undervoltage issue?
(01-27-2018, 03:05 AM)WiFi Disable Question: Wrote: Please see http://forum.freeplaytech.com/showthread...475&page=4

Thanks, with rfkill I can toggle WiFi and Bluetooth through RetroPie menu. Unfortunately, the WiFi module is still "active". Using "dtoverlay=pi3-disable-wifi" will disable the module itself, so software can't reactivate it. I can not prove it, but I suspect that the solution with "rfkill" still consumes power/performance. 

I would like to pick up a few ideas from the "rfkill" solution to implement another idea. I want to write scripts that will modify settings files:
  • disable-wifi.sh
  • disable-bt.sh
  • enable-wifi.sh
  • enable-bt.sh
These scripts are available through RetroPie menu and will modify 2 settings files:
  • /home/pi/wifi-settings.txt
  • /home/pi/bt-settings.txt
These settings files will just contain "dtoverlay=pi3-disable-wifi" or "dtoverlay=pi3-disable-bt" (if disabled, othwerwise they are blank).
Disadvantage: With this solution, the device must be restarted for the settings to take effect... It's OK for me...

My problem is:
I mount my boot partition readonly to avoid SD corruption. So I can't modify my /boot/config.txt directly. My idea is to "include/load" my 2 custom settings files through config.txt, so I have to modify my config.txt only once (make boot partition writeable -> modify config.txt -> make boot partition readonly again). 
I don't know how to include/load my custom settings files through config.txt!?  Huh

I've described my issue here, too:
