I have modified the dongle firmware to implement UART-BLE bridge project.
How to change dongle firmware to default?
The defalut dongle firmware and hex file are located at "C:\Program Files (x86)\Cypress\CY8CKIT-042-BLE Kit\1.0\Firmware\BLE Dongle" (or a similar location)
You can program this into the dongle using PSoC Programmer tool.

Thanks Madhu for the info.
I am able to program default firmware onto dongle.
