Hello Community,I'm using an STM32G474RE MCU with FDCAN0 to set up CANopen communication for a sensor node device. The setup is designed to cascade multiple sensor devices on the same CAN bus, each with a unique node ID, so they can transmit data ind...

Hello everyone,I'm currently working with the STM32G474RE MCU and using a CANopen stack. I'm facing an issue where the Auto Bus-Off recovery isn't happening as expected.When there's a fault on the CAN bus, it correctly transitions to the warning stat...

Hi @SofLit , @Andrew Neil Thanks for the patience.Answers to your questionsAns : 1- The shared schematic is for a single node. I am connecting two identical nodes in parallel, and both have 120Ω termination resistors. I also tested the configuratio...

@SofLit ,Yes, I am testing with two CAN nodes, both sensor nodes, and no CAN analyzer is connected to the bus. It is only in this setup that I am encountering the issue.However, when I connect a CAN analyzer as one of the nodes, along with the sensor...

Hi @Andrew Neil ,Thank you for your response.On one of the nodes, the behavior is as expected. When no device is connected, it remains in Passive mode. However, when a CAN analyzer or master is connected, the node transitions to Active mode.

Hi @SofLit, Thank you for the reply.I followed your suggestion and set up a simple CAN communication project with two nodes, bypassing CANopen, Unfortunately, I’m still encountering the same issue. Both nodes are entering Error Passive mode, and the ...
