Bluetooth proxy doesn't detect any device

Hello everyone, I configured an esp32 bt proxy, but it doesn’t detect any bt device.
I have 3 MiFlora (HHCCJCY01HHCC) and I tried with a new one just unpacked, the bt proxy seems to doesn’t detect anything.

ESP logs:

and that’s all…
I tried to disable my Xiaomi BLE + BLE passive monitor + Bluetooth integrations with a reboot, it’s the same behavior.

Anyone could help me figure this out please ?

Your scan only went for 22s.

No sorry I didn’t put much logs.
Here are logs for 20min (except api connection lines) :

Check via HA logging


I have the same issue. ESPHome Wroom 32, flashed with the BT Proxy, scanning witthout results. I’ve had no previous BT devices configured in HA. Any help?

Thank you!

Have you figured out the reason for that? I’m having the same issue on my end.

I was testing bt proxy with ATC Custom firmware (LYWSD03MMC), which seems to not be compatible.
Then I tried with MiFlora and it worked without changing yaml ESPHome config.

There is no real logging with bt proxy yet, so be sure to use a compatible bt device.
You can use this config template to make it working : bluetooth-proxies/esp32-generic.yaml at b75bed9b0d832b0c80d32870ba220a3298123484 · esphome/bluetooth-proxies · GitHub

Good luck

HI all…My BT Proxy first didnt find any devices…after a lot of rebooting and stuff i atleast got it to recognize a Switchtbot Curtain…

But it still wont connect… I get this (error) message:

[14:10:30][D][esp32_ble_tracker:327]: Starting scan…
[14:13:43][I][bluetooth_proxy:254]: [0] [EE:3B:05:F3:B3:FB] Connecting v3 without cache

[14:14:04][I][esp32_ble_client:078]: [0] [EE:3B:05:F3:B3:FB] Disconnecting.

Not sure what this means though. Can anybody tell me?

I know this is old but i am having the same problem with the same firmware. Do you know how to put the stock firmware back on?

If you just select BT Home (can’t remember the name of the setting) when flashing the Miflora, it will be discovered by HA via BT Proxy.
