The problem is that i want to interface my mobile phone with my computer using a keypad in between. The interfacing should be done in Python environment as this would help me in my further work. the things which i need is
1.inteface my computer with the keypad using python 2. interface the same keypad with a mobile phone
so that i can control the general features of my mobile phone with that keypad using the python code.
The most general way to connect your computer to a phone would be over TCP/IP, likely delivered via WiFi to your phone. If using an Android, BlueTooth would be another option, but iOS will not connect to unapproved BT devices.
Programming on the handset will likely have to be done in the native language. It's an absolute requirement of iOS, and I'm not sure if you can use Python/Jython to build a full app on Android yet.
On the PC side, you could easily use Python, perhaps its socket module to talk with the handset over TCP/IP or pySerial's serial if you use BlueTooth RFCOMM/SPP; though managing the actual BT connection is very complex and very sensitive to drivers.
