Hi, everyone. I'm testing the power consumption of the WL1835MOD of BBBW. So I need to turn the WL1835MOD off and on to check the power consuming difference. I have tried several ways to turn it off but failed. The ways I tried:
1. ifconfig wlan0 down. No power consuming difference is observed. The WL led is still on after I tried the command. I guess the WiFi was not really off. 2. According to (http://processors.wiki.ti.com/index.php/WiLink8_WLAN_Demo:_Linux#Configuring_the_Target, "For low-power modes, the WL18xx chip can be held in a suspend/shutdown mode where it will draw minimal current in order to preserve battery life/minimize power draw. These commands can be run on any supported platform, including, but not limited to, the AM335x, AM437x, AM57x, and BeagleBone." After I followed the below instructions, almost every thing on the BBBW was turned off. But I only need the WL1835MOD to turn off. - mount -t debugfs debugfs /tmp/ - echo 1 > /tmp/pm_debug/enable_off_mode - mount -t debugfs debugfs /tmp/ 3. According to (http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays), I could disable WL1835MOD to boot by uncommenting #disable_uboot_overlay_wireless=1, but the wifi and bluetooth still boot up after I restarted the BBBW. Does anyone has any idea how to turn off the WL1835MOD?
