[App_rpt-users] Repeater Stuck Locked open for 18 hrs

Wed Apr 25 23:31:53 UTC 2018

I remember his statement from long ago, and have been reminded of it many times over the past 5 years building and maintaining Allstarlink systems. My issues, and toughest to troubleshoot have all been USB centric... a hardware problem(sigh!) 

Thanks for the reminder. The quips and wit of “The Duuuude” are surely missed.

I’ve been looking for old GPIO threads from the past that addressed using scripts to control the interface for RPi shutdowns and PTT, but have not found them. Any suggestions?

Thanks,
Bob

In fact beside the fact that I receive an email from my asterisk system, I usely dont even know that my node was stuck or that a uri was not working properly. Am I lazy.. yup..

>>> I really dislike mechanical TOT. Why not use a small RPÏ that can monitor the 2 URI and use it to drive 2 or 3 relay? Those relay could, reset the MB, power off the radios, power off/on the router.

>>> A simple circuit that have a phototransistor that drive an input of the rpi would be easy to install, just use 2 small tube that cover  the geen  led to feed the phototransistor (maybe a simple straw would do!)  . pretty sur that just a npn phototransistor could be driven directly with just a small pull up resistor to make the sensing part of the circuit and the rest is just simple coding either in python or in C.  Could even had automation like ping fail that reset the router/wifi link. you could even monitor the ASL system for activity and compare the 'software state' to the hardware state.

>>> The way it stands at the moment I am not entirely sure… Here is what I found during reinstallation the Memory failed a self check that I ran while putting Windows on it to stress test the machine.. The hard drive doesn’t seem to want to take any data at this point.. But before attempting to format reinstall on this machine the system booted still.. My guess is some thing mechanical could have caused Asterisks to have failed at this point.. Honestly it seems to be a bit of a waste of my time to continue working on this machine when I have a second one exact specs sitting here ready to go.. We are doing the just in case TOT timer in the radios and this will affect autopatch users and anyone else that doesn’t let the system fully drop.. This is for my own re assurance that I have to the best of my ability solved the issue..

>>> Well technically it could have been controlled by the two meter repeater had the two meter repeater responded under normal circumstances.. What I am going to do for future repeater operations is to put TOT timers on the radio and I don’t care whether individuals on Autopatch that are calling Emergency services get disconnect etc because of radio tot.. No longer am I going to rely on asterisk to handle the TOT primarly.. Because of this experience.. We now know that we have fried some memory and possibly a motherboard but my testing at this point is stopping.. Moving forward with new gear..
