This release adds signed OTA bundles and local, host-side IMU calibration.

OTA upgrade notes

Breaking API change: update_firmware() and ota-update accept signed OTA ZIPs only. Raw BIN input and the version, sha256, and expected_model overrides have been removed. The SDK reads version and compatibility fields from verified metadata.

  • Use inspect_firmware_bundle() or ota-inspect to verify signatures and display all metadata offline, including JSON output.
  • Supply an independently trusted PEM P-256 public key. The SDK checks signature, payload digest, size, encryption header, model, board and allowed starting versions before transmitting the inner OTA data.
  • Test-profile bundles require explicit opt-in. Reboot and full running-version verification are still required before an update succeeds.

openzilo ota-update firmware.ota.zip --public-key trusted-signing-public.pem

The existing firmware OTA wire protocol is unchanged. Device-side decryption-key matching and rollback enforcement remain device checks.

Local IMU calibration

  • Add six-face accelerometer calibration, stationary gyroscope bias fitting and independent validation.
  • Save validated profiles locally, bound to the device, exact firmware version, model and sensor ranges.
  • Add imu-calibrate accel, quick, full, show, and reset.
  • Add explicit calibrated streams in g and deg/s while preserving default raw streaming.
  • Calibration is computed and applied on the host; parameters are not written to the ring. Supported IMU contracts work without a new firmware image.

cryptography>=43 is now a required dependency.

Installation

uv add git+https://github.com/ziloai/OpenZilo.git --tag v0.6.2
uvx --from "git+https://github.com/ziloai/OpenZilo.git@v0.6.2" openzilo --version

Install the pcm extra when live PCM decoding is needed. Download assets include the Python wheel, source distribution and SHA-256 checksums.

Documentation and validation

  • English documentation
  • Changelog
  • Python 3.10-3.13 CI, 198 local tests, isolated wheel installation and offline OTA signature verification were checked.
  • Documentation links, anchors, language routing and publishing checks passed locally.

Device-specific OTA installation and calibration accuracy were not newly validated on hardware for this release. This SDK release contains no firmware images or production keys.
