These ideas have been taken from the patches I found in [1]. The last patch, ?Bluetooth: Remove outgoing MTU check? should be considered with care, since there probably are better approaches to solve this (WIP). > > The BlueZ userspace patches add some necessary infrastructure to support such use-cases. > > The PulseAudio patches provide some changes to be able to test the rest of the code. The first three patches have been reused from a previously submitted patch series, and only the last two patches are relevant for this purpose. They provide some simple workarounds and should not be considered a proper solution. > > As I said, the easiest may to test these patches is by using two Bluetooth headsets.
