Hi, I have a device(ARM micro-controller) that send and transmit data each 100ms (maybe in sometimes it send and receive simultaneously but not always) with PC. After 4hours I lost my connection and I see this output:(Device IP:150 , PC IP:101)

I want to know why did I lost my connection? it is related to my PC or Device ? and How can fix this problem during the connection?

Thanks

Can you share a capture in a publicly accessible spot, e.g. CloudShark?

Thanks for your comment.The file size is approximately 96mb and unfortunately I don't know how can select some part of capture file.if there is no problem I can upload all file?

Cloudshark Preview imposes a 2MB max upload size limit, so a 96 MB is too big. Some possible options:

  • Sign up for Cloudshark for Business or Cloudshark Enterprise, which give you a 150 MB and 4 GB limit on capture files, respectively
  • Try to post it elsewhere, such as to dropbox, pastebin, etc.
  • Filter the data you have so it's smaller and "postable"
  • Take another capture with capture options set that cause a smaller capture file to be generated, such as by setting an appropriate value for the snaplen (maybe tcpdump's old default value of 96 bytes, for example), and/or applying a capture filter to only capture traffic of interest (e.g. tcp port 4050).
