MDM9205 - qapi_UART

I use a UART link on MDM9205 to communicate with a microcontroller.

I call qapi_UART_Open and qapi_UART_Receive functions to initiate the communication. All work fine ! :)

The ISR is called when I send a message.

Now, I want to be able to receive a continuous flow of data. In this case, I want to know when ISR is called.

In the documentation, it is written : "rx_cb_isr is called when RX transfer completion."

But, what is the definition of "transfer completion" ?

Thanks for your help !
