Configuration mode entry for a tire monitoring device
Restricting commands for a tire monitoring device including controlling entry into a configuration mode and restricting operation based on detection of an abnormal command pattern. The method includes, at a tire monitoring device: receiving a configuration request from a first device for the tire monitoring device to operate in a configuration mode, the configuration request provided using a first wireless communication protocol; responsive to receipt of the configuration request, initiating communication using a second wireless communication protocol; establishing successful communication using the second wireless protocol; and entering the configuration mode responsive to establishing successful communication using the second wireless communication protocol. In another example, a method restricts operation of a tire monitoring device including receiving instructions via a wireless communication interface; detecting an abnormal instruction pattern based on the received instructions; and restricting the operation of the tire monitoring device responsive to detecting the abnormal instruction pattern.
1. A method comprising at a tire monitoring device:
receiving a configuration request from a first device, the configuration request indicating that the tire monitoring device is to operate in a configuration mode, the configuration request provided using a first wireless communication protocol;
responsive to receipt of the configuration request, initiating a communication using a second wireless communication protocol;
establishing successfully the communication using the second wireless protocol;
entering the configuration mode responsive to the establishing successfully the communication using the second wireless communication protocol, and
rejecting a configuration request when received via the second wireless communication protocol.
2. The method of claim 1 , wherein, in the configuration mode, the tire monitoring device receives at least one of configuration data and configuration instructions from the first device using the first wireless communication protocol.
3. The method of claim 2 , wherein the configuration instructions comprise at least one of: a data download instruction; a tire monitoring device test instruction; a system test instruction; a fault reset instruction; and a delete instruction.
4. The method of claim 2 , wherein, in the configuration mode, communication with the first device using the first wireless communication protocol is controlled by the tire monitoring device.
5. The method of claim 1 , further comprising determining that the first device is trusted and the entering the configuration mode is responsive both the determination that the first device is trusted and the establishing successful the communication using the second wireless communication protocol.
6. The method of claim 1 , wherein the communication using the second wireless protocol is with a second device, different from the first device.
7. The method of claim 1 , wherein the tire monitoring device remains in the configuration mode for a predetermined time period after entering the configuration mode.
8. The method of claim 1 , wherein the first wireless communication protocol has a larger range than the second wireless communication protocol.
9. The method of claim 1 , wherein the first wireless communication protocol has a range of more than 20 m and the second wireless communication protocol has a range of less than 10 centimeters.
10. A tire monitoring device comprising:
a wireless communication interface; and
a processing system configured to cause the tire monitoring device to execute the method of claim 1 .
11. A tire monitoring device according to claim 10 , wherein the wireless communication interface comprises:
a first transceiver for communication using the first wireless communication protocol; and
a second transceiver for communication using the second wireless communication protocol.
12. A tire monitoring system, comprising:
a tire monitoring device according to claim 10 ; and;
a first device arranged to send at least a configuration request to the tire monitoring device.
13. A computer-readable medium comprising computer-readable instructions that when executed by a processor, cause a tire monitoring device to execute the method of claim 1 .
14. A tire monitoring device configured to be mounted on a wheel of a vehicle, the tire monitoring device comprising:
a first wireless communication interface;
a second wireless communication interface; and
a processing system configured to enter the tire monitoring device into a configuration mode by:
receiving a configuration request using the first wireless communication interface;
responsive to receipt of the configuration request, initiating a communication using the second wireless communication interface;
establishing successfully the communication using the second wireless communication interface;
entering a configuration mode responsive to the establishing successfully the communication using the second wireless communication interface, and
rejecting a configuration request when received via the second wireless communication protocol.
