traccar | Traccar GPS Tracking System | Map library

I need to check the compatibility of the GPS device communication protocol with the logging server. The application allows you to perform a test that compares the sent frame with the protocols it supports and checks whether it is possible to read this frame by already supported protocols. For this purpose, I wanted to use the shared test, but I get an error. https://github.com/traccar/traccar/blob/master/tools/test-integration.py

There are two files that are used so that traccar gps devices can be tracked publicly on an embed html page with an Open Layers map with traccar user token generated from the traccar server.

Now I see that Open Layers is using also Bing maps, so can I use Bing Maps as a default embedded map for the traccar instead of this default open layers map ?

Here is the original two files (one is the js file the second one is html file) for the traccar which is used to get embedded map on the html page:

This is my code:

I am creating a nodejs module which retrieve some data from a mysql database and insert into another mysql database after some data processing. My main requirement is to make the module alive 24 hours even there is no data in the first database.. it will just keep checking for any new data. But unfortunately the module just doing nothing after few minutes of running. My function is as follows:

I am attempting to write a GPS emulator with QT c++. It will be used to send data to Traccar tracking app. Traccar uses localhost port 5055 to receive packets and uses the data from the packets to plot a location. I have not been successful in getting traccar to read the packets. Traccar expects to see the packet in HTML format. I am not sure if my program is formatting the data correctly. All of the lines starting with //\ show what I have tried.

This is the part of the program that writes data to loalhost port 5055:
