I had an ESP32 doing ONLY BTProxy and it was working, then a couple of months ago I put an ESP32 in an IKEA Air Quality monitor so it could do double-duty, but the BTProxy doesn't appear to be working.

I just plugged my old BTProxy in and am trying it now.

real ember Feb 18, 2023, 7:45 PM

#

that's what i am using on mine

#

i had fast_connect on cuz i was using a hidden IoT SSID and it wouldnt connect without it but decided to unhide the ssid cuz with fast_connect it just chooses w/e the first AP it sees is instead of scanning for the closest/strongest

Just confirmed the old one is still working, so now I gotta figure out why the new one is not.

#

randomized keys?

#

or you accidentally leaking

cerulean widget Feb 18, 2023, 7:48 PM

#

The encryption key?

real ember Feb 18, 2023, 7:48 PM

#

password and keys there

cerulean widget Feb 18, 2023, 7:48 PM

#

No, I just dont' care if you see that, that key is literally so that one device can connect to HA

#

And the fallback hotspot? don't care about that either

#

i think we can just use what it's filling in with the url

cerulean widget Feb 18, 2023, 7:49 PM

#

There, fixed. I'm confident that was not a real security leak though

#

Now, to trouble shoot the combo device

real ember Feb 18, 2023, 7:50 PM

esp32_ble_tracker:
  scan_parameters:
    interval: 1100ms
    window: 1100ms
    active: true

bluetooth_proxy:
  active: true```

#

might just need that

cerulean widget Feb 18, 2023, 7:51 PM

#

The logs show:

[11:51:30][C][esp32_ble_tracker:584]:   Scan Duration: 300 s
[11:51:30][C][esp32_ble_tracker:585]:   Scan Interval: 1100.0 ms

oh, that's tracker stuff

hang on

That same file references itself(?) on line 28..

real ember Feb 18, 2023, 8:08 PM

#

Yea lol

#

Prob better if we just ask in the esphome discord

cerulean widget Feb 18, 2023, 8:08 PM

#

Exactly what I was thinking.

real ember Feb 18, 2023, 8:08 PM

#

I’m gonna nap you do it

Well, I did some mucking around, I removed the sensor information, compiled and installed it and BT Proxy was working.

Then I uncommented the sensor stuff, compiled and installed again, and now the sensor and the proxy work

You asked the wrong question in the esphome discord man

#

Seems our answer is all we need are the two lines Bluetooth proxy and active

#

I’m not even sure if we need the BLE tracker bit

cerulean widget Feb 19, 2023, 3:56 AM

#

The Bluetooth proxy depends on ESP32 Bluetooth Low Energy Tracker Hub so make sure to add that to your configuration.

#So we should update and change our
