RPA sails through the advertising tide,
Identity anchors now guide the ride.
Non-RPA strangers stay ashore,
Random flags hold fast once more.
Connections chart the proper course,
Yarrr, the list keeps its source.

- Line 569: Update the connection-target handling in ble_gap.c so that when it
substitutes rl_peer_rpa, it sets the target address type to BLE_ADDR_RANDOM
instead of copying rl_addr_type. Keep the scan report’s identity address type
unchanged.
Review comments at @src/nimble/nimble/host/src/ble_hs_resolv.c:
- Line 727: In the resolver path containing BLE_HS_DBG_ASSERT, acquire the host
lock before invoking the resolver and release it immediately after the resolver
returns, before delivering the scan callback. Ensure the resolver call is
protected even when invoked from ble_hs_hci_evt_le_adv_rpt without the lock
already held.

🟡 Minor · Arrr, clear rl_isrpa for a non-RPA identity report. · ble_hs_hci_evt.c:566

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winArrr, clear
rl_isrpafor a non-RPA identity report.A peer can first advertise an RPA and later advertise its identity address. The current report path sets
rl_isrpabut never clears it. A later legacyble_gap_connect()then replaces the identity address with the cached RPA andBLE_ADDR_RANDOM. The controller targets an address the peer is no longer advertising, so the connection can fail.Suggested fix

Review comments at @src/nimble/nimble/host/src/ble_hs_hci_evt.c:
- Around line 192-195: Update the address-resolution handling around
ble_hs_resolv_rpa_addr so identity-address reports also match their
resolving-list entry and clear rl_isrpa before delivery, while preserving the
existing RPA handling for BLE_ADDR_RANDOM.
- Around line 191-192: Update the address-resolution flow around
ble_hs_resolv_rpa_addr and only resolve or rewrite the reported address when
ble_host_rpa_enabled() is true; when runtime resolution is disabled, preserve
the advertised RPA so scan-then-connect targets it consistently.
