Hi,
for obvious reasons we're trying to reduce the component count for one of our products and compensate as much as possible in software.
For this we would like to route HFP audio from SCO over HCI instead of the module's I2S interface. This technique works very well with certain TI modules but only because the modules send custom HCI packets to inform the host when to send the audio packets.
The only thing we could find out so far is that there are vendor specific HCI commands for the CYW43455 that do configure audio routing. What they are and whether they include configuration options for a solution as described above has been beyond our reach.
Does anyone have experience with this sort of setup or access to a proper command reference for custom HCI commands?
Thanks in advance!
Solved! Go to Solution.

Hello @FWilke
Not all the Vendor specific HCI commands are publicly available.
Can you please reach out through our local sales / FAE contact to create a case for this request ?
