I'm not sure if this allowed on here but please let me know if it's not. I'm wondering if anybody could point me in the direction of some great learning resources for Socket.io. I'm particularly interested in learning how to use a mobile device as a controller for a desktop web-browser application. Any nudges in the right direction will be extremely welcomed.
This is a great resource for learning socket.io
As far as usage of mobile device as controller for a web-app is concerned, there are clients out there for Android etc which interact with Node.js and socket.io server.
socket.io-java-client is a client for android which can serve this purpose for you. You can emit something from android to your server and from server to web-apps or from directly android to web clients.

I am a developer and I have a Bluetooth Lamp that has RGB and Day/Warm Light that has a third party App to control it.
My goal is to do some automation with my Lamp.
Is there a way to read what this app is sending to my Lamp is order to simulate its functionality? The thing is this App is not possible to integrate with my Google assistant so I am trying to find a way to do it my self by making my own mobile application to control my Lamp.
Or maybe my question should be something like: is there a generic App that can control generic Bluetooth Lamps?
Any information is greatly appreciated.
You could either hack the hardware itself, or you could simply snoop on the communications to hack in to the lamp controls.
Otherwise, I would check out integration platforms like IFTTT, which allows some customization of control with proprietary systems.
I'm trying to build a simple web app that reads the clients' serial port that is connected to a barcode scanner. I have done this using ActiveX but it only works on IE browsers, i have heard that I can now do this using node.js and serial-node. Can someone tell me if this is even possible using these two technologies? Also if anyone can direct me to a working tutorial on how to do this. Thanks!
You can't read the serial port of the web app's client's computer using serial-node, no. Node.js and serial-node run server side, they do not have direct access to the web clients' hardware.
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.
How can i make my bluetooth Chat application developed in J2ME find only devices that run the application?
Make sure your server app use the same UUID as your client apps. Many examples can be found here.
I'm currently thinking of developing chess code with multi-player facility connected and played via bluetooth. For that I need to chalk out the phases, i mean systematic modules, that I should follow to develop the game. If anyone can state it or have any link that can help it out, it would be great.
Another thing I am developing this in J2ME, so can anyone give me an idea about the way to connect the game in two mobile devices through bluetooth in J2ME. I mean to say the class or file that is used to connect the gaming devices.
For the second part of your question: you need to make an SPP (serial) connection between the two devices, with one acting as a client and the other as a server; see this tutorial for more information.
Then you need to create your own protocol to allow the two devices to communicate everything they need to.
This will only work on handsets with JSR 82.
