5.1 Setup and Configuration

AP ELP mode requires modifying the wl18xx-conf ini file AP ELP attributes. Currently the only supported attribute is:

wl18xx.ap_sleep.idle_duty_cycle: Duty Cycle (0-99%) for awake portion of the AP when in idle mode. Default is 0x00 meaning AP is always awake.

The following AP ELP attributes are currently not supported:

wl18xx.ap_sleep.connected_duty_cycle: Duty Cycle (0-99%) for awake portion of the AP when there are connected stations. Default is 0x00 meaning AP is always awake. wl18xx.ap_sleep.max_stations_thresh: Maximum stations that are allowed to be connected to AP before disabling the feature (255: no limit). Default is 0x04. wl18xx.ap_sleep.idle_conn_thresh: Timeout for enabling the AP Sleep after traffic stops. Units are 0.1 seconds. Default is 0x08.

It can be done by changing the values in the default.conf file and create the bin file from scratch:

$ cd /usr/sbin/wlconf
$ vi default.conf

Set the wl18xx.ap_sleep attributes to the appropriate value, exit and save.

$ rm wlconf-18xx-conf.bin
$ ./wlconf –D  (a new wlconf-18xx-conf.bin will be created)
$ cp wlconf-18xx-conf.bin <conf-bin> (Where <conf-bin> is usually /lib/firmware/ti-connectivity/wl18xx-conf.bin)
Alternately, it can be done by editing the existing bin file by:

$ cd /lib/firmware/ti-connectivity
$ ./wlconf -i wl18xx_conf_bin -o wl18xx_conf_bin --set wl18xx.ap_sleep.idle_duty_cycle=0x14

This will set the AP to sleep 20% of the time when in idle mode.
