I think you have unrealistic expectations. I don't think there is a
universal way to get all traffic (not just data frames) in unencrypted
form from one interface.
You'll get encrypted data on the air, but you'll still have some
information, such as the frame types and timings, which may be useful
There are command line tools for decryption, such as the openssl binary
that comes with OpenSSL. You should be able to decrypt the traffic.
Alternatively, you can dump the specific packets by changing the code of
hostapd or the kernel.
