Certain Qualcomm controllers do not accept our settings for Host Buffer Size: < HCI Command: Host Buffer Size (0x03|0x0033) plen 7 zephyrproject-rtos#19 [hci0] 22.391048 ACL MTU: 27 ACL max packet: 6 SCO MTU: 0 SCO max packet: 0 > HCI Event: Command Complete (0x0e) plen 4 zephyrproject-rtos#20 [hci0] 22.391525 Host Buffer Size (0x03|0x0033) ncmd 1 Status: Invalid HCI Command Parameters (0x12) Likely due to the fact that we do not reserve space for any SCO packets in the Host. Other Controllers (Realtek) seem to not transmit any data at all in the Controller to Host direction if Controller to Host flow control is enabled. Document this fact in the User Guide so that users know what to do when this happens. Signed-off-by: Carles Cufi <carles.cufi@nordicsemi.no>
