IRK in galaxy watch issue

Hello,
I dont know if this is a issue or maybe my particular problem.
I obtain the IRK of my 2 samsung watches (one watch5 and watch ultra).
I add it to the ble private devices, and perfect works.

But i see a strange scenario.
In both watches I have the home assistant app installed.
If I disable thee BLE transmitter in the watches (in the home assistant companion app), then the bermuda IRK stop working and detect away.
If I enable the BLE transmitter in the watches (in the home assistant companion app), then the bermuda start detecting by the irk devices.

I dont understand.
my intention is stop using the ble ibeacon transmission by the home assistant companion app, because the use of battery is very agresive.
But i dont understand why is stop working the irk detection when i disable de ibeacon :-(
