Software and updates | MediaKind Docs

Software management in the Fleets API is device-centric. You inspect the versions available to a device, then set fields on the device resource to choose what runs or preloads. The same surface produces support packages for diagnostics. For the product background, see Update device software.

List available software

Terminal window

curl -X GET "https://app.mk.io/api/v1/projects/<PROJECT_NAME>/fleet/devices/my-device/software" \
  -H "Authorization: Bearer <YOUR_TOKEN>"

Each entry reports its version and whether the device can move to it, through status.upgradeCompatible and status.downgradeCompatible. Check those before you target a version.

Choose how the update happens

Three device-spec fields control software, and the right one depends on whether you want to apply the change now or stage it for later.

To…	Set	Effect
Run a specific version now	`desiredSoftwareVersion`	The device switches to it. `softwareUpgradeState` moves `Switching` then `Idle`.
Stage a version without applying it	`preloadSoftwareVersion`	The device downloads it; watch `status.preloadedSoftware` for progress.
Always keep the newest staged	`autoPreloadLatestSoftware`	The device preloads the latest available version automatically.

Set the running version:

curl -X PATCH "https://app.mk.io/api/v1/projects/<PROJECT_NAME>/fleet/devices/my-device" \
  -H "Authorization: Bearer <YOUR_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{ "spec": { "desiredSoftwareVersion": "1.2.3.4" } }'

Preloading first, then setting the desired version once the download is complete, makes the actual switch fast and predictable.

Support packages

A support package is the main diagnostic bundle. List the packages held for a device (up to five, newest first), and trigger a new one:

curl -X GET "https://app.mk.io/api/v1/projects/<PROJECT_NAME>/fleet/devices/my-device/supportPackages" \
  -H "Authorization: Bearer <YOUR_TOKEN>"

curl -X POST "https://app.mk.io/api/v1/projects/<PROJECT_NAME>/fleet/devices/my-device/supportPackages" \
  -H "Authorization: Bearer <YOUR_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
    "metadata": { "displayName": "Audio sync issue" },
    "spec": {
      "description": "Investigating audio sync drift on the output stream",
      "name": "audio-sync-issue-20260415",
      "collectors": ["Logs", "Host"]
    }
  }'

Only description is required. Omit collectors to include all of them. The call returns 202 Accepted, and only one support-package operation can run on a device at a time.

Remove selected services

To remove services from a device, select them by tag. Take a backup first if you might need to restore the current configuration.

curl -X POST "https://app.mk.io/api/v1/projects/<PROJECT_NAME>/fleet/devices/my-device/removeServices" \
  -H "Authorization: Bearer <YOUR_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
    "metadata": { "displayName": "Remove audio services" },
    "spec": {
      "description": "Remove audio processing services",
      "selector": { "tags": { "include": ["audio"], "exclude": [] } }
    }
  }'

What goes wrong

An “upgrade” that becomes a rollback. Beam devices use a dual-bank mechanism. If the version you set matches the version already in the second bank, the device performs a rollback rather than a fresh upgrade. Confirm the target version is the one you intend.

A preloaded version that vanished. Software-bundle storage is limited, and the device deletes older bundles automatically to make room. Preload close to when you plan to apply.
A support package request rejected. Only one support-package operation runs per device at a time. Wait for the current one to finish.

What comes next

Backups and restores: create the rollback point before a software change.
Manage devices: return to the device resource and its site and network settings.
