NFC: Launch App
The NFC Launch App sample shows how to use the NFC tag to launch an app on the polling smartphone. It uses the NFC Data Exchange Format (NDEF) library.
Requirements
This sample supports the following development kits:
Hardware platforms |
PCA |
Board name |
Build target |
|---|---|---|---|
PCA10095 |
|
||
PCA10040 |
|
||
PCA10056 |
|
The sample also requires a smartphone or a tablet. You need to have the nRF Toolbox app installed for iOS devices.
Overview
When the sample starts, it initializes the NFC tag and generates an NDEF message with two records that contain the app Universal Link and Android Application Record. Then it sets up the NFC library to use the generated message and sense the external NFC field.
The only events handled by the application are the NFC events.
User interface
- LED 1:
Indicates if an NFC field is present.
Building and running
This sample can be found under samples/nfc/record_launch_app in the nRF Connect SDK folder structure.
See Building and programming an application for information about how to build and program the application and Testing and debugging an application for general information about testing and debugging in the nRF Connect SDK.
Testing
After programming the sample to your development kit, complete the following steps to test it:
Touch the NFC antenna with the smartphone or tablet and observe that LED 1 is lit.
Observe that the smartphone or tablet launches the nRF Toolbox application.
Move the smartphone or tablet away from the NFC antenna and observe that LED 1 turns off.
Note
Devices running iOS require the nRF Toolbox app to be installed before testing the sample. Devices running Android open Google Play when the application is not installed.
Dependencies
This sample uses the following nRF Connect SDK libraries:
In addition, it uses the Type 2 Tag library from sdk-nrfxlib:
The sample uses the following Zephyr libraries:
