TestEventTrigger
This command SHALL be supported to provide a means for certification tests to trigger some test-plan-specific events, necessary to assist in automation of device interactions for some certification test cases.
|
client→server |
EnableKey: octet_string, EventTrigger: int64u |
| 0x01 |
TimeSnapshot
Provisional
This command MAY be used by a client to obtain a correlated view of both System Time, and, if currently synchronized and supported, "wall clock time" of the server.
|
client→server | None |
| 0x02 |
TimeSnapshotResponse
Provisional
This command SHALL be generated in response to a TimeSnapshot command.
|
server→client |
SystemTimeMs: systime_ms, PosixTimeMs: posix_ms |
| 0x03 |
PayloadTestRequest
Optional This command provides a means for certification tests or manufacturer's internal tests to validate particular command handling and encoding constraints by generating a response of a given size.
|
client→server |
EnableKey: octet_string, Value: int8u, Count: int16u |
| 0x04 |
PayloadTestResponse
Optional This command is sent by the server on receipt of the PayloadTestRequest command.
|
server→client |
Payload: long_octet_string |
