The BLE.Config gives `ValueError: unknown config param` with pairing parameters

bug

When running the example 'ble_bonding_peripheral.py' on the PICO-W the BLE.config method (line 70) gives ValueError: unknown config param. This error is repeated for all the pairing parameters. Given that it occurs at the low level, the aioble library gives the same result when calling the pairing methods.

Reproduce: Run the ble_bonding_peripheral.py example on the PICO-W (all I have).

This builds on #6651 . Changes to that PR are:

rebase on latest master (to get new CI to run)
fix build on esp32
minor updates to docs
fix bug in example with i += 1
added basic multitests for pairing and for pairing+bonding

Assessment

S Sonnet · medium

PR #6662 implements pairing/bonding support for BLE.config() — precisely the functionality that issue #13599 reports as missing. The PR adds pairing config params to extmod/modbluetooth.c and includes NimBLE support in extmod/nimble/modbluetooth_nimble.c (the stack used by PICO-W/RP2), and it creates ble_bonding_peripheral.py — the exact example the user is running. The ValueError: unknown config param is the direct symptom of pairing parameters not being registered in BLE.config(), which is what this PR adds. The user is on v1.22.1; if PR #6662 was merged before that release, the bug may indicate an incomplete RP2-specific implementation in the NimBLE backend. Confidence is medium because it cannot be confirmed from this data alone whether the PR was fully merged and whether NimBLE coverage was complete at the time of the affected release.

Suggested action

Check whether PR #6662 was merged and when. If merged before v1.22.1, the issue may reflect an incomplete NimBLE/RP2 implementation within that PR — investigate `extmod/nimble/modbluetooth_nimble.c` for missing config param handlers and file a targeted bug or follow-up PR. If #6662 was not yet merged at the time of v1.22.1, close issue #13599 as a duplicate resolved by the eventual merge of #6662.
