in a "standard" way, do I need to be using frameworks like GeoFrameWork?
So, may somebody list the must or most required things I need to have ready?
Geoframeworks GPS.NET is free these days and it's pretty comprehensive so there's no point reinventing the wheel. It's also friendly to beginners which helps. I strongly recommend downloading it and playing with some of the sample apps. It's a bit tricky if you don't have a physical device to play around with but it does have GPS emulation classes that you can use.
All you need is a copy of VS2008 Pro with the Smart Device SDK installed.
