The nRF Connect for Mobile is an application designed for Bluetooth Low Energy developers. It allows for scanning for BLE devices and communicating with them.
The nRF Connect for Android application requires Android version 4.3 or later and is available on Google Play or releases, in case Google Play is not available. We recommend to install the application using Google Play as it will get automatic updates.

nRF Connect supports the following DFU proptocols:
| Name | SDK | Supported Devices | Documentation |
|---|---|---|---|
| Legacy DFU | nRF5 SDK | nRF51, nRF52 | Link |
| Secure DFU | nRF5 SDK | nRF52 | Link |
| McuManager | nRF Connect SDK, Zephyr, Mynewt | nRF52, nRF53, nRF54, ... | Link |
The nRF Connect allows for executing XML scripts with test suites. Two sample XMLs for testing: the HRM-DFU sample and HRM-Scanning sample are available in documentation. They contains the full documentation of the currently available features. Copy those files and the test.bat script to your PC and run. Currently only Windows batch script is available, but adb commands can be called from Mac and Linux as well.
To start the test run the test.bat script:
test.bat [-d device_id] [-E KEY EXTRA] test.xmlor test.sh script:
./test.sh [-d device_id] [-E KEY EXTRA] test.xml You may specify key-value pairs in execution or inside the test using
<set name="KEY" value="VALUE" />
and then use them as ${KEY} (see the sample_test_hrm.xml).
Read mode about the test suites in the documentation.
Starting from version 4.4.0 it is now possible to automate operations using macros. Macros can be recorded, or imported from a XML file.
Read more about macros in the macros documentation.
