I have implemented a application to check whether bluetooth is ON/OFF using CoreBluetooth.framework but when i run that application on my iphone 3GS device it shows that the device does not support bluetooth low energy. please anybody help me with this or just a hint about any other bluetooth APIs that supports for iphone 3GS also appreciable.
Thanks
CoreBluetooth framework is only available in iOS 5.0+ and the hardware for Bluetooth 4.0 is only currently included in the iPhone 4S, iPhone 5 and the new iPad. Your 3GS does not have the necessary hardware to support the CoreBluetooth framework calls which is why you get the message you get.
I don't know if you want to use private API on your app, but in case you can the BluetoothManager is a simple API and can do what you need...
Here is a link that can help you.
Other than that it's not possible using public API so far...
Core Bluetooth only works on BLE module (Bluetooth 4.0). iPhone 3GS was released in 2009 while BLE standard was released in 2011. Even though iPhone 3GS could run iOS 6.0, it still cannot work with CoreBluetooth.

To silence my game when returning to the menu, I call this code:
alListenerf( AL_GAIN, gain );
This works just fine on Linux: the game goes silent.
When I run on iPad PRO, the sounds are still played, and volume is not affected at all.
Is AL_GAIN optionally implemented in the spec or something?
Using OpenAL device 'Default Audio Device'
Using ALUT 1.1
AL_VENDOR Apple Inc.
AL_RENDERER Software
AL_VERSION 1.1
This is on the latest iPad PRO model, by the way.
Whoa! the plot thickens... setting gain on iPhone6 works, on iPad PRO it does not. The same binary.
It is probably an iOS version thing. The iPad is on iOS 11.4 and the phone is on iOS 10.3.3
in linux and other platforms setting the volume to 0 works but for the ios13 bug as in the iPad pro change the volume to 0.001f and it should bypass Apple's bug.
I am planning to develop an iOS application where I need to use VOIP services. I found Liblinphone which is one such open source API for VOIP.
My requirements:
Making voice call & receiving
Making video calls & receiving
Making voice call conferences.
Are these all possible with Liblinphone? Are there any other opensource VOIP libraries for achieving this better than Liblinphone?
Any help and tutorial links are a big helpfor me.
You may take a look at siphon (http://code.google.com/p/siphon/).
From their homepage:
Home of the World's first free SIP/VoIP application for iPhone and iPod Touch 1 and 2.
Siphon SIP/VoIP project is the first in his category that works on iPhone and iPod Touch 2 with headset for all SIP providers. It is a native application approved running on 2.X using internal micro/speaker and headset.
The Application supports the SIP standard, preserving compatibility with hundreds of SIP providers and offers a GUI which preserves the apple design of native iPhone applications.
I am developing a mobile app using j2me. It works fine in "sony ericsson z530i". It works fine in "Nokia c2-00" mobile before 1 week. But I run the app now in nokia phone after sometime in the middle of app automatically my nokia phone switches off. I cannot resolve it but it works fine in sony ericsson mobile. I think I need to change some phone setting or the phone is in problem? I cannot find a solution so please help me solve the issue. I am using "Nokia c2-00" mobile which had "S40" sdk.
Some time problem may be in MIDP version in the mobile application check whether property and select MIDP as 2.0.
I find the solution.The problem is not in mobiles is in my application.It will not run due to ran out of heap memory.
Now i modified my code with respect to decrease the memory leak.Now its working in all mobiles which have the configuration cldc1.1 and midp2.0
I developed the game in j2me. I need emulator for screen 240x400 touch and 360x640 touch. Where should i get ?
Download any of the manufacturers custom SDKs (SonyEricsson, Nokia, LG, Motorola )and find a device with your resolution
PS: It may be difficult as many of them moved to Android or other technologies
I'm currently involved in a research project that requires me to access a Windows Mobile Camera and sound recorder with J2ME to, well take pictures and record sound... the phone has to be a windows mobile for some reason that has nothing to do with me and the software has to be written in Java, also not my decision.
So I need to try and find a phone that supports this (if one exists) so I'd like to know if anyone has found one?
Thank You For Your Help.
(Note the phone supporting MMAPI (JSR 135) does not imply that you can use the camera and sound recorder, our current phone has this and has not access).
First, if you have any Windows Mobile 6.x device, please try to use JVM build for Windows Mobile from Sun Microsystems => http://blogs.oracle.com/javamesdk/entry/jvm_for_windows_mobile
Or, you can buy LG Monaco (WM 6.5) from AT&T network. It has Java ME with MMAPI camera support. Also, LG Incite (WM 6.1) have MMAPI camera support.
As I know, recent HTC WM device with Java ME also support MMAPI camera features.
Good luck.
