Hello All,
I am using Beaglebone black device for one of my meter reading IOT projects.
The following points are as per observation in the plant where project is implemented.
- The beaglebone black device reads Modbus data through RS-485 and sends it to remote cloud.
- The beaglebone uses wired ethernet (with static IP address) to connect with remote cloud.
- The issue i am facing is associated to internet connection:
a. after a certain point of time(mostly 1/2 minutes), the internet connection gets disconnected and if i run the following command
(/etc/init.d/networking restart), it starts working again for sometime and again i have to repeat the same procedure to
make it working.
b. for time being, i have applied a temporary fix with the help of crontab(restarting it after every two minutes),
but there are few services which needs continuous internet connection to work properly.
-
The IT team in the plant has specifically asked for configuring local and global nameserver in the resolv.conf file
-
The issue remains the same even if i configure either one of the nameservers in the resolv.conf file.
few observations:
-
the issue is tested with the help of ping command (ping to either the global namerserver or local nameserver fails ).
-
the issue is not observed in the laptop(tested using command prompt.)
-
The hardware(beaglebone black) works properly in other environments.
-
I have tried 2-3 hardwares(beaglebone black) in the same plant but the issue remains the same.
Can someone please help in highlighting what could be the reason behind this or any specific activity that i should follow to resolve this
thanks in advance.
