A client that specifically needs one of the two - for example the Ranging Service, which distinguishes notification and indication transports - has no way to request it. Add bt_gatt_client_register_notify_with_ccc() which takes the desired CCC value (0x0001 for notifications, 0x0002 for indications) and writes it verbatim. register_notify() gains a ccc_value argument and rejects a value the characteristic does not support. The existing entry point keeps its behaviour by passing 0, which restores the property-based selection.

Some services need the indication transport for a given characteristic regardless: the Ranging Service must indicate Ranging Data Ready and Ranging Data Overwritten even when the client subscribed to both transports (RAS 3.4.2, 3.5.2). Add gatt_db_attribute_indicate() alongside gatt_db_attribute_notify() and let the callback query which of the two it was invoked from through gatt_db_attribute_indicate_only(). Both entry points share a helper, so the CCC lookup stays in one place, and neither gatt_db_notify_t nor the existing gatt_db_attribute_notify() callers change. gatt-database honors the request by skipping the notification branch and sending an indication instead, provided the client enabled indications.

The On-demand Ranging Data, RAS Control Point, Ranging Data Ready and Ranging Data Overwritten characteristics are delivered as notifications or indications according to how the client configured their CCCDs. Ready and Overwritten gain a CCC write callback so their subscribed transport is tracked, and a Ranging Counter each so a read returns the value last notified. When a client enables both transports (0x0003) the spec does not pick the same one everywhere, so the two rules are kept in separate helpers: Ranging Data Ready and Ranging Data Overwritten are indicated per RAS 3.4.2 and 3.5.2, while On-demand and Real-time Ranging Data are notified per RAS 3.2.2 and 3.2.3.1. The RAS Control Point is indicate-only. Ranging data is segmented across ATT PDUs, and it was queued a whole transfer at a time. Notifications land on the att write queue, which pick_next_send_op() drains ahead of the request queue and with no flow control of its own, so doing that starves incoming ATT operations until the last segment has been written: a Control Point write arriving mid-transfer is only answered once the transfer ends. Send one segment at a time instead. Indications go out with bt_att_send() and the next segment is queued from the confirmation callback; notifications have no confirmation to gate on, so the next one is queued from a short timeout. Either way a single segment is outstanding, so an Abort Operation stops the transfer rather than letting a queued one drain out. The notification delay cannot be zero: a zero timeout yields the event loop without waiting, so a Control Point write is only seen once it has already arrived, and a short transfer can finish before an Abort crosses the air interface. Against RAS/SR/SPE/BI-05-C, which writes an invalid Abort Operation mid-transfer, 0 ms fails and 5 ms passes, so use that.

Abort clears the sending state and removes the pending segment timer. Since the transfer keeps at most one segment outstanding, dropping that timer stops the transfer instead of letting a queued backlog drain out. The Control Point busy check lets Abort through while every other Op Code is answered with Server Busy, so an abort is accepted mid-transfer. On the requester side, an Abort is written when a Get_Ranging_Data request times out and the peer advertises Abort support, so the responder does not keep sending data for a request the requester gave up on. The unit test Features value changes to 0x05 accordingly.

The watchdog the requester arms while waiting for a Control Point response covered the first of those, but ran for 10 seconds, so it would abort well after the specified deadline. Arm it for 5 seconds instead. The per-segment deadline is handled separately by ras_cp_arm_segment_timeout(), which uses RAS_SEGMENT_TIMEOUT.

Completed ranging-data segments are queued in a per-connection FIFO and delivered on the Real-time Ranging Data characteristic, honoring the transport selected by the client's CCCD: notifications are paced with a fixed inter-segment interval, while indications are driven by ATT confirmations so the next segment is only sent once the previous one is acknowledged. The pending real-time segment queue is cleared when a new CS procedure starts, so stale segments from an aborted or superseded procedure are never delivered to the peer.

Setting a mode first unsubscribes whatever is currently subscribed, so the modes do not stack, and fails when the RAS Features read has not completed or the peer does not advertise the mode being asked for. The requested transport applies to the RAS Control Point, Ranging Data Ready and Ranging Data Overwritten characteristics. On-demand Ranging Data itself stays on notifications whatever is asked for: it carries the segmented transfer, and gating each segment on a confirmation would slow a large one down for no benefit on the receiving side. On-demand mode also reads Ranging Data Ready once subscribed, to pick up a counter published before the subscription existed. Real-time reception is guarded by the deadlines RAP 4.4.1.1 sets for the Requester: the CCCD is disabled again if no first segment arrives within 5 seconds, or if more than 1 second passes between continuation segments, so a peer that stops sending does not leave the subscription open.

Every case is listed on its own row rather than collapsed into a range, so the file states which cases were actually run. RAS/SR/SPE/BI-02-C is listed as not applicable: RAS.TS Table 5.1 selects it only when Abort Operation is unsupported (NOT RAS 3/4), and the IUT supports it, so RAS/SR/RCP/BV-03-C and RAS/SR/SPE/BI-05-C cover that path instead. ras-pts.rst also records which transport the server must pick when a client enables both notifications and indications, since the rule differs per characteristic and each variant has its own case.
