Constant SPINEL_PROP_HOST_POWER_STATE

pub const SPINEL_PROP_HOST_POWER_STATE: _bindgen_ty_24 = 12;

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.
