Sending A Command From Android Phone To Computer Through Bluetooth

[JazzaWil]

So basically want I'm trying to do is send a command to the PC through my phone. If i click a button i want it at this time to lock the PC. This works when on PC but I'm not sure how to send a signal via bluetooth
 

Does anyone have a guide to where to find this, or a solution? Would be much appreciated

Well, in that case I hope you enjoy reading googles documentation.

https://developer.android.com/guide/topics/connectivity/bluetooth.html

 

If you are impatient like me who just wants people to tell you the answers instead of doing the homework and reading the textbooks, go post a thread on stack overflow. 

https://stackoverflow.com

 

 

Edit: you also need to develop the client app for windows. Go read Microsoft documentation on how to do that. (If you are developing for windows pc)

I've tried stack overflow and haven't gotten anything yet. I'm not sure really anyones tried to do this where they have a android device interact with the pc directly but who knows. But hey documentations better than nothing. Client apps easy mode just the connection and the sending of the command

Before you get too far, the PC in question has bluetooth capabilities, right?

 

You could also send the signal via wifi, and use mac address binding on your local network to ensure the PC always has the same internal IP (you'd have to have a static IP to be able to reliably lock it from outside your home network though)

There are plenty apps on android play store that does exactly that. Microsoft has release an app that allows you to remote control your pc with your phone. Do you still want to code your own? 

 

You should have some strong knowledge of both windows(win32) and Android APIs before even attempting. (Assuming if you are doing it for android and windows devices)

I have an adapter to make the computer bluetooth compatible 

Edit: so thats the reason i use bluetooth not wifi. so i have a portable option

Yeah i could also use teamviewer or chrome desktop support but this is to execute code like the code for locking a computer remotely from the app. I want to do this for the sake of making it. As i said before i've made this work on pc it's just now getting that command executed remotely

Just like most things in programming, it's often helpful to prototype and break things down. Before even thinking about the app, start by just making the most basic system that communicates over bluetooth. A very simple client on the PC, and a very simple app on the phone, just to get through learning how to actually send/receive packets through bluetooth. Once you figure out how the basics of bluetooth communication, then you can start applying that knowledge to your more complicated use case.

Edit, sorry, I didn’t see your original post. My previous post would not be relevant or necessary at all. Read Android documentation.

See reason above

Maybe look at Xamarin? It allows you to develop an app for android in c#

 

And the way I see it, there's three main components to your project:

 

1) Clicking the button on your phone

2) Communicating via bluetooth

3) Locking your computer

 

Maybe try working on each part individually before trying to put the whole thing together into one.

I'll definitley try that, i have everything but the communicating via Bluetooth down but again thanks for the suggestion ?
