nRF52832 to mobile phone via BLE

[Sai Kiran]

Hi

Can anyone tell me which example in SDK to use to send data(a simple text message) from nRF52832 board to an Android Phone. I have nRF Connect and nRF Tools applications installed on the phone.

Thanks in advance.

Hi,

nRF Connect for Desktop has Linux support.

Hi Sai, 

The UART example is just an example of sending proprietary data over BLE. You don't need to use UART you can send anything you want with the example. 
Another example you can have a look is the blinky example. In that example we send only 1 byte. But you can modify it to send more data. 

You can download nrfBLinky app from google Play/App Store and source code is available on Github.

Hi

I have nrfBlinky and have programmed the softdevice. But, in the app, I am not able to find any connection. Any idea what could be the reason?

[Hung Bui]

You need to flash the ble_app_blinky in our nRF5 SDK, in addition to the softdevice.

I am confused between programming the softdevice and programming the board. What is the difference between them? I am using Segger Embedded Studio on Linux OS. Can you suggest how to program the softdevice and also the board?
