I need to run an application in my ipad which has to talk wirelessly to a controller. The controller communicates on serial as well as RS485 port. It doesn't have a wifi adapter.
What are the options for me to do this ?
One thought is, I have to buy a wifi to RS485 adapter which I will attach to my controller and then my ipad can connect to the controller through the wifi adapter. Is this feasible? My doubts are because, I am not sure whether Ipad has the capability to open a raw socket connection to the remote wifi adapter (on the controller).
If not, then what are the other options which are available for me ?
If you are comfortable with fairly straight forward electronics and programming, this is how I would do it.
I would forget about having them talk directly and instead use the internet, you can get cheap controller called an Electric Imp that you can create code for using their online portal to connect your device to the internet, the device itself connects up using wifi and its own secure VPN.
Once you have it connected up you can create you own webpage or app to talk to their cloud, this has the added advantage you can now control your device wherever you can get an internet connection and your device can continue to interact to the internet even when your ipad is off.

I need to enable multiple devices to communicate with each other using OSC protocol which runs over IP protocol etc.
I have two wireless routers, one of them is capable of providing internet access from SIM card.
What I want to accomplish is:
provide all devices wireless connection for communication between each other
provide all devices connection to the Internet
avoid spending data from SIM card when my devices communicate with each other
This last point is what I can't solve - in my mind it should not be a problem. If I understand it correctly, I am creating a WLAN and there is no need for passing the data to the internet provider (or asking for data from him) and the router should act like a switch and route the signal from one device to another one if the IP and port is correct.
I have router TP-Link Archer C6 ; router TP-Link Archer MR200 ; Windows laptop ; Android phone ; iPad.
What I want to accomplish is remote control of DAW Reaper (running on Windows laptop) over Web Control Surface or OSC Protocol with TouchOSC app or Open Stage Control app.
I will appreciate any help!
Thank you very much in advance,

I have an iOS application with a tableview which I would like to send text strings via USB to my Windows computer indicating which cell was selected by the user.Anyone have experience with this type of interface?
I've written a blog post detailing how to achieve this here.
http://thecodewash.blogspot.com/2017/05/communicating-with-your-ios-app-over.html
To answer your question (so this answer isn't just a link), yes it definitely is possible to achieve this utilizing the USB Multiplexing Daemon (usbmuxd) program that is usually installed as part of iTunes. This program can create a socket connection to your iOS device through the USB cable, and allow you to communicate via that socket connection like you would any other socket. The link goes into much more detail.
Hope this helps!
(In short) Yes, you can communicate with ios application via normal socket communication by using ITunes which acts like proxy. In this model your ios app acts like server listening for connection. Windows app must connect to iTunes on port 27015 and estabilish connection to specific port (used by ios app) on connected via usb device. This is done by using a special MUX protocol described here
I Need to create an iOS application and a PC application, the two need to be able to exchange data over Wi-Fi (either direct or via a wifi router).
The iOS app will act as a remote control for some of the features of the PC app, for instance, if a video is playing on the pc application then the iOS app will have buttons to control playback on the PC such as play, pause, stop etc, when one of these buttons is pressed then I need to send some bytes to the pc over wifi.
My questions are:
how should I go about sending data - Wifi direct or via wifi network that both devices are connected to?
can anyone help with example code to connect or send data to a specific device over wifi for either methods?
to be clear, I don't need help with creating the applications themselves - only the wireless transfer of data between the devices using the Wi-Fi radio whether it be direct or via a router.
The main question: is it possible to initiate a connection/send bytes under iOS over wi-fi to a pc on the same network or via wifi direct?
Help with the method to do this or example code would be helpful.
I am working on a project in which I should connect an iPhone to an accessory via WIFI.
Some blogs spoke about ExternalAccessory.framework but this one is used for establishing connection via Bluetooth.
What library should I use to achieve this ? Could any one please point me to the right direction ? Thanks.
(Assuming that you don't know the ip address of the device you want to connect to)
From an iOS standpoint you want to use NSNetService to discover devices on the network which you can connect to.
This requires that your other device can use mdnsresponder to publish its details onto the network such that it can be found and connected to.
If you do know the ip address (or, once you do know it) then you can use NSURLConnection / NSStream to connect to the device (depending on what capabilities it offers).
So I have an ejabberd (XMPP) server setup on my MacBook. Connects fine with Simulator, only intermittently on the device. The two times it hasn't connected were at cafes that had sign-on gateways for their Wi-Fi. I know nothing when it comes to networks, but I'm guessing this is a Firewall thing?
I'm supposing I can't get around the firewall without an elaborate workaround.
I've found that turning off Wi-Fi on both devices and turning on tethering so that both devices are communicating via data works. However, I'd rather not do this as my data plan is limited and I'd like to be freely internet-connected while I work.
Is there a way to setup XCode to have the phone use the USB connection to access the server on the MacBook? Or maybe some other way I'm not imagining?
Bluetooth doesn't work.
I don't believe that the problem is with some kind of firewall on the network…
Try using the local IP address instead of the hostname, It will change from network to network. To get it, you can open the network utility
In this case it would be [xmppStream setHostName:#"172.16.1.2"];
