Hello, everyone, I want to ask: How to transfer the USB signal from CP2102 to the bluetooth module and communicate with the bluetooth module?
Thanks in advance.
This is called an "XY problem". I think you need to tell us what it is you are trying to do and why?
And you have not specified what Bluetooth module this may be.
The first thing is to take care of the voltage differences between the two.
The second is to realize there is no "signal", there are data messages on the USB that will be transferred to the serial output put pin if the data message is identified by the chip as being "serial data". When the voltage differences are resolved, the serial data can be connected to the serial input of the Bluetooth module.
Same thing applies for data going the other way.
