Did you read the chip data sheet? That will tell what you need to program the device. I don't think it will work with a bluetooth signal from your HC-05.
Here are some data sheets on this. By the way the programming data is I2C not serial data. Also baud rate it 115200 not 9600 as the HC-05 is set for.
PSoC 4 device on-board CY8CKIT-049 includes a UART bootloader for programming through the USB-Serial (USB-UART configuration) controller in the kit. Bootloader Host software tool that installs with PSoC Creator is used to bootload the device through the USB-UART interface.So you are actually bootloading the device. I think the challenge here will be creating a host application with a bluetooth layer which does the bootloader host functionality.
You may follow the appnote AN68272 (http://www.cypress.com/documentation/application-notes/an68272-psoc-3-psoc-4-psoc-5lp-and-psoc-analog-coprocessor-uart). In section 2.4 of the pdf, there is an opensource application for bootloading using PC Host.The application is UART based. You may have to create a bluetooth layer to this application to send the serial data over the bluetooth channel. As writing target flash is done row by row from host, atmost care must be taken. Hope this helps.
