oLED Bluetooth Map

This App is part of a circuit DIY project. It generates a small openStreet Map from your location and sends every pixel to the Bluefruit UART (nRF mode) friend. A feather M0 firmware is added, too. You can use a HM10 (CC2541) bluetooth module, too! The circuit uses a arduino Pro mini and a SSD1331 oLED Display. I add a camera option to transfer a picture to the device. If you give the app notification access to read all notifications, it generates images with text, emoticons and app icon of the notification.

I add a small golang code: this code is a websocket server for you and it runs on port 65000. The App should be able to connect to it in your wireless network. Every picture is send to this server. The server save it as out.png

Privacy: This App caches the map on your phone and need access to your files. The files or your position is not send to me and everything is realy private :-D Ok, OpenStreet Map needs the position to generate the map. Ask them, what they are doing with that stuff :-/ The cam picture does not send it to a network (just bluetooth) or is stored permanently on your phone.
