Hi all, Here's v10 of the patch, with some lints fixed. Also recapping the rationale, plus some additional information on testing so far. This is an implementation of the Android specification for streaming to hearing aids over Bluetooth LE, ASHA[1]. ASHA predates the LE audio specification, and has been supported in hearing aids for a while now, so I think this is worth supporting as these devices should continue to be in use for several years. I've reused the MediaEndpoint1 and MediaTransport1 interfaces at Luiz' suggestion. The flow is slightly different from A2DP and LE Audio in that there isn't really a negotiation step, so the endpoint and transport are both available on connection. Also included is a script to stream arbitrary audio to an ASHA device, which is handy for making sure that the implementation does work. I have tested this against an implementation on a reference board, and various folks in the community have also been kind enough to test the WIP patches on various devices, so tested devices include: * onsemi RSL10 board, reference implementation from the onsemi forums[2] * Signia Styletto AX * Oticon More * Starkey Arc AI 1200 The current implementation is written with a single device in mind. My plan is to take this to completion along with a PipeWire implementation to expose a single device for playback, and then do a second pass to support a pair of devices.
