GPS devices are connecting and disconnecting continually
Why is this in the server forum? Seems like a device issue to me.
Hi Ankit
I am also facing same issue from last 2-3 days in many Concox V5 devices. Is your issue resolved? Device connect to the server and then disconnect after some time and does not send my position data. In few cases, device sends all stored positions after few hours at once.
no my issue not solved yet even today i have cloned run on the vps without any modification but still facing same issues all devices are getting connected and disconnected and showing

if some one know the solution on this or any setting in the gps please let me know

you mean to say this is the device related issue? not from the server side?
