Scan not returning devices - Pairing with Andriod devices shows Extended Inquiry Result on wireshark?

[hunt-build]

I have several devices I'm trying to pair with, using the ESP32 as a central device, connecting to various audio/HID devices and a weather meter.

Connecting to the weather meter works great.
Connecting to generic phone apps works great.

Trying to connect to some generic headphones, a media remote (next/previous/pause) does not work. I never see these devices in the 'Advertised Device Callback' method.

I was able to connect to these devices using an android device successfully, and grab the BT hci log from the tablet.

I have tried 3 different brands of headphones and 2 media buttons. Some claim to support 5.2. Same result. Never makes it through the stack to the advertised device callback. I've attached a screenshot of one such device.

I don't know if this is a limitation of the ESP32, a configuration error, or a user error (I'm sure bonding is a part of getting this to work but I don't even get that far).

Any ideas? My scans are returning 70-150 devices, but never my HID devices which seem to be using an extra communication mechanism wireshark calls "Extended Inquiry Result"

Thanks in advance!
