ESP32s Bluetooth Proxy not working (?)

ESPHome

I just re-flashed one of my esp32 and now seeing this in the logs:

[09:23:08][I][esp32_ble_client:064]: [0] [30:24:C4:00:03:11] 0x00 Attempting BLE connection

[09:23:08][W][esp32_ble_client:131]: [0] [] Connection failed, status=133

I assume this is an issue?

Is it “active: true” needed or advisable for xiaomi thermo/hygrometers only? I have currently disabled, but it still works… well, fine…

Esp-idf does a bit more logging. Some gatt errors are expected, and It’s only an issue if something is actually going wrong

I don’t think those devices need active scans

Same problem- Flashed with esphome bluetooth proxy. Was able to add it to HA, but it doesn’t pick up any of my bluetooth devices. Tried deleting the device (as my Pi bluetooth was able to initially add the device) but the esp32 still will not recognize it.

Got the same issue, it cannot detect 2 Inkbird TH2 thermometers for some odd reason.

I am seeing similar things:

And that is it, it does not find my Xiaomi Mi Temperature and Humidity Monitor 2 running this firmware: GitHub - atc1441/ATC_MiThermometer: Custom firmware for the Xiaomi Thermometer LYWSD03MMC and Telink Flasher via USB to Serial converter

These sensors works just fine with the same ESP32 module and Tasmota, but I would like play a bit with ESP home.
