PiDroid A Simple Application that allows a Raspberry Pi (raspberian) to communicate with an Android device (4.0+). PiDroid will be used to take pictures or video and store it on a RaspberryPi and in turn stream Pictures and Video onto a Raspberry Pi. This will be part of a Museum Piece where participants will record video and pictures on how "skin" has affected their worldview.
This project is an extension of Public Payphone [http://leimertphonecompany.net] which currently can record and play audio and upload pictures to Twitter. The Pi currently listens to dialpad presses and uses these to trigger the above activities. Part of the GPIO dialpad code is at [https://github.com/sabzo/piphone-cam/blob/master/tommyCam.py]
This project can utilize two different types of WiFi connection methods: Infrastructure and WifiDirect. Infrastructure is the traditional WiFi access point. WiFi direct connects without using an AccessPoint.
Infrastructure- Raspberry Pi (Pi) creates 'infrastructure' Access Point and broadcasts Access Point
- Pi creates a Web Server (Flask in this case) and serves media to connected devices (mobile/desktop)
- Pi saves user content in SQLite DB
Wifi Direct- Raspberry Pi (Pi) advertises itself as P2P enabled and specifically requests to be a Group Owner upon connection.
- Android app detects nearby Pi displays connection name on Screen
- Android triggers connection by a Click event, pbc (PBC). This ensures no specific key code is needed
- Android takes pictures and stores them on Pi
- Android can stream pictures and video from raspberry pi
- Android can stream video (Miracast) to nearby WiFi enabled devices
- Ensure that the WiFi device, usually wlan0 on Linux, has a Realtek chip.
This program relies heavily on
iwpriv wlan0 p2p_setwhich has custom realtek commands. https://rtl8192cu.googlecode.com/hg-history/bdd3a2265bdd6a92f24cef3d52fa594b2844c9c1/document/RTK_Wi-Fi_Direct_Programming_guide.pdf
