I have changed WiFiWmmPS=0 to WiFiWmmPS=1 at TI WLAN driver .ini file located at /system/etc/wifi/tiwlan.ini and did push using below command adb push tiwlan.ini /system/etc/wifi/tiwlan.ini ==> copied from my local to remote system directory After reboot, I have expected that handset MAC traces should WME/WMM QoS bits. Although my Access point is sending QoS Access Category as Voice. I am not seeing any power save bits for WMM/WME from my handset. Does TI WLAN driver supports WMM/WME power save for Wi-Fi? Are there any limitations or known issues? Any tips for debugging this issue are greatly appreciated.
