I need an Android app which read data from my device using AT commands behind the switch and store data in Excel sheet locally. The user will have the option to save data on the drive also.
Other device settings like device id, RTC time, updates.
With your budget I can make an application with an activity which can contain any amount of information and also the ability to save the flow of information from your device in a CSV that you have the ability to open it with Excel or I can also Make it stored in the local database app The advantage of CSV e that you can open in any application or operating system do not marry Excel think I like your project I've done many things with HC-05 and Arduino
