oLED Bluetooth Map

Get position from smartphone, generates a map from osm, send map via UART bluefruit to a RGB display. App can take pictures and sends them, too! You can switch between nRF (bluefruit) or HM10 (CC2541) Bluetooth module. For feather M0 you need my SSD1331 lib (Adafruit based) and switch the app to nRF and slow.

If you garant the App notification access, it will send App icon and notification!

I add a golang websocket server - the app can send the image to that server. The server stores it as out.png file.

• Files: The osm part of the app caches the map on your phone. It does not read or touch any other files.
• Position: The osm part of the app needs your position to generate a map for this position.
• Network: The osm feature needs access to the internet to loads map tiles. You can use a private Websocket server and send the images (cam, notification, map) without encryption (!) to it.
• Bluetooth: The App sends data to your Do-It-Yourself Bluetooth device.
