When receiving multiples Bluetooth 5 Mesh acknowledged message, how could we figure out which node returns the ack message?

Hi,

If fires multiple generic_onoff_client set  LED = True command from PyACI libraries with Ack = True to multiple nodes, the generic_onoff_client will provide a "generic_on_off_status_handler" to handle the reply message from the nodes, but we don't know which node reply for this Ack message. 

Do we have a way to figure out which node returns the ack message?

Hi,

We do not recommend acknowledged messages to group addresses, as it increases network load and will only trigger retransmits if no acks are returned at all. If you do choose to use them anyway then you should be able to distinguish the replies by reading the source address of the reply messages.
