FX Firmware Release Notes

Overview

This page is the public release history of the BATCAM FX firmware. It lists the new features and changes in each version, newest first, and covers releases after v1.0.2. The latest release covered by this document is v1.0.4 (2025.11.25).

Depending on the release, an SbRIO firmware update may be included in addition to the main firmware version (v1.0.x). Both versions can be checked with the device information API.

Checking the Installed Version

You can check the firmware version installed on the device with the REST API GET /setting/status (device information) endpoint. It requires HTTP Basic authentication and returns the hardware information and firmware version of the BATCAM FX. Check the version and update whenever new firmware is available.

    "sbrio_version": "1.0.14",
    "firmware_version": "v0.0.1"
  }
}

The firmware_version field in the response corresponds to the versions in these release notes, and sbrio_version shows the SbRIO firmware version included in each release. For the detailed specification, see the FX API Playground.
