    CYW20704: hci0 Connection timed out after toggling BT_RESET pin

    EdCh_3241771

      Hi,

      I would like to do a hard reset on CYW20704 based on the Bluez 5, after I toggled the BT_RESET ping to low/high, then the hci0 is no response.

      Is there anyway to recover the status? thanks.
