LAUNCHXL-CC2650: OSAL READ TO UART

I add the following codes in red to test write/read snv and output to UART in simple_peripheral example. I works well on my LAUNCHXL-CC2650.

#include <ti/drivers/uart/UARTCC26XX.h>
#include <stdio.h>

UART_Handle uart;
UART_Params uartParams;
char echoPrompt[] = "\fEchoing characters:\r\n";

uint8 status_snv;
uint8 write_buffer[10];
uint8 read_buffer[10];

static void SimpleBLEPeripheral_taskFxn(UArg a0, UArg a1)
{
  // Initialize application
  SimpleBLEPeripheral_init();
  Util_startClock(&periodicClock);
  /* Create a UART with data processing off. */
  UART_Params_init(&uartParams);
  uartParams.writeDataMode = UART_DATA_BINARY;
  uartParams.readDataMode = UART_DATA_BINARY;
  uartParams.readReturnMode = UART_RETURN_FULL;
  uartParams.readEcho = UART_ECHO_OFF;
  uartParams.baudRate = 115200;
  uart = UART_open(Board_UART0, &uartParams);

  if (uart == NULL) {
      return;
  }

  UART_write(uart, echoPrompt, sizeof(echoPrompt));

  // Application main loop
  for (;;)
  {
    // Waits for a signal to the semaphore associated with the calling thread.
    // Note that the semaphore associated with a thread is signaled when a
    // message is queued to the message receive queue of the thread or when
    // ICall_signal() function is called onto the semaphore.
    ICall_Errno errno = ICall_wait(ICALL_TIMEOUT_FOREVER);

    if (errno == ICALL_ERRNO_SUCCESS)

          }
        }

        {
          ICall_freeMsg(pMsg);
        }
      }

      // If RTOS queue is not empty, process app message.
      while (!Queue_empty(appMsgQueue))
      {
        sbpEvt_t *pMsg = (sbpEvt_t *)Util_dequeueMsg(appMsgQueue);
        if (pMsg)
        {

          SimpleBLEPeripheral_processAppMsg(pMsg);

          // Free the space from the message.
          ICall_free(pMsg);
        }

    }
