Bluetooth Classic with iOS ExternalAccessoryFramework
I'm looking at development of an iOS app that will communicate with Bluetooth classic devices using iOS Supported Bluetooth Profiles As I understand, this should be possible using the External Accessory framework and should not require participation in the MFi program. From the MFi FAQ: What types of accessories and technologies are not part of the MFi Program? Accessories that do not use any of t

android ad-hoc udp broadcast hangs on send(ndk)
I'm trying to send a broadcast message in my ad-hoc network - 192.168.2.x, using native c code. But the app hangs on sendto(). btw the hang is not connected to the while, that wraps it, as I can see in debug, it only tries sendto() ones and hangs.

Why can't code inside unit tests find bundle resources?
Some code I am unit testing needs to load a resource file. It contains the following line: NSString *path = [[NSBundle mainBundle] pathForResource:@"foo" ofType:@"txt"]; In the app it runs just fine, but when run by the unit testing framework pathForResource: returns nil, meaning it could not locate foo.txt. I've made sure that foo.txt is included in the Copy Bundle Resources build phase of the un
How to programmatically force bluetooth low energy service discovery on Android without using cache

However Android only queries the peripheral once to discover services, subsequent calls to discoverServices() result in the cached data from the first call, even between disconnections. If I disable/enable the Android bt
What is the iBeacon Bluetooth Profile
I'd like to create my own iBeacon with some Bluetooth Low Energy dev kits. Apple has yet to release a specification for iBeacons, however, a few hardware developers have reverse Engineered the iBeacon from the AirLocate Sample code and started selling iBeacon dev kits. So what is the iBeacon Bluetooth Profile? Bluetooth Low Energy uses GATT for LE profile service discovery. So I think we need to k
How do I run Eclipse using Oracle's new 1.7 JDK for the Mac?
I'm trying to get the new 1.7 JDK working with Eclipse (this is Oracle's official release). I don't mean just pointing Eclipse to it so you can use it in projects, this works fine, but actually making Eclipse run using the 1.7 JVM. I've moved the new JVM to the top of the list in Java Preferences, but Eclipse still starts with 1.6. If I disable 1.6 in Java Preferences I get a dialog immediately af
Display local UIImage on UIWebview
You have a couple of options. You can load the page with a baseURL of [[NSBundle mainBundle] bundleURL] or you can use javascript to set the path to your image using the following method. [[NSBundle mainBundle] URLForResource:@"myimage" withExtension:@"png"] Edit: Check here Link to resources inside WebView - iPhone. It looks like you will use pathForResource rather than URLForResource. Edit 2: Yo
