}

A GATT characteristic operation / permission flag (BLE_GATT_CHR_F_*).

The operation flags become the property bits of the characteristic declaration (and gate what the ATT server lets a peer do); the *Enc / *Authen / *Author flags additionally demand a security level before the access is dispatched to the gatts_subscribe hook.

Variants

Broadcast

The value may be broadcast (sets the Broadcast property bit).

Read

The peer may read the value.

WriteNoRsp

The peer may write the value without a response (ATT Write Command). Independent of Write — a peer cannot use write-without-response unless this flag is set — but both kinds of write arrive as the same GattsEvent::Write, as NimBLE does not report which ATT opcode carried them.

Write

The peer may write the value with a response (ATT Write Request).

Notify

The value may be notified (unacknowledged). NimBLE adds the CCCD for you.

Indicate

The value may be indicated (acknowledged). NimBLE adds the CCCD for you.

AuthSignWrite

The peer may write the value with a signature (ATT Signed Write Command).

ReliableWrite

Sets the “Reliable Write” extended property (prepare/execute writes). The queued writes are coalesced by NimBLE and delivered as a single Write.

AuxWrite

Sets the “Writable Auxiliaries” extended property (the Characteristic User Description descriptor is writable).

ReadEnc

Reads require an encrypted link.

ReadAuthen

Reads require an encrypted link from an authenticated (MITM-protected) pairing.

ReadAuthor

Reads require authorization.

Not usable yet: NimBLE asks the application to authorize the access through the BLE_GAP_EVENT_AUTHORIZE GAP event, which this crate does not surface (it arrives as GapEvent::Other, whose response cannot be set), and NimBLE rejects an unanswered request — so setting this flag currently fails every read with “insufficient authorization”.

WriteEnc

Writes require an encrypted link.

WriteAuthen

Writes require an encrypted link from an authenticated (MITM-protected) pairing.

WriteAuthor

Writes require authorization. Carries the same caveat as ReadAuthor.

NotifyIndicateEnc

Subscribing (writing the CCCD) requires an encrypted link.

NotifyIndicateAuthen

Subscribing (writing the CCCD) requires an encrypted link from an authenticated (MITM-protected) pairing.

NotifyIndicateAuthor

Subscribing (writing the CCCD) requires authorization. Carries the same caveat as ReadAuthor.

Implementations

impl BleGattCharFlag

pub const fn repr(self) -> ble_gatt_chr_flags

The raw NimBLE flag bit (BLE_GATT_CHR_F_*). const, so it can be used to build a static service table (see the gatt_services! macro).
