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

[Neil k8it]

it happened again. I checked it about 16 hours of on time and all was well. now the status shows that the node is not online.
The beagle bone blue led is flashing but the URI light green  is solid on. I have no linux login when I try to connect using putty. so by my estimate it occurred in the last 3.5 hours. the on time should be about 19.5 hours if it was working. The node has no output right now.
I just rebooted the node about 2pm Eastern time and all is well and it is back online.
My daughter did tell me that the internet did get real slow for a few minutes when we where out.
Could this be the cause? and if so what can I do to tell the BBB to retry the internet connection until it reconnects, and why would this lock up the rf side of the simplex node? id;s for example should still work.

Neil,

There is nothing that should go to sleep on the BBB or RPi2 assuming you are using a wired connection. I do have some questions about what you mean by going to sleep.

Do you lose connection to the linux prompt or just the local connection via radio?

If you do have the linux prompt can you ping to somewhere and get a response?

ping ucsd.edu

I am not sure if you can answer this question but does the blinking green light on the USB FOB go solid or out when this happens?

If you go into the Asterisk client can you see the hungup line when you release the PTT of the radio you are talking to your node with?

Does the node ID or give any output when this "sleep" happens?

In the Asterisk client  you can key and unkey the radio manually to see if you have control. The command is -

susb key   
susb unkey

This should key the radio and turn on the red PTT LED. Make sure to unkey.

I have noted a "sleeping node" or node lockup issue after extended hours of no activity. 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%
Are there any thoughts or best practices to share?
