Sailing ble App data logging and telemetry

Realization of a nautical telemetry platform (Web Portal + Mobile App (Android + IOS)) can process information from specific nautical device - using BLE (Bluetooth low energy) and NMEA protocol (nmea 0183) - Graphing the data on app and web portal. The application that will run on smartphones, tablets, smartwatch, will have to be responsive client; When connected to the nautical device (manufactured by us) will display navigation data in textual form and graphical form with a good quality gauge; the display data and graphically display are: • BS-COG (boat speed), (live, min, average, max) • AWA (apparent wind angle) • AWS (apparent wind speed) (live, min, average, max) • AWD (apparent wind direction) • TWD (true wind direction) • TWA (true wind angle) • TWS (true wind speed) (live, min, average, max) • COG (Course Over Ground) • HDG (heading) • Pitch (live, min, average, max) • Roll (live, min, average, max) • Drift • VMG (velocity made good) • atmospheric pressure (live, min, average, max) • temperature (live, min, average, max) • GPS position (text & map) • GPS quality • Waypoint All data, some coming from the device, more calculated, will have to be registered and obviously displayed on the device (data logging), you will be sent live on in the cloud platform (telemetry). They can be set alarm thresholds on various measurements. They may be fetched data from third-party web service, for example: • Conditions and marine forecast • Terms of boat traffic Each user must authenticate the app in order to use the services of web portal The web portal will allow the display of its navigation data synchronously (live telemetry) or asynchronous; The web portal will allow users to create groups of boats and / or navigation groups; a master user, for example, can create a navigation group, where inside you can invite other members (slave); The master user can then view your browsing data data and those of the groups operated by him; the master user you can see your boat and that of members of their own groups directly on the portal with type nautical map display.
