pine64-pinephone: error building pmos stable

Hello, I tried today to build the latest stable pmos for pine64-pinephone.
It fails with the following error:
ERROR: Could not find dependency 'firmware-rtl8723bt' in any aports folder or APKINDEX. See: <https://postmarketos.org/depends>

I enabled the nonfree firmware and selected phosh as UI.
My pmaports is at commit a07e2730 on branch v20.05

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
