Operating method for integrated interface of PDA and wireless communication system
First Claim
1. An operating method for a device having a PDA and a wireless communication system integrated into a whole in the device, comprising:
- transmitting a wake-up signal from the wireless communication system to the PDA when the wireless communication system starts to operate from a standby mode;
waking the PDA up from a sleep state when the wake-up signal is received by the PDA;
receiving an electromagnetic wave signal by a wireless communication element;
converting the electromagnetic wave signal into an audio data;
transmitting the audio data from the wireless communication system to an audio element inside the PDA via a serial port connected between the wireless communication system and the PDA;
outputting the audio data by the audio element; and
when the PDA is turned on, performing the steps;
turning on the PDA;
turning on the wireless communication system by the PDA; and
resetting the wireless communication system after turning on the wireless communication system.

Abstract
An operating method for an integrated interface of a PDA and a wireless communication system includes the following steps. Firstly, when the wireless communication system starts to operate from a standby mode, a state signal is transmitted from the wireless communication system to the PDA. Then, if the PDA receives the state signal when the PDA is in a sleep state, the PDA is wakened and an input source of an audio element inside the PDA is switched to the wireless communication system. An electromagnetic wave signal is received by a wireless communication element and converted into audio data. Afterwards, the audio data is transmitted from the wireless communication system to the PDA and outputted by the audio element.

16. A device comprising:
-
a wireless communication system for receiving an electromagnetic wave signal and converting the electromagnetic wave signal into an audio data; a PDA having a processor and an audio element connected to the processor, wherein the wireless communication system and the PDA are integrated into a whole in the device; a serial port connected between the wireless communication system and the PDA, wherein the audio data is transmitted from the wireless communication system to the audio element of the PDA via the serial port and outputted by the audio element; a wake-up signal line connected between the PDA and the wireless communication system, wherein the wake-up signal line is used for transmitting a wake-up signal from the wireless communication system to the PDA to wake the PDA up from a sleep state when the wireless communication system starts to operate from a standby mode; and a PDA-turn-on-wireless-communication-system signal line connected between the wireless communication system and the PDA for transmitting a PDA-turn-on-wireless-communication-system signal from the PDA to the wireless communication system to turn on the wireless communication system. - View Dependent Claims (17, 18, 19, 20)
