This is a semi proprietary Apple standard to send audio data over Bluetooth LE, but it is not something that we support unfortunately.

Most likely this standard will be replaced by LE Audio in the future, once LE Audio adoption is more common place.

Ok thanks.

I saw this which seems to suggest iOS supports LE hearing aids (this device might qualify as a hearing aid). Do you know what GATT service this is? Is this something we could use?

LE Audio is still a relatively new standard, and is not yet supported by any mobile platforms unfortunately. This includes the iPad, which will only work with legacy Bluetooth audio devices (which is not supported in any Nordic chipsets).

Also, we have only implemented LE Audio in the nRF5340 chipset. The reason for this is partly because of the relatively high CPU requirements of the audio codec, and in part that the nRF5340 has an improved clock system that is optimized for audio applications.
