This morning I rebuilt a custom Overo kernel with rfkill enabled,
because I need to switch WiFi and Bluetooth transmitters on and off from
After the Gumstix booted up, I tried this command to shut off WiFi:
echo 0 > /sys/devices/virtual/ieee80211/phy0/rfkill0/state
I had another laptop scanning wireless networks, and the Overo ad hoc
network remained visible. The network only disappeared when the Gumstix
was powered off. No computers were actually connected to the ad hoc
network during this test.
On the other hand, doing "ifup wlan0" results in error 132. When the
rfkill state is set back to 1, it becomes possible to "ifup wlan0" again.
Any ideas how to get rfkill to do its job?
Is rfkill even supposed to work on the Overo?
