## MAC Properties {#prop-mac}

### PROP 48: PROP_MAC_SCAN_STATE {#prop-mac-scan-state}
* Type: Read-Write
* Packed-Encoding: `C`
* Unit: Enumeration

Possible Values:

* 0: `SCAN_STATE_IDLE`
* 1: `SCAN_STATE_BEACON`
* 2: `SCAN_STATE_ENERGY`
* 3: `SCAN_STATE_DISCOVER`

Set to `SCAN_STATE_BEACON` to start an active scan.
Beacons will be emitted from `PROP_MAC_SCAN_BEACON`.

Set to `SCAN_STATE_ENERGY` to start an energy scan.
Channel energy result will be reported by emissions
of `PROP_MAC_ENERGY_SCAN_RESULT` (per channel).

Set to `SCAN_STATE_DISOVER` to start a Thread MLE discovery
scan operation. Discovery scan result will be emitted from
`PROP_MAC_SCAN_BEACON`.

Value switches to `SCAN_STATE_IDLE` when scan is complete.

### PROP 49: PROP_MAC_SCAN_MASK {#prop-mac-scan-mask}
* Type: Read-Write
* Packed-Encoding: `A(C)`
* Unit: List of channels to scan


### PROP 50: PROP_MAC_SCAN_PERIOD {#prop-mac-scan-period}

Octets: | 1  |   1  |    2    |   *n*    |    2    |   *n*
--------|----|------|---------|----------|---------|----------
Fields: | CH | RSSI | MAC_LEN | MAC_DATA | NET_LEN | NET_DATA

Scan beacons have two embedded structures which contain
information about the MAC layer and the NET layer. Their
format depends on the MAC and NET layer currently in use.
The format below is for an 802.15.4 MAC with Thread:

* `C`: Channel
* `c`: RSSI of the beacon
* `t`: MAC layer properties (802.15.4 layer shown below for convenience)
  * `E`: Long address
  * `S`: Short address
  * `S`: PAN-ID
  * `c`: LQI
* NET layer properties (Standard net layer shown below for convenience)
  * `i`: Protocol Number
  * `C`: Flags
  * `U`: Network Name
  * `d`: XPANID
  * `d`: Steering data

Extra parameters may be added to each of the structures
in the future, so care should be taken to read the length
that prepends each structure.

### PROP 52: PROP_MAC_15_4_LADDR {#prop-mac-15-4-laddr}
* Type: Read-Write
* Packed-Encoding: `E`

The 802.15.4 long address of this node.

This property is only present on NCPs which implement 802.15.4

### PROP 53: PROP_MAC_15_4_SADDR {#prop-mac-15-4-saddr}
* Type: Read-Write
* Packed-Encoding: `S`

The 802.15.4 short address of this node.

This property is only present on NCPs which implement 802.15.4

### PROP 54: PROP_MAC_15_4_PANID {#prop-mac-15-4-panid}
* Type: Read-Write
* Packed-Encoding: `S`

The 802.15.4 PANID this node is associated with.

This property is only present on NCPs which implement 802.15.4

### PROP 55: PROP_MAC_RAW_STREAM_ENABLED {#prop-mac-raw-stream-enabled}
* Type: Read-Write
* Packed-Encoding: `b`

Set to true to enable raw MAC frames to be emitted from `PROP_STREAM_RAW`.
See (#prop-stream-raw).

### PROP 56: PROP_MAC_PROMISCUOUS_MODE {#prop-mac-promiscuous-mode}
* Type: Read-Write
* Packed-Encoding: `C`

Possible Values:

Id | Name                          | Description
---|-------------------------------|------------------
 0 | `MAC_PROMISCUOUS_MODE_OFF`    | Normal MAC filtering is in place.
 1 | `MAC_PROMISCUOUS_MODE_NETWORK`| All MAC packets matching network are passed up the stack.
 2 | `MAC_PROMISCUOUS_MODE_FULL`   | All decoded MAC packets are passed up the stack.

See (#prop-stream-raw).

### PROP 57: PROP_MAC_ENERGY_SCAN_RESULT {#prop-mac-escan-result}
* Type: Read-Only-Stream
* Packed-Encoding: `Cc`

This property is emitted during energy scan operation
per scanned channel with following format:

* `C`: Channel
* `c`: RSSI (in dBm)

### PROP 58: PROP_MAC_DATA_POLL_PERIOD {#prop-mac-data-poll-period
* Type: Read-Write
* Packed-Encoding: `L`

The (user-specified) data poll (802.15.4 MAC Data Request) period
in milliseconds. Value zero means there is no user-specified
poll period, and the network stack determines the maximum period
based on the MLE Child Timeout.

If the value is non-zero, it specifies the maximum period between
data poll transmissions. Note that the network stack may send data
request transmissions more frequently when expecting a control-message
(e.g., when waiting for an MLE Child ID Response).

This property is only present on NCPs which implement 802.15.4.

### PROP 4864: PROP_MAC_WHITELIST  {#prop-mac-whitelist}
* Type: Read-Write
* Packed-Encoding: `A(T(Ec))`
* Required capability: `CAP_MAC_WHITELIST`

Structure Parameters:

* `E`: EUI64 address of node
* `c`: Optional RSSI-override value. The value 127 indicates
       that the RSSI-override feature is not enabled for this
       address. If this value is omitted when setting or
       inserting, it is assumed to be 127. This parameter is
       ignored when removing.

### PROP 4865: PROP_MAC_WHITELIST_ENABLED  {#prop-mac-whitelist-enabled}
* Type: Read-Write
* Packed-Encoding: `b`

### PROP 4867: SPINEL_PROP_MAC_SRC_MATCH_ENABLED  {#prop-mac-src-match-enabled}
* Type: Write
* Packed-Encoding: `b`

Set to true to enable radio source matching or false to disable it. This property
is only available if the `SPINEL_CAP_MAC_RAW` capability is present. The source match
functionality is used by radios when generating ACKs. The short and extended address
lists are used for settings the Frame Pending bit in the ACKs.

### PROP 4868: SPINEL_PROP_MAC_SRC_MATCH_SHORT_ADDRESSES  {#prop-mac-src-match-short-addresses}
* Type: Write
* Packed-Encoding: `A(S)`

Configures the list of short addresses used for source matching. This property
is only available if the `SPINEL_CAP_MAC_RAW` capability is present.

Structure Parameters:

* `S`: Short address for hardware generated ACKs

### PROP 4869: SPINEL_PROP_MAC_SRC_MATCH_EXTENDED_ADDRESSES  {#prop-mac-src-match-extended-addresses}
* Type: Write
* Packed-Encoding: `A(E)`

Configures the list of extended addresses used for source matching. This property
is only available if the `SPINEL_CAP_MAC_RAW` capability is present.

Structure Parameters:

* `E`: EUI64 address for hardware generated ACKs

### PROP 4870: PROP_MAC_BLACKLIST  {#prop-mac-blacklist}
* Type: Read-Write
* Packed-Encoding: `A(T(E))`
