Built an Android App

I would like to have a native android app developed for an embedded project, with basic functions such as Communication Via Bluetooth, (For mode changes in the system, data retrieval, and OTA update delivery). Also a UI where the retrieved data can be visualized as a plot. Detailed requirement: 1. Basic Optional App Security (Device level only) 2. A dashboard which displays data received on last synch from the embedded system via Bluetooth, the mode in which the System is now running (For instance Mode 1, Mode 2) 3. There will be multiple parameters the user can send to the embedded system using Bluetooth while connected to the system. 4. OTA Payload delivery to the embedded system – User should be able to check if any new firmware is available through a request to our server, and if there is a new version, the app should be able to download it automatically (Few bytes or Kb of data). 5. The app should be capable of pushing the new firmware to the embedded system when it connects through Bluetooth the next time. 6. A clean and interactive UI • Minor changes to the requirements may happen during developmental phase as every project evolves. • Complete Source code with comments preferred for avoiding longer project duration. Contact me for any further clarification,
