Hello, Orange ,
On our part, there cannot be such a delay in receiving data from the device, if the device sends messages according to the protocol, we receive, process and display them in a matter of seconds without waiting for additional data from the device.
If you have any problem with the device, write to us at support@gps-trace.com and we will try to figure it out.
Based on the results of our conversation, in this forum on the topic, we will write a solution.
