Hi Duy
Thanks for your response. What field exactly is relevant for this? Is there a
list of WBS-compatible Macs?
The main difference that I can see is that the newer one has the BCM20703A2
while the older has the BCM20702B0.
The other difference is that on the Air 2013, Bluetooth is connected via USB,
while in the MBP 2016 UART is used.
The PacketLogger shows the SCO packets just fine, so the Bluetooth server could
decode mSBC/WBS in both cases.
Thanks for more info!
Matthias
