Hi
Just a simple question.
Is it possible to hide bluetooth device name ?? Something similar than wifi AP hide setting.
I mean, once I have detected and configured on ESPHome and/or Home assistant, want to hide my bluetooth devices from mobile BTscan.
I do not want my neighbors to detect my devices.

To disable the display of the device in the system menu of Windows and other systems, you must disable the transmission of “AdFlags”.

Then the "Bluetooth" integration in Home Assistant will not work. The Bluetooth integration incorrectly interprets the absence of flags in the transmission. According to the BLE standard, if any data is not specified, then it should be taken by default as zero values. They refer to Bluez problems when working in passive mode:

"Passive BLE monitor" integration will work.

ESPHome with ESP32 only supports the BT4.2 standard, which is ten years out of date. Not recommended for use due to numerous missed receptions of BLE advertisements from sensors.
