Could you please show a block diagram showing the interfaces you wish to connect? Please note that there are no examples currently on this for CYPD3120.
Yes, I checked the datasheet and it should be possible to connect the HC-05 bluetooth module over the UART interface. You could add a SCB configured with the required parameters for the UART interface and assign the appropriate pins in the CCG3 firmware.
For example, you could add the following code in main()-
UART_UartPutString("In main function\t\n");
For more information on the UART APIs, please refer to the SCB component datasheet in PSoC Creator.
Thank you, for your quick feedback.
