Description (partial)

After some 24-48+ hours, we can observe all APs admin-disabling their BLE radios without any manual config changes or loss of network connectivity. Issue does not seem specific to the USB module or embedded BLE Radio.
This causes CMX to fail location-tracking for all BLE Tags, as the APs no longer forward any data.
