Is there an official upstream Nordic UART android java class?

[Frank Sieber]

Hello,

I played around with the UART demo on the nRF52-DK and the belonging Android apps nRF UART v2.0, nRF Connect and nRF Toolbox. On PC side I used a serial console to see what's going on on the UART. Everything works well.

I also have startet do develop my own Android app. Referring to this the following question did arise:

Is there any official or upstream Nordic UART class for Android?

github.com/.../UartService.java

github.com/.../BluetoothLeUart.java

Or does Nordic only have registered the UART UUIDS and the rest of the Android side implementation is left to the Programmer?

Thanks in advance for your answer.

What do you mean by, "Official" ?

It's proprietary; certainly not anything from the Bluetooth SIG - so not "Official" in that sense

Sorry for using confusing words.

On infocenter.nordicsemi.com I have found some references to Adafruit, while reading the UART documentation and examples.

What is the better or more up to date code to start from:

github.com/.../UartService.java

or

github.com/.../BluetoothLeUart.java ?

Hi Frank,

The Nordic UART profile was made by us simply to show an example of using proprietary services and characteristic. There is nothing official at all. And you are free to use it anyway you like, or modify it the way you need.

We actually don't suggest user to use exactly same UUID for your application, because many other customers may use the same UUID from the example for other purposes.

The NUS profile didn't change much in the past few years, but if you want to have the most up to date reference please follow what we have in the ble_app_uart and ble_app_uart_c in the latest SDK. Our Android app developed based on the implementation in those examples.

Tha Adafruit implementation is a third party ones and we are not evolved with their implementation. It's most likely the same.
