 == Conclusion ==
-From this project, we gained a better understanding on how FreeRTOS, Uart, Bluetooth communication works. We also learned how to build a simple Android Application associated with Bluetooth. Our project is pretty simple, but this is my (TIAN) first hardware/software hybrid project, where we had to start from the beginning, design, build and code, and finally test. We were stuck several times throughout the project, but with Preet's help, we came through. It is a good experience, and a reference to both of our future projects.

Our project is pretty simple, but this is my (TIAN) first hardware/software hybrid project, where we had to start from the beginning, design, build and code, and finally test. We were stuck several times throughout the project, but with Preet's help, we came through. However, we did not do a good job managing the time, and in the end we were not able to implement some of of features that we wanted in the first place, such as sound warning at a close distance or radar view of the distance. But It is a good experience, and a reference to both of us in our future projects.

	For the Android App, Our design is really simple: the app is going to check if bluetooth on your Android phone is on, if not, it will prompt the user to turn it on; then it is going to start continuously receiving string that is sent from the board via bluetooth, and then parse the string, check for end of line '/r/n', and then display the string at the center of the screen in TextView field, saying how far is your car is to the wall in cm. We pre-loaded the MAC address of the bluetooth module into the app, so we don't have to manually connect to it everytime. But this requires that the bluetooth module is paired with your phone already, and bluetooth permission is granted to the app.		For the Android App, Our design is really simple: the app is going to check if bluetooth on your Android phone is on, if not, it will prompt the user to turn it on; then it is going to start continuously receiving string that is sent from the board via bluetooth, and then parse the string, check for end of line '/r/n', and then display the string at the center of the screen in TextView field, saying how far is your car is to the wall in cm.
