How to receive data through nus

[yifan hao]

I've been working on a project, which requires data transmitted through ble to cell phone app. The user could acquire the data from the sensor when he sends a specific string using cell phone app to the device through ble. I've been reading the example here

Does anyone know which part of the code needs to be modified in order to implement the feature I want? Besides, what's the relationship between ble and uart in nRF51822. Thanks in advance!

Lot's of information in the forums on this by searching for NUS. This question has been asked so many times.

As to your second question, are you asking the relationship between Bluetooth Low Energy and a UART? Or do you mean NUS and UART? NUS is Nordic's radio (via Bluetooth Low Energy) equivalent of a UART which normally is via wired connection.
