Does the CYW5557x support 802.11mc?
802.11mc is a Wi-Fi protocol that enables devices to measure the distance to an access point via so called FTM (Fine Timing Measurement). FTMs allow devices to measure the distance with a high degree of accuracy by using Time of Flight (ToF) calculations. The CYW5557x does not support 802.11mc. For an overview of supported bands, interface security and more, see the Linux and Android Technical Brief.
