Method for waking a device in response to a wireless network activity
First Claim
1. A method for receiving information comprising:
- at a second electronic device, receiving a communication signal including a connection request transmitted from a first electronic device using a wireless communication protocol, said second electronic device comprising a processor, and a wireless communication device and wherein said processor is in a sleep mode while said wireless communication device is awake;
receiving said communication signal including said connection request from said first device;
determining whether a communication port is closed;
responsive to said connection request, if said communication port is closed, automatically triggering an interrupt to wake up the processor;
opening said communication port coupled to said wireless communication device for said processor to receive said communication signal; and
storing said communication signal.

Abstract
A method and a system for data transmission between a first electronic device and a second electronic device, wherein the second electronic device is in a sleep mode. Transmission of data between the first electronic device and the second electronic device occurs while a microprocessor in the second device is in sleep mode and the wireless transceiver is in a wake mode. The first electronic device transmits data signals and the second electronic device detects the transmitted signal. A base band processor in the second electronic device optionally determines if the signal is from a known source. If the first electronic device is a known electronic device, an interrupt signal is generated to wake up the microprocessor in the second electronic device. The wakened microprocessor opens a communication port and disables the wake-up interrupt. In yet another embodiment of the present invention, the data receive line is directly coupled to a line that triggers an interrupt when a signal is detected. The received message is then stored in memory for subsequent use.
