We are building a data-logging application for Android phones (4.0+). The application will record information from multiple Bluetooth devices, the phone's internal sensors, and the camera to a set of files on external (microSD) memory. The GUI design choices are left to the developer.
The application will accept information from:
1) ScanTool OBDLink MX ([login to view URL]), an ELM327-compatible, Bluetooth enabled OBDII code reader (datasheet here: [login to view URL])
2) 2x Adafruit Bluefruit Micro ([login to view URL]), which will report comma-separated sensor values over UART (documentation here: [login to view URL])
3) Phone accelerometer and GPS data
4) Phone camera
A settings page will allow the user to set a master sampling rate, sensor sampling rate, sensor timeouts, camera direction (front/rear) and resolution, camera recording on/off, OBD II parameter list, and Bluetooth devices to be used. On the main page, the video feed from the camera should be shown and the most recent values from each sensor overlaid on the video or a separate graphic panel, so that the functionality of connected devices can be verified. A start/stop button will start and stop recording data to the microSD card.
When logging begins, a video file named with the date and time is created along with a similarly named .CSV file with the following columns:
System Unix time, Latitude, Longitude, OBD PID <name 1>, OBD PID <name 2>, … OBD PID <name n>, BLE Sensor 1 Value, BLE Sensor 2 Value, AccelX, AccelY, AccelZ
Each sensor will sample at the rate defined in the settings panel. The most recent data from each sensor will be recorded to the file at the master sampling rate, unless the most recent available data is older than the timeout for that sensor (in which case, ‘NaN’ is recorded).
The application must be robust against data outages and provide automatic reconnection to Bluetooth devices.
Hello Dear.
I have already build many apps like app you need.
I have experience with Radio spp, Video(Youtube, TV channel) , Spy app, Guard patrol system based on Nfc Read/Write , Location trace based on GPS, Routing app based on GoogleMp,Youtubevideo, JNI(FFMPEG,OPENVPN) , Responsible mobile site
Mobile Web.
Thanks
I have done 2 projects reading data from BLE device and reporting their values, and one complete sensor project to read from all available sensors of the android device. You can check my portfolio for Trouver app, ICUC Sensor app. PM me for further discsussion
Hi, dear.
I have a full experience of JNI, FFMpeg, Google API, WebService.
I have developed many apps for 5 years.
I have developed Social app with FB, G+, Chatting app(Iphone and Android).
I have developed E-Commerce app with payment, GPS location app, SIP call app, Youtube API app.
I have developed Spy app, Video Live Straming/Video Cutter app.
I have developed BLE device connection app(BLE printer app, Cahiser app using BLE).
I have developed Location Sharing Iphone app.
I have developed OpenVPN client for android.
If you give me this projects, i will satisfy you.
If you interested, please ping me.
Regards.
I want to discuss this project with you further, let me know the best suitable time for you to schedule the meeting, Feel free to message me at any time, i used to be online 14 hrs in a day on this website so probably you will get a quick response from my end.
