Hello Dexter,
Good day. Thank you for your question.
The device will provide information such as GPS elements(longitude, latitude, altitude, satellite, speed, and angle) and timestamps which fall under the AVL data (in AVL Data Packet). So, for GPS Heading you will require the server-end to exhibit the changes in the coordinate that are received from the device, as the device (configurator) only shows the live data.
Please let me know if you have any questions.
Kind regards.
