-            The root cause of the malfunctioning GPS Tracker came from an error in referencing the wrong version of the ESP32 NodeMCU pin layout. Thus, leading to an incorrect pin configuration for the GPS Tracker. This mismatch between the expected and actual pin connections prevented the ESP32 NodeMCU from effectively establishing a connection and communicating with the GPS Tracker, rendering the entire system inoperable.

             After some alterations, the output initially showed "unknown" location but displayed the correct date. However, rerunning the code caused a glitch, and the date reverted to 2001. Suspecting that there might be a CMOS battery issue, i researched more about the GPS device. The online research revealed that the Neo-M6 GPS HAT with Antenna for Raspberry Pi lacks a CMOS battery for date maintenance. It relies on the Raspberry Pi's power supply, losing date and time information when the Raspberry Pi is turned off.

In this scenario, the ESP32 will be used to collect the GPS coordinates, which will then be transmitted to a MySQL database via an HTTP POST request to the PHP Webpage. PHP, a scripting language, will handle the server-side processing of receiving the data from the ESP32, and storing it in the MySQL database. Next, a python script with multiple libraries such as matplotlib and cartopy will be used to plot out the entire route and pathway of the security guard to visualise for areas of improvements.

+            For week 14, to enhance security and enable tracking of the assigned security guard, a bluetooth feature is implemented on the ESP32 Nodemcu. This feature requires the security guard to establish a bluetooth connection with the ESP32 Nodemcu using their mobile phone before the seer tracking device can begin its pathway tracking.
+            <br><br>
+            This bluetooth feature will capture the bluetooth mac address of the security guard's mobile phone. Since bluetooth mac addresses are unique, it allows the benefit to be used for the identification of the security guard. The captured bluetooth mac address will be stored in the database records along with the GPS coordinates and altitude data.

+            However, after integrating the bluetooth code into the main GPS Tracker, an error occurred due to the storage space being exceeded. This was caused by multiple libraries with initialised objects that consumed a significant amount of storage space. 
+            <br><br>
+            After some online research to find solutions for this issue, I came across some potential solutions that involves using older versions of the libraries to reduce storage space. However, implementing these older versions may result in the loss of some functionalities. As a result, I have decided to test and explore alternative solutions in the following weeks.
