For those who are using the laptop with Intel BT module 8087:0029:

The firmware in the current 20.04 is: md5sum
8cadd1fa93ab9790f61165f384466b0d  ibt-20-1-3.sfi

The firmware in the current 20.10 is: md5sum
a2ebb8594804b5230a406b536804988c  ibt-20-1-3.sfi

The hsp/hfp could work in the 20.10 but couldn't work in the current
20.04 due to the firmware difference.

There are 3 new commits applied to 20.10 firmware:
