[BUG] can connect to android, but not to (linux) pc

[prankousky]

Hi,

I was hoping to control my linux PC with this project. I flashed an ESP32, connected it to Home Assistant. I can find the device with two different android devices and connect to it. Some buttons will work, others won't. But connection and at least some buttons work.

But the device won't connect to my PC / my PC won't connect to it. It won't even discover it. It is discoverable, I made sure by testing if "start/stop advertising" works by pressing those buttons, then checking my android phones. When I do, the desired action will happen. So it should be discoverable when I click "start advertising".

However, it won't show. Since I know the MAC, I tried manually connecting and pairing it (via bluetoothctl and bluetuith), but am only getting "Device not available".

What can be done to fix this?

My entire configuration is attached below.

Please complete the following information:

• ESPHome version: 2024.3.1
• Component version: not sure how to find this; I included the lines below in my yaml, so I assume it is the most current, stable version..?
