Additional information

The device works fine (via LD2410 BLE) if the sensor is brought close to the RPI4. However, the sensor is not detected through the connected Bluetooth dongle (CSR8510 A10).

The built-in Bluetooth on RPi4 is disabled, and a CSR8510 A10 dongle is enabled (the Passive BLE monitor integration works perfectly).

I have esp32-bluetooth-proxy, having the same problem not showing the sensor. Can find it with the app, but not HASS.

Hello I have the same problem as you. I have a docker container of home assistant running on a server. I have a usb bluetooth dongle and the dongle works well with the passive BLE integration I use for temperature sensors. However, the LD2410 is not found as you. However, I can see the LD2410 BLE advertising packets through my mobile phone using the nrF connect app

[Judge-Tread]

Also having this issue. No autodetection, and inability so set up new device - I'm 3-4m away from the RP4 hosting HA, so Bluetooth connection should be fine

[tbrasser]

Seems these things need:

• to be very close to a bluetooth proxy
• a reload of the integration to be picked up

My system:

• HP T620, AMD GX-415GA 1.5 GHz Quad-core /AMD Radeon HD 8330E
• Internal Bluetooth
• Home Assistant OS
• LD2410B, powered with 5V

LD2410 is automatically detected in HA. I try to configure a box come up with the device name and MAC address. I click SUBMIT and it spins for randomly from 5 seconds to 30 seconds and then displays "Failed to connect". I can connect with the APP on my phone and it connects and stays connect, giving me the graphs and all.

Is there any configuration I can do from the APP that might fix this?

My thought is that the encryption failing several times causes the chip to reboot? Any thoughts?

I am having the same issue. Latest version of HA 2024.5.3. I am using Bluetooth proxy. Other Bluetooth devices connect fine. In fact, when adding the 2410 for the first time, it gets discovered. I was having an issue with one 2410 where it was unavailable, so I deleted it. Now it won’t get rediscovered. Same issue with two different 2410s.

[Orekaria]

I encountered the same issue on a Raspberry Pi 4.

Solution:

1. Navigate to the Bluetooth configuration: http://homeassistant.local:8123/config/integrations/integration/bluetooth
2. Disable Passive scanning

After doing this, the LD2410 was detected immediately.

Mine gets detected but fails to install with a USB Bluetooth dongle plugged in to my Home Assistant server. Using a Bluetooth proxy, it connects and works for a short period of time and then it disconnects.

I have the same problem with two LD2410Bs via Esp32 Bluteooth Proxies. Home Assistant Core 2024.8.0, ESPHome 2024.7.3. They aren't discovered reliably. On of them was discovered, but after i added it the connection was lost.
