10.6. The Attribute Protocol

The client sends a request to the server to request that the server do something and send back a
response, as depicted in Figure 10–26. A client can send only one request at a time. This reduces the
complexity on the server, reducing the memory requirements, and thereby making it possible to
implement an attribute server using very little code. For each request, there can be only two possible
responses: a response that is directly associated with the request, or an error response that gives
information about why the request failed.

I want to know [atts_write_rsp_send] equivalent to the ATT response of " Figure 10–26. An Attribute Protocol request(Bluetooth Low Energy The Developer-'s Handbook)".
It is right??
