CC2538 usb cdc and custom PC app communication.



hai ,

My Aim : to have a custom app communicate with cc2538 over the usb ( something like updating firmware ).

I was able to configure the cc2538 to detect as usb cdc device in PC. But now am stuck because i need to know how the cc2538 can process my data from the PC app.
In the Z mesh project i have tested this with Z tool . The Z tool commands are processed using MT_ProcessEvent task handler .

Is there any other feasible option or should i create a task handler for my commands ?

Can i monitor (while debugging) what are the incoming messages from my app/ or from a serial terminal  ? 

for example i want to echo whatever message has been typed from the serial port  back to the terminal using HalUARTWrite. 


Any help is appreciated .
thanks in advance.
