CPC H04L 12/40 (2013.01) [H04L 41/0803 (2013.01); H04L 2012/40215 (2013.01)] | 20 Claims |
1. A method, comprising:
detecting, by a router of a controller area network (CAN) monitoring device comprising a processor, during an arbitration phase, a first CAN XL transceiver mode switch message being sent over a first receive data signal to a first transceiver of the CAN monitoring device, wherein the first CAN XL transceiver mode switch message is associated with a first CAN XL frame sent from a first CAN XL node on a CAN XL network to the first transceiver, wherein the CAN monitoring device further comprises a group of transceivers respectively coupled to different CAN XL nodes of a group of CAN XL nodes comprising the first CAN XL node, wherein the group of transceivers comprise the first transceiver, and wherein the first CAN XL transceiver mode switch message causes the first transceiver to switch from an asymmetric arbitration mode to a symmetric data receive mode; and
in response to the detecting, sending, by the router of the CAN monitoring device, a second CAN XL transceiver mode switch message over a second receive data signal to a second transceiver of the group of transceivers of the CAN monitoring device, wherein the second CAN XL transceiver mode switch message causes the second transceiver to switch from the asymmetric arbitration mode to a symmetric data transmit mode.
