Hi,
asuming you are using the uart in "async" mode, you should get an offset in the callback in evt->data.rx.offset

The following is the evt->data.rx structure

/**
 * @brief UART RX event data.
 *
 * The data represented by the event is stored in rx.buf[rx.offset] to
 * rx.buf[rx.offset+rx.len].  That is, the length is relative to the offset.
 */
struct uart_event_rx {
	/** @brief Pointer to current buffer. */
	uint8_t *buf;
	/** @brief Currently received data offset in bytes. */
	size_t offset;
	/** @brief Number of new bytes received. */
	size_t len;
};

In case you are using "interrupt driven" mode, I cannot help you, as I have never used it. (I am not nordic staff btw, you should also wait for an aswer from them)
