There again to discuss the problem of Bluetooth headset not working with Raspberry Pi 3.
I've done so many tries to make it working, but for the moment only A2DP is 100% OK.
For HSP/HFP, I can select the profile headset_head_unit but no sound is in or out.

Other people reported me that HSP works for them, but only by using USB-Bluetooth dongles.
So now I'm suspecting the combo chip Broadcom 43438, I think the problem comes from here.
My questions are:
- How can we get the firmware of this chip? Nothing found in Google.
- How can we check if its drivers and modules are enabled and working?
- How to see Bluetooth logs in Raspberry Pi?
