I would like to use this Firefox OS device as WiFi hotspot (with a Mac).
I have noticed some slowness. Does anyone know if that might be due to the WiFi receiver/emitter in the ZTE Open being a low quality component?
Is there any software (Mac preferred) that might enable me to tell where does the low performance come from (connection to the network -speed/latency-, wifi hotspot data exchange)?
Interesting question. One thing you could test on the device itself with JavaScript, is the connection speed and if it's metered. Hardware could potentially come into play here as well.

I updated iOS on my phone to 8.3 and I saw this message popup on first boot, but I have not seen it since:
I have been searching all day for information and I can't find a single reference to this message or to Xcode supporting wifi debug.
I am using a macbook pro 2009 model, and I have read that this is not compatible with the new continuity features (as well as airdrop etc). I am wondering if this is part of the wifi debug (and also if BTLE is involved at all). Of course it is all speculation since I cannot find any documentation about this.
Has anybody used wifi debug, or can point me to any documentation?
No, the feature was disabled as it causes serious security flows, for example when debugging you can fake location for any app, access confidential data like your number, udid etc. WiFi can be used now only to sync using iTunes.
It's restricted to USB only. You would need to write a bridge between USB and WiFi. You could in theory connect iPhone to Raspberry Pi, use open source crossplatform libMobileDevice. And mirror all USB requests from your XCode to this device USB.
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'm working on an application that does does lots of iOS <--> OSX communication. For the most part I have this solved.
I'm using CocoaPort to do the communication. Over Wifi this worked nicely and was plenty fast.
I'm using Bonjour to find my server. This required publishing the service with a modded DNSSDObjects-style net service on iOS. Apparently services published over Bluetooth on OSX cannot be seen by iOS, but the other way round works nicely, except that you need to keep the devices paired and connected.
Now my question is, how can I improve the speed of the Bluetooth connection? I'm getting maybe 100kb/s max and that seems to just stop after about 1 minute even though the connection is still open.
I think I need to use the AMP/HS stuff in Bluetooth 3.0 to get a fast connection. My understanding is this creates an AdHoc wireless network between my devices (MBP retina and iPad3, so should be capable of a decent speed.)
According to Wiki, Bluetooth 4.0 includes the HS spec in Bluetooth 3.0 and according to Bluetooth Explorer, the iPad is 4.0 spec. Is there a way, maybe via IOBluetooth, to request a high speed connection?
According to an engineer # Apple, this is not currently feasible. The best you can do is Bluetooth Classic, which is probably the speed I'm getting.
If you want this feature, consider opening a feature request at bugreporter.apple.com.
I have an iPad that worked perfectly with my iPads with WiFi only environment. But It was rejected due to one of the function that I suspected that the cellular network has something to do with it. Currently, without the necessary resources to test in that environment, I want to target this app only for WiFi version of iPad. Does anyone know if we can submit a WiFi only version app for iPad?
Of course it's not possible, and it's not really reasonable. As a developer you want to have as large userbase as possible, so targeting only wifi iPad version would not serve you at all. Just test it thorougly on different device configurations, fix the bugs and submit again. If you have Mac OS X Lion, you could use Network Link Conditioner Utility for simulating lousy internet connection (3G/Edge). Don't underestimate the importance of testing on the real device though.
I am working on a Mac that has an Ethernet connection to a LAN and the Internet. I have an iOS application that I am running in the simulator that needs to connect to a WiFi network in another office. I turned on Airport and connected to the WiFi network I need, but I don't know if the simulator is using the Ethernet or Wifi connection to communicate. I looked for settings in the simulator and couldn't find a way to tell it to use the WiFi connection exclusively.
Thanks for your help.
A coworker answered this question for me today. Apparently, the iOS simulator does not do WiFi. It only knows about a network connection. He said the simulator simply reports that there's a connection, but it's not WiFi.
Hope this helps someone.
I guess iOS Simulator uses whatever network connection is available tot the Computer it is running on. If there are multiple Connections it should scan both IP ranges... I don't exactly know how it handles the case both ip ranges are the same... This is (even if possible) no good solution, because you never exactly know if there are multiple devices with the same IP...
