Hi,
I started my little project with an ESP32-CAM that connects to an Android app by bluetooth classic. It's working fine, can connect from any android phone, the board shows while scanning from any other platform (ios, macos, etc), etc, no issues at all.
Ran out of pins, so I'm trying now with an ESP32 WROOM (ESP32 DEV KIT V1?).
It's working fine on some phones, but on a specific phone (Samsung J3, which would be the one to use in the future) doesn;t show when scanning.
Trying with the most simple BT setup has the exact same results:
most Android devices can see the board, except the Samsung and an iphone.
BLE seems to work fine, but it would be too many changes and I'm also curious what could be the issue and to fix it.
What could be different from these two ESP32? How can I debug this? Any tips?
Thanks
