Subscribing to message type and src node ID

Applications & Usage LibCyphal

Hi!

In my application there are multiple nodes of same type, like multiple temperature sensors of the same type. Although they each has unique node id.

I am wondering if a node that subscribes to such message can “filter out” messages only from a particular node id? (without using CAN filters)

Or does the subscriber application need to collect all messages of that type and then ignore all node id:s not interesting?

Kind Regards

Yes, currently this is the only possible approach in UAVCAN v0. In the first stable release we’re currently working on (termed UAVCAN v1.0), the case you’re describing will be supported much better. Here is an overview: Stockholm Summit recap
