Abstract

The invention relates to a universal wireless trainable transceiver unit with integrated bidirectional wireless interface functionality, and a method for same. Using a scan, push button or untrained channel mode, a user may enter into a wireless bidirectional interface mode of a trainable transceiver. The interface mode allows a user to select a sub-set of modes that include diagnostics, flash and vehicle interface. Each mode provides the trainable transceiver to communicate wirelessly in a bidirectional manner with another remote device.

if a packet including the request command transmitted from the remote device to the trainable transceiver has not been received by the trainable transceiver, and a predetermined amount of time has elapsed, entering into normal operation mode;

if the packet transmitted from the remote device to the trainable transceiver has been received by the trainable transceiver, determining whether the received packet transmitted from the remote device to the trainable transceiver is valid; and

if the received packet transmitted from the remote device to the trainable transceiver is invalid, entering into normal operation mode.

8. The method of claim 1, further comprising:

receiving one of a plurality of inputs on the trainable transceiver to enter into one of the plurality of modes of operation; and

exiting a current mode of operation and entering a new mode of operation based on the one or a plurality of inputs.

9. A method of wireless communication and interfacing between a trainable transceiver located in a vehicle and a remote device, comprising:
