Dear Forum,

I've found in datasheet that CYW20706 supports CTS wake up when talking about HCI UART

1. Low-power out-of-band BT_WAKE and HOST_WAKE signaling (datasheet section 1.1)

2. The CYW20706 UART can perform XON/XOFF flow control and includes hardware support for the Serial Line Input Protocol (SLIP).
It can also perform wake-on activity. For example, activity on the RX or CTS inputs can wake the chip from a sleep state
  (datasheet section 5.3)


Would you please tell how to implement the BT_WAKE or HOST_WAKE via UART?

Thanks!

Best Regards,

Tim Yu

There are dedicated pins to do BT_Wake (Pin F8) and BT_Host_Wake (F7) to realize these functions. For reasons that a pin can be multiplexed with other roles, make sure that they are explicitly selected for it in the applications.

Thanks a lot!

I checked the latest datasheet. The CTS wake up description has been removed.

Best Regards,

Tim
