Thanks for the idea. I tried the following: sudo -i rtcwake -m mem -u -t $(date +%s -d "2 minutes"); ifconfig wlan0 down; ifconfig wlan0 up
The device went to sleep, woke, but did not re-establish effective wifi. As usual, the blue led was on, but the BeagleBone-A6XX Access Point was not visible. I had to use a shutdown -h now to restore the AP. Any further suggestions? Thanks for your time.
