| File | Purpose | Download |

os4_receiver_v23.boot_app0.bin |

Maintenance and bug-fix release on top of v22's receiver-side configuration query/set protocol. No wire-protocol changes from v22 — the v22→v23 jump is fully drop-in.
- Already in the field? — OTA flashing (only needs
os4_receiver_v23.bin). - On the bench? — Flashing a receiver.
| Dongle FW | Compatible? | Notes |
|---|---|---|
| v16+ | Yes | Recommended pair. |
| v10–v15 | Partially | OTA works (since rx v15 / dg v10), but rxcfg returns no RECEIVER_CONFIG_RESPONSE; the host falls back to defaults. |
| ≤ v9 | No | Dongle won't drive the OTA hot-path; updates must be wired. |
