No-no, it's not about adapter powering off. I meant that (external) devices never disappear from the bluez device list during the discovery, even if the (external) devices are turned off (i.e. they should be purged by bluez). So: - bluez is central - bluez is discovering - peripheral appear for a moment, than disappear (i.e. peripheral would be turned off) - bluez would not remove device from the list (at least until discovery is stopped) Use case: - bluez is monitoring environment (discovering literally forever) - peripherals are brought in and out of bluez visibility range - bluez list of visible devices grows infinitely and causes problems (hundreds of devices) Thanks, Andrey
