I have to develop an application which requires Bluetooth and profile change functionality for Symbian phones. After spending sometime I found that following options:
1. Java: but java does not allow to change profile
2. Symbian C++: I read basics for Symbian C++ and created some basic stuffs. Symbian extended APIs provide simple APIs for Profile and Bluetooth (I haven't tested yet). But its required lot of efforts to grab these. Specially certificate singing problem. I want to test my application on different devices and wish to give my friends whom having different cellphones. But couldn't due to signing problem.
3. QT: I am still confused on this. Whether this platform capable to fulfill my requirement or not. Secondly which phone supports QT or not...
Honestly, I am bit frustrated while writing this. I am looking someone, experience in these matter, to guide me in this situation.
