Hi,

[quote user=""]1. How to connect this Bluetooth module with my android mobile device?[/quote]

Use a debugger to program it with a Bluetooth Low Energy (BLE) example from SDK 12.3 (which is the latest SDK with support for the nRF51 series).

[quote user=""]2. Is there any ready Firmware code to enable Bluetooth to uart communication?[/quote]

Yes, the UART/Serial Port Emulation over BLE example, which implements the Nordic UART Service (NUS).

[quote user=""]3. Is not what are the developing tools and software needed for this? [/quote]

SDK, Toolchain/IDE (for instance Keil) and a debugger (for instance using a nRF51 DK).

[quote user=""]4. How the data will send from the mobile app to this module?[/quote]

If you use the NUS example suggested above, you read or write to the respective characteristics for Rx and Tx to send/receive data. I suggest you start experimenting with nRF Connect app together with the example
