Not working with Bluetooth Proxies (ESP32 based)

[bcutter]

While I was lucky to initialy set up this integration without any issues (#2 (comment)), I discovered by manually reloading the integration that:

• it will find the toothbrush just fine if it is pretty close to the Home Assistant server - a Raspberry Pi 4 which uses native Bluetooth
• it will NEVER EVER find the toothbrush if next to a Bluetooth Proxy (ESP powered, https://esphome.github.io/bluetooth-proxies/) - at the same time it can be discovered using the "LightBlue" app on an iPhone also next to the BT Proxy ESP

So where's the issue? Is it the BT proxy or this Sonicare BLE integration?

I bet this is one of the reasons for the most open "Can't connect to XYZ" issues in this integration, so really worth looking into this @GrumpyMeow! We should probably start asking for the specific bluetooth environment people use. I already found few users stating they are also using Bluetooth Proxy (e. g. here: #2 (comment)).

Thanks for sharing this. As stated, I can see the advertising messages of the Toothbrush in the BT Proxy Log, so I think it might be an issue of how the Sonicare integration reads/interprets these advertisement messages OR is the raspi BT passing BT messages differently than the ESP32 based BT proxies?

That's exactly the question I hope bluetooth experts like @GrumpyMeow can verify.

By the way: by only activating my toothbrush next to the BT proxy I could not find any activity in the logs (ESPHome). If i trigger other bluetooth devices (like SwitchBot buttons) next to the BT proxy, I see quite some activity.

I think I played around with the advertising window / intervalls and could see the activity immediately when lifting the TB out of the glass...

So, I've teste getting quite close to the server (like 2m) and the toothbrush was finally discovered. 😃

Now I will vote to add support for Bluetooth proxy. 😉

Same problem. Bluetooth proxy via the M5 atom lite via ESP home. @GrumpyMeow
Hopefully you got time to check were this could go wrong.

My toothbrush does connect if i'm close to my HA instance, but not from a Bluetooth Proxy. So, it would be great if support for Bluetooth proxies can be added.

@GrumpyMeow are you reading/still maintaining this project?

Same issue here, am able to connect via HA intgrated bt, but no luck via an esp32 based proxy.
