A beginner guide for Sending data from android app to nrf52833BLE like sending a button status from android app to nrf

[noob_123]

I have seen webinar on YouTube where  NordicSemiconductor demonstrated a peripheral_hr that send simulated heart rate data from nrf52833 to nrf android app. But now I want to send data from an android app to the nrf52833. For instance I want to send status of a button (0 or 1) from android app to nrf52833. Is there any straight forward or simple resource available anywhere on internet to do this simple thing?

Hello,

You can look at peripheral LBS sample for sending data central to peripheral ( here is your DK) Bluetooth: Peripheral LBS — nRF Connect SDK 2.0.99 documentation (nordicsemi.com).

Thanks.

Hello,

You can start with ble_app_blinky which can be found in nRF5_SDK_14.0.0_3bcc1f7\examples\ble_peripheral. You can use another SDK if you want.

For the Android app, you can download the source code from here (NordicSemiconductor/Android-nRF-Blinky: nRF Blinky is an application developed targeting an audience of developers who are new to Bluetooth Low Energy (github.com)). Pls check the instruction mentioned in this app. 

Run the nRF code and open the app, you can play with on/off LED from the app to turn on/off LED in nRF development kit. Gluck!
