The problem on C8 hub is not limited with old devices.
I have a ESP32-c6 Dev kit module which I am trying to build a new sensor with.
This is a very new device from Espressif
On C8 it was being stuck at "initializing" and I always thought that the Espressif's examples were not complete.
On C7 it pairs in about 10 seconds.
