c# - c#, Bluetooth get all in range paired undiscoverable devices

Question

I have been quite a while on this problem. I was unable to detect undiscoverable devices in range. Yes, it is a safety precaution to make device undiscoverable, yet if device were paired wouldn't it be fair to allow detecting it while in range?

BluetoothClient client = new BluetoothClient();
BluetoothDeviceInfo[] devices = client.DiscoverDevices();

This is the code which does not provide needed functionality. I came across this link. It states that it is possible to get devices in range which you have MAC address of (which I would have).

1. Is it possible inside 32Feet.net library to discover an undiscoverable bluetooth devices and how?
2. To check if device I know MAC address of would be in range even in hidden mode and how?
3. To get undiscoverable paired devices in range and how?

P.S. I am so desperate that even malware like solutions would be welcome.

Answer 1

阅读主题让我意识到这只能通过定制的蓝牙模块（涉及硬件制作）来完成。

1. 不，不可能在 32Feet.net 库中发现蓝牙设备。
2. MAC 地址仅对定制的蓝牙模块有帮助，而对于常规硬件，这是不可能的。
3. 这也是不可能的。

总而言之，在没有必要知识的情况下制作自定义蓝牙模块将花费太多时间和精力来完成这项任务，而且不值得。
