Transfer an array of numbers from NRF51822 to Android App

[Adnan Alvee]

Hi, I was able to successfully implement the tutorial titled "Testing and using a simple BLE application" available in the Tutorial section and transfer data from termite and the UART app and vice versa. For my project the thing I need was suppose I have an array of numbers like

int a[size] = [12,23,34,45];

I want to know how to transfer that data to the Android App as soon as I connect the NRF51 and the Android App. LIKE, exactly which part of the code should we edit for the NRF51 so that we can send data instantly as we connect the android instead of manually sending from TERMITE

Please help me or guide me to a tutorial. I think a lot of people are looking forward to this kind of tutorial because this is what typical user would want. We are not going to send data over terminal in a real world hardware application. To respective Nordic employees, please make this tutorial.

-Thanks

You can use Nordic Uart Service to transfer this kind of data easily. There should be NUS example in SDK. This is quite typical application, and quite easy to implement... You just have to receive the data and interpret it properly on your phone.

You have some information here - but this is not the exact project for your need. You have to modify it. Also, you have to make some android app to receive your data, obviously. but there should be some example uart app from nordics, you can use it for testing... I wouldn't expect nordics to give you the exact solution - their example just needs some basic tampering to fulfill your needs.
