Dear Friends,
I doing project for customer will realtime monitoring data using 4g module sim.
In the normal case(connection from flexy to sever is ok ) we use mqtt protocol to send data from flexy to sever (mqtt broker)
With lost connection case and reconnect we will send file in historical memory flexy via FTP protocol.
But the problem is when the lost connection is long > 8 hours . the file sent to FTP sever is heavy .How to break time to send may be 4 hours for 1 file ? we have capture start_time lost connect and end time_lost connect .Just use this to sent in the present case
Thanks for your help
