bluetooth device conflict
I have hearing aids that have bluetooth that I use to accept and make calls on my iphone 11.
I also, sometimes, use my bluetooth speaker to listen to music, but I do not want to take calls on this device for a variety of reasons.
how do i change the settings so that my music and video audio goes through my speaker, but my calls (both send and receive) are managed though my hearing aids?
thank you
iPhone 11
