Week’s Task:Researching the possible platforms for the phone application as well as the functionality needed in the applicationResults:When trying to develop a phone application for a particular case, there is always a question of what platform to use. Whether to develop your application in android or ios is something to think about before starting to code. Before getting into which platform suits our project’s purpose, want to address the cross-platform sources. Cross-platform Sources: There are several platforms that have the ability to solve the issue of android vs ios by letting the programmers develop one coded program that can work on both platforms. Consider Titanium SDK for example. What Titanium aims to accomplish is to solve most of the problems related to writing separate codes for each device, by hiding all the gory implementation details behind a simple and well-defined javascript API. On top of that, it will (more or less) compile your javascript to a different language (objective-c for iOS, Java for Android and soon Blackberry) so you can deploy your application to multiple targets with no changes to your code. Everything sounds good with titanium; however, it has major problems that we need to address. The more complex your applications become, the more often you encounter some weird glitches. Your app starts to crash, seemingly at random because of memory starvation. When your application reaches a certain level of complexity, those issues will become evident – in the form of sudden, unavoidable crashes. This leaves you stuck with a frail, buggy application that is ready to blow up at every click… and there’s nothing you can do about it except for a complete rewrite in objective-c or java. Also, for the purpose of using BLE, Titanium SDK is not a good fit. Android Vs. iOS: For our project use case, I think android-base application would be the optimal solution for the following reason: Android phones are widely used throughout the world. Android-based application uses Java programming language which is very popular and useful. Android 4.3 (API 18) introduced built-in platform support for BLE. This allows Android apps to communicate with BLE devices that have low power requirements, such as proximity sensors, heart rate monitors, fitness devices, and so on. We can test the application by uploading it into stores for free. While iOS apps costs money to be uploaded into apple store. iOS uses Objective-C programing language which is not popular in the programing world. To develop an ios application, you need a MAC computer which I don’t have. After developing an android application and get it working, we can make changes to get it working in Objective-C in order to implement it in ios systems. Engineer’s Name: Deleon A.

Research Hands Free Soap Dispensers Results: The Automatic soap dispenser used at SDSU is the Georgia Pacific 52053 The only location I could find it at was the bathrooms in the west commons building, all other building have manual dispensers. it can be bought online for $50 dollars on amazon.com if bought from granger it is $130. It operates on 4 D-cell batteries most likely in series and parallel to get the voltage up to 3vdc and give more amp hours. It has 2 preset dispensing amounts .4 ml and .7 ml and has a 1200ml refill. That gives about 1700 or 3000 dispenses per cartridge. Gojo TFX makes a hands free dispenser also that uses 3 C-cell batteries and a 1200 ml refill. It is $30 online and $51 on Granger. There are other cheaper hands free soap dispensers out on the market. Most are battery powered at around 3vdc there are others that are powered by 120vac which we decided not to use. Engineer’s Name: Joel Rendon Week’s Task: Research BLE’s Results: This week, my main focus was to look up possible BLE’s that could be integrated into our beacon design. There is an option of trying to purchase a BLE and connect it with a microcontroller but it is better for the BLE to be Soc. There are a few BLE’s out there but I broke down the search to two possible BLE’s that can be used to this project.
After doing research, I believe that the best choice is definitely picking the CC2540. The advantage with the Nordic BLE is the use of the Cortex M0 microcontroller, which we have used in the past. However, as an engineer, sometimes we have to get out of the comfort zone and look at what is best for this project. What makes the CC2540 BLE a better competitor is that it provides a better ease to communicate with sensors. The following links contains the data sheet for both of these BLE’s: CC2540:
