Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a variable multiplexer for vehicle communication bus compatibility. A device includes a variable multiplexer that can be electronically configured to a desired pinout configuration to provide compatibility with multiple vehicles. For example, the variable multiplexer may be electronically configured based on a pinout configuration used by the vehicle to connect pins in the device to the corresponding pins on the data link connector that provide the same specified function. The device may therefore use a single standardized cable with vehicles using a variety of pinout configurations.

Alternatively, the software selectable terminator resistor may be disabled when the device is added as an intermediate node positioned between terminator resistors in the high-speed communication bus.

Abstract: A message transmission method and related devices are provided in the disclosure. The method includes the following. A first long range (LoRa) device creates a LoRa mesh group. Based on a peer-to-peer (P2P) communication requirement with a second LoRa device belonging to the LoRa mesh group, the first LoRa device switches to a P2P communication mode, transmits a mode switching instruction to the second LoRa device, and increases a transmission priority associated with a target message type to a predetermined transmission priority. The mode switching instruction is used to instruct the second LoRa device to switch to the P2P communication mode. The target message type is the type of a message that needs to be transmitted in P2P communication between the first LoRa device and the second LoRa device. The first LoRa device transmits a message of the target message type to the second LoRa device.
