Number of simultaneous LD2410C devices on ESP32

Hi,

I am building my automations now based on presence detection with LD2410C devices.

I used an ESP32 like a Bluetooth proxy, but I was only able to connect 3 devices and they got randomly disconnected.

So I now use the built in BT chipset in my mini pc where my HA is installed as a docker.

My built in BT again only detects 3 LD2410C simultaneously and the ESP is not detecting any additional one. I read that there is a limit of 3 connections per BT receiver. But I don’t now how to move from 3 to 6 devices considering the built in receiver + ESP, and also how to grow further than that in the future.

I have looked for a guide on how to force BT device connections or how to create a farm of ESP32 as BT proxies, but no luck.

Can any of you give me clarity on limitations of my implementations and how to move forward to build a +10 LD2410 installation?

Thanks
