Expand description

Host Power State ** Format: ’C`

  • Describes the current power state of the host. This property is used
  • by the host to inform the NCP when it has changed power states. The
  • NCP can then use this state to determine which properties need
  • asynchronous updates. Enumeration spinel_host_power_state_t defines
  • the valid values (SPINEL_HOST_POWER_STATE_*):
  • HOST_POWER_STATE_OFFLINE: Host is physically powered off and
  • cannot be woken by the NCP. All asynchronous commands are
  • squelched.
  • HOST_POWER_STATE_DEEP_SLEEP: The host is in a low power state
  • where it can be woken by the NCP but will potentially require more
  • than two seconds to become fully responsive. The NCP MUST
  • avoid sending unnecessary property updates, such as child table
  • updates or non-critical messages on the debug stream. If the NCP
  • needs to wake the host for traffic, the NCP MUST first take
  • action to wake the host. Once the NCP signals to the host that it
  • should wake up, the NCP MUST wait for some activity from the
  • host (indicating that it is fully awake) before sending frames.
  • HOST_POWER_STATE_RESERVED: This value MUST NOT be set by the host. If
  • received by the NCP, the NCP SHOULD consider this as a synonym
  • of HOST_POWER_STATE_DEEP_SLEEP.
  • HOST_POWER_STATE_LOW_POWER: The host is in a low power state
  • where it can be immediately woken by the NCP. The NCP SHOULD
  • avoid sending unnecessary property updates, such as child table
  • updates or non-critical messages on the debug stream.
  • HOST_POWER_STATE_ONLINE: The host is awake and responsive. No
  • special filtering is performed by the NCP on asynchronous updates.
  • All other values are RESERVED. They MUST NOT be set by the
  • host. If received by the NCP, the NCP SHOULD consider the value as
  • a synonym of HOST_POWER_STATE_LOW_POWER.
  • After setting this power state, any further commands from the host to
  • the NCP will cause HOST_POWER_STATE to automatically revert to
  • HOST_POWER_STATE_ONLINE.
  • When the host is entering a low-power state, it should wait for the
  • response from the NCP acknowledging the command (with CMD_VALUE_IS).
  • Once that acknowledgment is received the host may enter the low-power
  • state.
  • If the NCP has the CAP_UNSOL_UPDATE_FILTER capability, any unsolicited
  • property updates masked by PROP_UNSOL_UPDATE_FILTER should be honored
  • while the host indicates it is in a low-power state. After resuming to the
  • HOST_POWER_STATE_ONLINE state, the value of PROP_UNSOL_UPDATE_FILTER
  • MUST be unchanged from the value assigned prior to the host indicating
  • it was entering a low-power state.
