Error — old APK:

{
  "ok": false,
  "error": "U300 Relay endpoint /antennas/mask is not available. Update the U300 Relay APK to the latest build."
}

This 404 error means the relay APK predates antenna mask support. Update the APK.

Mask is applied to the relay immediately
If locationId is resolved and antennas.length > 0, the selection is saved to device_config as u300.antennas
On the next POST /ingest/start, the saved mask is reapplied before ingest begins
Sending an empty antennas: [] disables all persistence (relay default is used)
