Explanation
Arrr, the changes meet both active coding objectives. For [
#1194],ble_sm_ltk_req_rxnow finds the connection while holding the host lock, unlocks, and returnsBLE_HS_ENOENTwhen the connection is gone. This prevents the invalid-connection NULL dereference. For [#1190], the Mbed TLS 4.x path inble_sm_alg.cuses PSA crypto headers and no longer includesmbedtls/cipher.h; the legacy path keeps the legacy headers. No issue-specific automated test requirement is stated.

Explanation
Arrr, the pull request includes changes not connected to [
#1194] or [#1190]. Examples include RSSI and PHY controller changes, Bluetooth 6.2 and 6.3 constants, ATT response behavior changes, deprecated GATT API removal, RAM store removal, NVS namespace changes, and broad controller and host behavior changes. The current PR description states only fixes for the two linked issues. These changes expand the scope beyond those objectives.Resolution
Remove the unrelated NimBLE core update changes, or link active coding requirements that justify each additional change. Keep the connection lookup fix and the Mbed TLS 4.x compatibility fix with their supporting code and tests.

Review comments at @src/nimble/nimble/controller/src/ble_ll_adv.c:
- Line 1167: Declare phy_mode whenever BLE_LL_PHY is enabled, independently of
BLE_LL_CFG_FEAT_LL_EXT_ADV, so the legacy-only PHY configuration can compile;
keep any extended-advertising-specific logic separately guarded.
Review comments at @src/nimble/nimble/controller/src/ble_ll_sched.c:
- Around line 532-534: Update the CSS first-event scheduling calculation around
css->period_anchor_ticks to convert BLE_LL_CONN_INIT_MIN_WIN_OFFSET from slots
to timer ticks with ble_ll_tmr_u2t before adding it to earliest_start, and
reduce the first-event max_delay by the same offset so scheduling delay cannot
exceed the connection interval.
Review comments at @src/nimble/nimble/host/src/ble_att_svr.c:
- Around line 1758-1759: Update the MTU check in the response-building path
around OS_MBUF_PKTLEN(txom) so it verifies that both bytes of tuple_len fit
before appending the length field. If they do not fit, stop before adding the
tuple to keep the response truncated at the tuple boundary.
Review comments at @src/nimble/nimble/host/src/ble_gattc.c:
- Around line 3372-3375: Update the failed `os_mbuf_pullup` branch to set an
allocation error and exit through cleanup that does not inspect `*om`; ensure
execution cannot reach the later `OS_MBUF_PKTLEN(*om)` check after `*om` becomes
NULL.
- Line 3402: Update the multiple-handle read response parsing around
proc->read_mult to accept an available final value truncated at the MTU
boundary, even when not all requested values are completed; continue rejecting
incomplete length fields and invalid surplus data detected via
OS_MBUF_PKTLEN(*om).
Review comments at @src/nimble/nimble/host/src/ble_hs_stop.c:
- Line 72: Keep the host in STOPPING throughout ble_hs_stop_done cleanup:
publish OFF only after controller reset and GAP state cleanup finish, while
releasing the host lock as needed so ble_gap_reset_state can acquire it. Ensure
ble_hs_start cannot proceed during that cleanup.
Review comments at @src/nimble/nimble/host/src/ble_sm_alg.c:
- Around line 707-719: Update the declaration of g_trng and the trng/trng.h
include so they are available whenever BLE_SM_SC and TRNG are enabled, including
BLE_CRYPTO_STACK_MBEDTLS builds; remove the backend-specific guard that
currently excludes them.
Review comments at @src/nimble/nimble/host/src/ble_sm.c:
- Line 1399: Replace ble_hs_conn_find_assert() with the non-asserting
ble_hs_conn_find() lookup in the LTK request path, so the existing null check
can return BLE_HS_ENOENT when the connection has already been removed.
Review comments at @src/nimble/nimble/host/store/config/src/ble_store_nvs.c:
- Line 45: Restore configurable bond-namespace selection in the NVS store
instead of always using the fixed `NIMBLE_NVS_NAMESPACE` value. Reinstate the
`set_nimble_nvs_namespace()` implementation declared in `nimconfig.h` and ensure
bond storage uses the selected namespace while retaining `nimble_bond` as the
default.
Review comments at @src/nimble/README.md:
- Line 33: Add descriptive alt text to both workflow badge images in the README,
identifying the build_cc_target and build_all_apps workflow statuses so
screen-reader users can distinguish them.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Arr, the uECC ble_sm_alg_gen_dhkey path returns 1 when it succeeds. This breaks every TinyCrypt Secure Connections pairing.
Line 840 assigns the result of uECC_shared_secret to err. TinyCrypt returns TC_CRYPTO_SUCCESS (1) on success. On the success path, err stays 1 and falls through to done:. Line 852 then returns err, so the caller gets 1. In ble_sm_sc.c (lines 631-638), any nonzero rc sets BLE_SM_ERR_DHKEY. Because of this, every TinyCrypt build fails the DH-key step, for example nRF5x targets without Mbed TLS. Before this refactor, the success path returned 0. Ye need to reset err after a successful exchange.
🐛 Proposed fix
err = uECC_shared_secret(pk, priv, dh, &curve_secp256r1);
if (err == TC_CRYPTO_FAIL) {
err = BLE_HS_EUNKNOWN;
goto done;
}
+ err = 0;
