 #GPRS/GSM Task - This task manages receiving and sending SMS messages. It sends a signal to the GPS task to obtain the current location, which is passed between the tasks using a queue. To communicate with GPRS module, UART 3 is used and its baud rate is set to 115200 bps. Then, the GPRS module is confirmed to be on by setting AT commands and getting a response. If GPRS module is not on, a reset signal and power signal are sent from SJSU One board.Then, SJSU One board turn off GPRS echo feature, and also setup the sending and receiving feature.

 == Testing & Technical Challenges ==
 === Android App ===
-In order to test this system. One student started to run the Android App from Campbell, CA and another student started to run the SJ One board from Sunnyvale. Clearly, the distance between the two student is more than 200 yards. Therefore, the Android will draw the Driving fastest route. When the user presses the “update” button, he/she will receive sms with the current latitude and longitude of the target. These message will never stop unless the user presses the “stop” button.  Figure 3  shows the screenshot of the app after pressing the update button; note that the app shows a path using freeway to the destination, and it prints its Latitude and Longitude. To protect the home location of our student, we “blind” the location of the destination. Figure 9 shows the screenshot of the app after pressing the stop button. This test shows that the android app is communicating with the SJ One Board using the GSM network and the SIM900 module. In addition, this test shows that the SJ One Board is communicating with the GPS module by requesting coordinate data.

 ==== Fastest Walking/Driving Path ====
-One of the technical challenge in this project was to find the fastest driving in the android app. Google Maps Android API v2 does not provide any API to draw a path between the source and destination; as a result, the gdaplibrary library was used. This library is not included in the Android source code, so the documentation is vague.

 == Conclusion ==
-Conclude your project here.  You can recap your testing and problems.  You should address the "so what" part here to indicate what you ultimately learnt from this project.  How has this project increased your knowledge?
+The Location Tracker is designed to keep track of where someone or something is. It brings together a microcontroller, GPS module, GPRS/GSM module, and Android phone to create a system capable of helping locate an object. The main objective of this project was to allow an Android phone to receive GPS coordinates of the object being tracked. This was accomplished by using a microcontroller to read GPS coordinates and sending the coordinates to the phone through SMS messages. The main challenge of the project was in the SMS handling at the microcontroller. SMS messages were sent and received by carefully following the steps defined by the SIM900 AT command manual.

-Include sub-sections that list out a problem and solution, such as:
+=== Locator Beacon ===
-=== My Issue #1 ===
+==== GPS ====
-Discuss the issue and resolution.
+After interfacing the GPS module with SJOne board the data received from the module was zero for both latitude and longitude. As the GPS module schematics showed different baud rate, we tried all the baud rate to check on which baud rate the data is received. After testing multiple time we decided to test in open field. In open field we started getting data at 9600 bps. The problem we faced here was that this GPS module was not for indoor usage. If the building is made of concrete and iron, then this GPS module won’t receive any data. For this GPS module, we had to be outside the building all the time since this GPS module was specifically designed for RC airplanes.

 The locator beacon is composed of four parts: a SJ One board, GPS and GPRS/GSM modules, and 5V 2.1A battery pack. On the SJ One board, the processor communicates with GPS and GPRS modules. Both modules have their own task. The following explains the features of each task and introduces a few main functions.
