I have the following setup:
3 MTLT335D IMUs connected to a CAN bus with various other nodes on the CAN bus. I use Nav View to set the baud rate for the CAN bus to 500 Kbps and the address for the IMUs (132, 133 and 134). Once they are configured, I plug them into the CAN bus and power everything on.
The IMUs do not communicate on the CAN bus after everything is powered up. They do start communicating however when I send a CAN message requesting ECU ID from the IMUs. The CAN frame I send is:
CAN ID - 18EAFFF9 ; Length - 3 ; Data - 00 FD C5
As soon as I send this message, the IMUs start communicating and I see the sensor data messages on the CAN bus.
The strange part is that I have the same series IMUs on another setup and the IMUs in that setup start communicating as soon as they are plugged into the CAN bus without having to send a message requesting any kind of data from the IMUs.
Please advise on how to debug this issue.
