[arm-allstar] how can i determine why a bbb node goes to sleep

[David McGough]

Neil,

The solid (or no) blue LED, rather than the typical heartbeat, indicates 
the BBB has crashed.  Enabling the watchdog should help the BBB to reboot 
after a crash/lockup.

Note that almost all crash scenarios I've ever encountered were due to
either a poor quality 5V power supply or due to ground potential bumps on
the USB interface, via the URI adapter. Assuming that the BBB power is
separate from the radio/repeater power, one test to try is power-cycling
the radio power while watching for any BBB issues--there should not be any
interaction. If there is interaction, you need to improve the ground
bonding and/or USB isolation.

This is one area where the RPi2's are far supperior to BBB's---the USB is
MUCH less sensitive to bumps/surges.

I try to key up the node when this occurs and get nothing. the status of the node shows connected and not keyed up. the timing of these sleeping periods seem random. some people have suggested starting a cron job to reboot on a regular schedule. rebooting the node does bring it back 100%
