Abstract

Claims (53)

1. A method of wirelessly interfacing with a trainable transceiver located in a vehicle, comprising:

entering into one of a plurality of modes;

interfacing with a remote device in a bidirectional communication using one of the plurality of modes;

transmitting packets from the trainable transceiver to the remote device;

transmitting packets including a request command from the remote device to the trainable transceiver;

determining whether the packet received by the trainable transceiver from the remote device is valid;

upon determining the packet received by the trainable transceiver is invalid, and a predetermined period of time has elapsed, entering into train mode;

upon determining the packet received by the trainable transceiver is valid, determining whether the request command from the remote device is valid and:

upon determining that the request command is invalid, entering into train mode,

upon determining that the request command is valid, entering into the train mode when the request command is for normal operation, and entering into a wireless diagnostic mode when the request command is for diagnostic mode;

transmitting a response command from the trainable transceiver to the remote device based on the requested command; and

receiving one of a plurality of inputs on the trainable transceiver to enter into one of the plurality of modes.

2. The method of claim 1 , further comprising:

receiving a sequence of a plurality of inputs on the trainable transceiver; determining whether the sequence is valid;

if the sequence is invalid, entering into a normal operation mode: and if the sequence is valid;

receiving a request command from the remote device at the trainable transceiver, and

transmitting a response command to the remote device from the trainable transceiver based on the request command.

3. The method of claim 2 , further comprising: determining whether the packet received by the trainable transceiver from the remote device has been received;

if the packet received by the trainable transceiver from the remote device has been received and is valid, determining which one of the plurality of modes has been requested by the request command;

if the request command is for diagnostics, sending a response command to the remote device to set a flag to enter into wireless diagnostic mode, and entering into the wireless diagnostic mode; and

if the request command is for flash, sending a response command to the remote device and entering into a wireless flash mode.

4. The method of claim 3 , further comprising:

if the packet 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.

5. The method of claim 1 , wherein the plurality of modes includes one of a wireless diagnostic mode, a wireless flash mode and a wireless vehicle interface mode.

6. The method of claim 5 , wherein each of the plurality of modes is an executable program product stored in memory of the trainable transceiver and executable by a microcontroller.

7. A trainable transceiver unit for a vehicle comprising:

a microcontroller;

a memory in communication with said microcontroller; and

a wireless bidirectional interface mode stored in said memory and having executable instructions configured to establish wireless bi-directional communication between said transceiver unit and at least one remote device,

wherein wireless bi-directional communication between said transceiver and at least one remote device includes transmitting a packet from the trainable transceiver to the at least one remote device, wherein wireless bi-directional communication between said transceiver and at least one remote device further includes transmitting a packet, including a request command, from the at least one remote device to the trainable transceiver, wherein the trainable transceiver enters one of a plurality of modes in response to the request command, and wherein the trainable transceiver is further configured to:

determine whether the packet received by the trainable transceiver from the remote device is valid;

enter into train mode in response to determining the packet received by the trainable transceiver is invalid, and after a predetermined period of time has elapsed;

in response to determining the packet received by the trainable transceiver is valid, determine whether the request command from the remote device is valid and:

enter into train mode in response to determining that the request command is invalid; and

in response to determining that the request command is valid, enter into the train mode when the request command is for normal operation, and enter into a wireless diagnostic mode when the request command is for diagnostic mode; and

wherein the trainable transceiver is further configured to enter into one of the plurality of modes in response to receiving one of a plurality of inputs at the trainable transceiver.

8. A trainable transceiver unit as set forth in claim 7 further comprising: a wireless transceiver; and said wireless bidirectional interface mode including an automatic scan mode having executable instructions configured to initiate a continuous scan for the at least one remote device using the wireless transceiver.

9. A trainable transceiver unit as set forth in claim 7 further comprising:
