Capability codes advertised via PROP_CAPS.

Constants

ADMIN

CAP_ADMIN — the device can be managed over the mesh by the nodes listed in PROP_DEV_ADMINS. Requires CAP_DEV_IDENTITY, since an administrator addresses the device identity, and CAP_CMD_MULTI, so an administrator may rely on the multi-property commands.

ADVERT

CAP_ADVERT — the device announces itself on a schedule of its own (PROP_ADVERT_INTERVAL, PROP_BEACON_INTERVAL, PROP_STARTUP_BEACON). Requires CAP_DEV_IDENTITY, since what an advertisement carries is the device identity.

ALERT

CAP_ALERT — the device has some means of making itself physically conspicuous on demand (PROP_ALERT). It says nothing about which means, so a host must not assume audibility.

BATTERY

CAP_BATTERY

BLE

CAP_BLE — the device has a Bluetooth transport whose reachability it can turn on and off (PROP_BLE_ENABLED, PROP_BLE_LINK). It says nothing about the stack underneath, and in particular does not promise that clearing PROP_BLE_ENABLED powers a radio down.

CMD_MULTI

CAP_CMD_MULTI — the device accepts CMD_PROP_MULTI_GET and CMD_PROP_MULTI_SET and answers them with CMD_PROP_ARE.

DEV_IDENTITY

CAP_DEV_IDENTITY

DEV_NAME

CAP_DEV_NAME

GNSS

CAP_GNSS — a GNSS receiver is fitted, so the positioning properties exist and the wall clock has a source that can set itself. Requires CAP_TIME.

HOST_AUTO_ACK

CAP_HOST_AUTO_ACK (requires CAP_HOST_KEYS and CAP_HOST_RX_QUEUE)

HOST_FILTER

CAP_HOST_FILTER

HOST_KEYS

CAP_HOST_KEYS (requires CAP_HOST_FILTER)

HOST_RX_QUEUE

CAP_HOST_RX_QUEUE (requires CAP_HOST_FILTER)

IDENT

CAP_IDENT — the device serves and configures its own advertised node identity (PROP_IDENT, PROP_IDENT_ROLE, PROP_IDENT_MOBILE). Requires CAP_DEV_IDENTITY.

ILLUMINANCE

CAP_ILLUMINANCE — an ambient light sensor is fitted, so PROP_ILLUMINANCE reads a measurement rather than nothing.

MAC_BACKHAUL

CAP_MAC_BACKHAUL — the device can carry the host on a point-to-point link to its own node (PROP_MAC_BACKHAUL). Requires CAP_REPEATER: without a repeater there is nothing on the far side of that link to carry the host’s traffic onward.

PHY_DUTY_LIMIT

CAP_PHY_DUTY_LIMIT

PHY_LORA

CAP_PHY_LORA

REBOOT

CAP_REBOOT — the device can restart its hardware on command (CMD_REBOOT). A device that cannot — one whose ULCP session is a process rather than a board — leaves this out and answers the command STATUS_UNIMPLEMENTED.

REPEATER

CAP_REPEATER — the device can act as an autonomous mesh repeater (PROP_MAC_REPEATER_ENABLED). Requires CAP_DEV_IDENTITY.

SAVE

CAP_SAVE

STATS

CAP_STATS — the device keeps traffic counters and will report them (PROP_STAT_*). The forwarding counters additionally require REPEATER: a session with no node of its own behind it never repeats anything, and reporting zero forwards would read as a repeater that has done nothing rather than as no repeater at all.

TIME

CAP_TIME — the device keeps a wall clock (PROP_TIME, PROP_TZ_OFFSET). It says nothing about where the time comes from or whether it survives a power cycle.

WRITABLE_RAW_STREAM

CAP_WRITABLE_RAW_STREAM
