This might be a little bit of a lengthy problem, so I’d appreciate any and all help. Simply put, I’m installing a number of Raspberry Shakes in the ground as a part of some graduate research. We’re hooking them up to a battery and using one of the GPS antennas sold by RS to provide the NTP. The plan is to leave the ethernet cable plugged in on one end to the RS and visit periodically to download data onto the laptop via the ethernet cable. I’ve run into some baffling technical problems that I just can’t seem to figure out. Simply put, the Shake doesn’t seem to be able to be powered off and then turned on again while using the GPS for an NTP without ceasing to use it and defaulting to a different time. And now additionally, I cannot even access the web front end of the Shake when it is set up normally on my home network. (Additional details follow)
I’ve been plugging my Shakes into my local home router (the university one doesn’t really work for this) to get them set-up with the wireless antenna, powering them down and then powering them up back again unattached to the router. I then will plug my laptop in via the ethernet cable and check to make sure it’s synched to UTC. This generally works fine, but lately when I power the RS back on, usually hours or a day later to install them, the Shake has lost its NTP and has defaulted back to the time that I turned it off. I’ve used Putty to check and I can still see that it can see the GPS plugged in, but its not using it for its NTP. I’ve made sure never to turn the Shake back on without the GPS antenna attached and always in places where it can actually pick up the satellite signal, but no dice. Sometimes it powers on with the NTP and sometimes not, apparently at random.
The secondary problem that has developed as I’ve tried to solve the first problem is that now even when I try to plug the Shake my home router to set up the GPS again and communicate with it, I can’t even pull up the web front end on any device or browser, despite the fact that it has worked previously. So I’ve essentially gone from being unable to keep the RS from using the GPS NTP to being unable to even safely shut it down. I ended up unplugging the Shake from the router and plugging the ethernet cable into my laptop to shut it down safely. I’ve made no recent changes to how my home network, so I’m kind of at a loss as to why this would suddenly stop working.
When I shut it down this time, I did download log files in case those would be potentially helpful in figuring out why I can’t use another device on my home network to access the web front-end. Any ideas would be appreciated, we have bought several Raspberry Shakes at this point, because they were inexpensive and easy to set up, but this issue has essentially brought me to a standstill. I’m happy to provide any additional details or try any suggestions!
