while playing around with the OTAU stuff I saw that the OTAU Client Cluster sends a wrong ZCL Header in the ZCL Read Attributes Response
The direction field is set to server_to_client but it should be client_to_server.
Maybe there is a typo in the OTAU implementation? This is the first client cluster with attributes which I readed. Reading attributes from server clusters work fine - so maybe this relates to client clusters in general?
