The Bluetooth® EnOcean sample demonstrates the basic usage of the Bluetooth EnOcean library.
The sample supports the following development kits:
The sample also requires at least one supported EnOcean device.
The sample supports up to four devices at a time with one development kit.
The EnOcean sample sets up a basic Bluetooth observer for both EnOcean switches and sensors.
The observer device forwards incoming advertisements to the EnOcean library for processing. The application receives events from the EnOcean library through callbacks, and prints the outcome to the console. The LEDs of the kit also respond to button presses from an EnOcean switch.
The following LEDs are used by this sample:
- LED 1 and LED 2:
At the end of commissioning, blink four times to indicate that a new EnOcean device has been commissioned.
After commissioning, indicate whether a button is pressed on a commissioned light switch device.
If you are using EnOcean switches with a single rocker, toggling the rocker is indicated on LEDs 2 and 4.
- LED 3 and LED 4:
Indicate the On/Off state of each button channel.
Building and running
This sample can be found under
samples/bluetooth/enocean in the nRF Connect SDK folder structure.
To build the sample with Visual Studio Code, follow the steps listed on the How to build an application page in the nRF Connect for VS Code extension documentation. See Building and programming an application for other building and programming scenarios and Testing and debugging an application for general information about testing and debugging in the nRF Connect SDK.
After programming the sample to your development kit, complete the following steps to test it:
Commission one or more EnOcean devices. The LEDs will blink when each of the devices has been successfully commissioned.
Connect the kit to the computer with a USB cable. The kit is assigned a COM port (Windows) or ttyACM device (Linux), which is visible in the Device Manager.
Connect to the kit that runs this sample with a terminal emulator (for example, PuTTY). See How to connect with PuTTY for the required settings.
Depending on the EnOcean devices you commissioned:
If you commissioned a light switch, press any of its buttons or toggle the rocker to control the LEDs. The LEDs turn on and off as detailed in User interface, and the received values are printed to the console.
Sensor devices will automatically start reporting their sensor values to the application. The values are printed to the console.
The following code sample shows the light switch output when Button 4 on the EnOcean device was pressed and released:
EnOcean button RX: ba:15:00:00:15:e2: pressed: 0 0 0 1 EnOcean button RX: ba:15:00:00:15:e2: released: 0 0 0 1
The following code sample shows the sensor device output:
EnOcean sensor RX: bb:00:00:00:00:e5: Occupancy: true Light (sensor): 85 lx Energy level: 92 % Light (solar cell): 365 lx
This sample uses the following nRF Connect SDK libraries:
In addition, it uses the following Zephyr libraries:
