How to support GetNodeInfo and GetDataTypeInfo on STM32?

[dpslwk (LWK)]

This is the same behaviour I was seeing until I applied the fix from kolos450 mentioned in this thread

Hi. I’ve got the same issue. There is a typo in the appendToEndOf method: target = head->equal_keys; should be target = target->equal_keys; The case happens when the driver is busy and all the frames produced from a single message are sent to a linked list.
