message name
Message body: { "state":0, "ip": xxxx } 0: preparation completion, 1: is not ready for use
In an embodiment of the present invention, after receiving the preparation of the host device plugin registration service state, the slave device notifies the host device of the externally provided capability of the device by way of a command, and after receiving the failure message, the slave device needs to have a retry mechanism.
Specific message formats are exemplified as follows, wherein uuid represents a function unique identifier.
Device registration
1) Command name:
2) message body:
3) and returning a result: 0 { "state":0} 0: success, 1: failure of
In an embodiment of the present invention, the set of sub-functions supported by the query is implemented, and it is mainly the main device that obtains the sub-functions supported by the uuid from the device according to the uuid.
The function unique identifier and the sub-function name are combined into a unique message or command name, and specific message formats are as follows:
the format is as follows:
UUID@
command name:
message body:
{
"uuid":"uuid"
}
and returning a result:
