Hi @zxzxwu
i don't know if this a propper place for asking question or not.

I have question with sco link.
i am testing HFP implementation and SCO Connection using Bumble.

my question is is the SCO Stream already implemented or not in bumble?

because when i try to register event scoLink.on('pdu') it is still not receiving any event.
how to receive or send audio data via the sco link?

@endrik-exe Not all controller support SCO over HCI. Unlike A2DP which is mandatorily required to be transmitted over ACL, SCO is quite customized. Many chip vendors integrate Bluetooth controller with their own audio DSP and disables the HCI path because it's quite complicated and in a bad performance usually. You may try with different SCO parameters to see if that work, but I guess no :/
