Can't connect to phone

[UchihaYuki]

I use the exact same code on my esp32 and try to connect it from my smartphone (Xiaomi 12 Pro). Although it shows up under bluetooth devices, I can't connect to it.

Is there a way to see what happened?

PS:
There's an error in the code, this line

adv_data = bytearray('\x02\x01\x02') + bytearray((len(name) + 1, 0x09)) + name

should be turned into

adv_data = bytearray(b'\x02\x01\x02') + bytearray((len(name) + 1, 0x09)) + name

or you will get an error.
