Description:
This response sends to the host when a successful association happens for
the agent identified by ‘hhhh’ (16 bit decimal number). For completeness,
the data specialization nominal code ‘iiii’ (16 bit decimal) and the device
configuration ID ‘cccc’ (16 bit decimal) that got negotiated with the
manager, is also provided. The 16 character parameter ‘ssssssss’ specifies
the system ID of the agent.
Note: An agent data specialization can be basic as specified in the
relevant spec, or more enhanced with more capabilities. For
example, with the weigh scale Laird provides for the basic MDS
collection, it is possible to specify multiple MDS collection which
expose more functionality (such as body mass index attributes).
These extended collections are identified by configuration IDs and
are offered to a manager during the association phase in
descending order of complexity until the manager accepts one that it
can work with.
Command:
No Command. This is a status message.
Response:
HDM:SCANPERIOD hhhh<more>
Description:
This response sends to the host when a scan report receives from agent
identified by handle ‘hhhh’. Since a scan report can consist of data values for
many attributes, this report is formatted with embedded <lf> characters as
follows:
<cr><lf>HDM:SCANREPORT hhhh:pppp
<lf>O:oooo
<lf>A:aaaa,ddd..ddd
<lf>A:aaaa,ddd..ddd
…
<lf>O:oooo
<lf>A:aaaa,ddd..ddd
<lf>A:aaaa,ddd..ddd
…
…
<cr><lf>
Where <lf>O: identifies the collection object (oooo == 1 for NU etc) and then
subsequence <lf>A: lines consist of value pairs aaaa,ddd.ddd where ‘aaaa’ is
the attribute nominal code and ddd...ddd is its value in hexadecimal. The size
of the value for each attribute is specified in the IEEE standards.
