I've only just recently installed v1.5.2-RPi-Build1 on a Pi Model 3B+ and things were going reasonably smoothly. I was happily adding hosts and verifying that NEMS was able to detect if they were online, until I tried adding a host entry for my EtherRain devices - refer to http://www.quicksmart.com/qs_etherrain.html
NEMS kept reporting that the device was offline even though I could ping it from my windows 10 laptop. I tried manually pinging the device from the NEMS terminal and it failed as well.
I noticed that the windows ping was only 32bytes, but the default ping from the NEMS terminal was 64bytes. Just for giggles I found that if I manually set the packet size to be 32 bytes, it worked.
Code: Select all
ping 192.168.1.112 -> failed
ping -s 32 192.168.1.112 -> worked
ping -s 33 192.168.1.112 -> failed
