On the portable (and portableNative) examples, the UART_read in the console thread returns 0 on the first read after a power cycle. The example currently takes this as an error and closes the UART.

A simple work-around is to either:

1. Delay the first UART_read until the UART is stabilized after the power cycle. We've found the following enough of a delay.

** for (i = 0; i < 100000; i++)

{ }
2. Don't treat the zero return as an error. Instead simply call UART_read again.

UART_read returns 0 in portable after a power-cycle on CC13x0 and CC26x0 devices
