We have an application which is intended for intranet use. It's not available on the web and we'd prefer to keep it that way.
In house the iPad can connect to the wifi and we can demonstrate the website that way. At a customers is there any way of connecting the iPad to the laptop and showing a website running on IIS off that laptop?
The only way I can think of is by attaching a router to the laptop and running a local network that way, not sure if customers would be entirely comfortable with that
We could also look into some kind of VPN arrangement? It would be so much easier if we could connect the iPad and laptop though
thanks
(Edit) Is Bluetooth a possibility?
I did a huge kludge when I needed something like that. I don't really recommend it because it's annoying, but it works to some level.
Connect your phone to the laptop, sharing the 3G connection via USB.
On the laptop, share that USB connection via WiFi.
Connect the iPad to the laptop's access point (WiFi)
The iPad should now be able to "see" the webserver that runs on your laptop

For the purposes of a presentation demoing our app, where internet is not available, I need to connect some iPhones and iPads to a local wireless network (an ad hoc network) from which they will access a local web-server (hosted on a macbook) to send / receive data.
In the past this was simple, but it seems iOS 10 is no longer happy connecting to wireless networks that don't allow it to access apple's own servers via the internet.
As a test, I am able to use MAMP Viewer to view my local sites when both my laptop and iPhone are connected to wifi with internet access, but not when both are connected to an ad hoc network created via the macbook. I can see that the host exists, but can't connect to it - MAMP Viewer reports an error (with no details).
Is there a workaround, or is it genuinely the case that iOS 10 devices can only use a wifi network for web data if there's an internet connection back to Apple? Hopefully I'm missing something obvious?
I was able to get the connection working using an encrypted wifi network offline running from a router, just not an ad hoc network or an unsecured network.
I am working on developing an enterprise application for ios 7 that needs to work offline and then sync with a desktop client (that I also need to write) for data transfer.
My company does not allow wireless or cell data in this area, and would strongly prefer to not use iTunes either.
The question is, how do you transfer data from an iPad over the usb cable to a custom windows program, without iTunes.
The simplest answer would be: iExplorer (http://www.macroplant.com/iexplorer/) plus some kind of a script to automate the data sync.
Otherwise, you can use the ExternalAccessory framework to communicate with the desktop via a USB tether. This would necessitate a desktop client running simultaneously to communicate with the device.
peertalk (https://github.com/rsms/peertalk) does what you want, however the computer side library is only for mac os. Maybe you can port the protocol to windows by looking at that (the license is BSD)
Edit: this guy managed to have it run under linux. It sits on usbmuxd, which also has a windows port, so it shouldn't be impossible.
I am looking for a weekend project to do and I was wondering if this was possible. I have these radios that are programmed using Telnet (to set the frequencies, output power, etc.) and I normally do this with my computer in the terminal. The radios have an RS-232 connector on them and I use a USB converter to connect to my computer. Having a small, portable device to program them with instead of a big, clunky laptop would be great, so what I am hoping is possible is to be able to create a telnet connection with my iPhone. Is it possible to create a Telnet application for my iPhones that can connect to these radios through the USB/lightning port on the iPhone? I know normally when people write Telnet applications for the iPhone, they are using over the air connections like WiFi/3G/4G to connect to the internet, but this radio is not connected to the internet but its own private network of other radios. If it is possible to connect the iPhone to the RS-232 port and accomplish the Telnet connection (also without frying my iPhone with too much current) that would be fantastic. Also, if it is possible, how would I access the lightning port? Thanks!
EDIT: Another possible connection is the iPhones lightning port to an RJ-45 connection. That would work as well. Is this possible? Thanks!
As far as I know, you can always study the specification of the lightning connector, you can find it here : http://en.wikipedia.org/wiki/Lightning_(connector). You can try to play with the SDK, trying to send commands from the iPhone and receiving information through the cable. The problem of that, and I was working in several medical applications with the 30 pin connector and the lightning as well, is you have to spend a lot of time to deal with the specification. The most important part is to understand how the connector works and what can you send and receive through the cable. If not, you would have to build your own connector, which is interesting and can help to learn a lot, but it´s not an easy thing. In a project I was working, we had to build several cables to adapt the signals to connect with the device, in my case an iPad1 and recently an iPad 4 although it works with the iPhone as well. As you know, or you should, you will have to learn about MFI.
You can find some information regarding that point here : Create an iPad app that can send/receive data via the USB cable?, but bear in mind everything goes through MFI, so it has its pros and cons....most of them cons. You can find several information here : https://developer.apple.com/programs/mfi/
good luck :)
I am currently running a robotic's project using an Hokuyo (URG-04LX-UG01 - http://www.hokuyo-aut.jp/02sensor/07scanner/urg_04lx_ug01.html). This one is plugged to my computer using USB. Although it creates the port "/dev/ttyACM0" when I plug it, I can't connect to it using the associated library (serial connection error). Until here, nothing's strange, bugs or misprogramming happens but here is my problem :
When I plug the hokuyo to an USB HUB, which is also plugged to my computer, I can connect to it and everything works perfectly.
My laptop is a samsung 900x3c running Linux Mint 15.
Do you know what an USB HUB changes in the USB communication ?
Is there a link with my laptop ? (I used to face the same problem using an ARM-Based embedded computer)
Is it possible to fix the issue without using any hardware solution ?
If it's not, is there anything more compact than an USB HUB which could fix it ?
Thanks !
Is your USB-HUB powered from external power adapter? URG-04LX-UG01 seems to consume 2,5W/5V=0,5A. This is limit for USB. Laptop USB ports are not so powerful and if device consumes a little bit more than max, then they just cut the power.
Update
The device is USB 2.0 Full Speed. I've seen USB controller, that had problems with USB 1.0 or USB 2.0 devices. Hub presents itself as USB 2.0 High Speed and handles USB 2.0 Full Speed transparently for the Laptops USB controller. Do you have another Laptop/PC to check this?
I'm kind of late on my feedback for that issue, but better late then never so :
I've been able to determine that the whole issue came from my USB cable. Somehow there was an electrical issue in that cable and the computer-or the hokuyo- was not able to properly communicate through it. I think that the USB HUB was somehow able to correct theses electrical issues.
Anyway, problem solved !
I'm having a strange behaviour with the Bonjour service discovery on the iPad.
My code which probably is not the best yet, sometimes is not able to discover a bonjour service.
For this conclusion I had my Macbook open at my side with a little app called Bonjour explorer, and a small app on a Windows XP PC which is a Bonjour service.
First I had to struggle with Windows XP side, which also seems an enemy for Bonjour services. But when it was getting discovered all the time by the Macbook app, the same was not happening on the iPad side.
My question is:
Is there any recommend way of establishing a connection with a Bonjour service using the iOS API?
