Description

nRF Blinky is an application developed targeting an audience of developers who are new to Bluetooth Low Energy. This is a simple application with two basic features.
- Scan and connect to any nRF5 DK containing the Nordic Semiconductor’s proprietary LED Button Service.
- Turn on/off LED 1 on the nRF DK
- Receive Button 1 press event from a nRF DK on the nRF Blinky Application.

The source code for this application is available on GitHub on the following link:

https://github.com/NordicSemiconductor/Android-nRF-Blinky

Note:
- Android 5 or newer is required.
- Location permission is required on devices running Android 5 - 11. This app will not use the location information in any way. Starting from Android 12 the app is requesting Bluetooth Scan and Bluetooth Connect instead.

Recent changes:
This is a major update of the app. The Bluetooth LE connectivity was migrated from the old Java-based BLE library to Kotlin BLE Library.

The UI and UX was also improved. The connection screen now shows Click and Long Click events and allows to "bind" LED state with the button state.

Check out all the changes on GitHub.

Note:
Due to the current minimum required version of underlying libraries, the app supports now devices running Android 6.0 Marshmallow or later.

It does the job of testing the ble_blinky app, not sure why they call it blinky though as it doesn't blink!!! :)

Doesn't work with nRF DK board PCA10040, batch 2018.24, says that the required characteristics were not found when the board itself briefly switches from LED1 off + LED2 on to indicate the attempted connection... I was hoping it would be easier to develop in the nRF ecosystem, but I'm really not having a good experience ☹️

★☆☆☆☆ Paresh Patil · Nov 22, 2018

App is not connecting to BLE device after update. Yes similar issue. Okay I can continue on GitHub issue.
