The network save/recall feature is an optional NCP capability that, when present, allows the host to save and recall network credentials and state to and from nonvolatile storage.
The presence of the save/recall feature can be detected by checking for the presence of the CAP_NET_SAVE capability in PROP_CAPS.
Network clear feature allows host to erase all network credentials and state from non-volatile memory.
| Octets: | 1 | 1 |
|---|---|---|
| Fields: | HEADER | CMD_NET_SAVE |
Save network state command. Saves any current network credentials and state necessary to reconnect to the current network to non-volatile memory.
This operation affects non-volatile memory only. The current network information stored in volatile memory is unaffected.
The response to this command is always a CMD_PROP_VALUE_IS for PROP_LAST_STATUS, indicating the result of the operation.
This command is only available if the CAP_NET_SAVE capability is set.
| Octets: | 1 | 1 |

| Fields: | HEADER | CMD_NET_CLEAR |
Clear saved network settings command. Erases all network credentials and state from non-volatile memory. The erased settings include any data saved automatically by the network stack firmware and/or data saved by CMD_NET_SAVE operation.
This operation affects non-volatile memory only. The current network information stored in volatile memory is unaffected.
The response to this command is always a CMD_PROP_VALUE_IS for PROP_LAST_STATUS, indicating the result of the operation.
This command is always available independent of the value of CAP_NET_SAVE capability.
| Octets: | 1 | 1 |
|---|---|---|
| Fields: | HEADER | CMD_NET_RECALL |
Recall saved network state command. Recalls any previously saved network credentials and state previously stored by CMD_NET_SAVE from non-volatile memory.
This command will typically generated several unsolicited property updates as the network state is loaded. At the conclusion of loading, the authoritative response to this command is always a CMD_PROP_VALUE_IS for PROP_LAST_STATUS, indicating the result of the operation.
This command is only available if the CAP_NET_SAVE capability is set.
