Overview
|
|
********
|
|
|
|
The BL654 Development Kit hardware provides
|
|
support for the Ezurio BL654 module powered by a Nordic Semiconductor nRF52840 ARM Cortex-M4F CPU.
|
|
|
|
It is also pin compatible with the BL654PA which adds a power amplifier. The "pa" variant provides
|
|
this compatibility. Use board ``bl654_dvk/nrf52840/pa`` to build for that target.
|
|
Bluetooth LE regulatory certifications obtained by Ezurio are not applicable to BL654PA variant.
|
|
It should not be used in commercial applications prior to re-certification being performed - please review with the Ezurio team at www.ezurio.com/contact

Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``bl654_dvk`` board configuration can be built, flashed,
|
|
and debugged in the usual way. See :ref:`build_an_application` and
|
|
:ref:`application_run` for more details on building and running.
|
|
|
|
Flashing
|
|
========
|
|
|
|
Follow the instructions in the :ref:`nordic_segger` page to install
|
|
and configure all the necessary software. Further information can be
|
|
found in :ref:`nordic_segger_flashing`. Then build and flash
|
|
applications as usual (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details).
|
|
|
|
Here is an example for the :zephyr:code-sample:`hello_world` application.
|
|
|
|
First, run your favorite terminal program to listen for output.
|
|
|
|
NOTE: On the BL654 DVK, the FTDI USB should be used to access the UART console.
|
|
|
|
.. code-block:: console
|
|
|
|
$ minicom -D <tty_device> -b 115200
|
|
|
|
Replace :code:`<tty_device>` with the port where the board nRF52 DK
|
|
can be found. For example, under Linux, :code:`/dev/ttyUSB0`.
|
|
|
|
Then build and flash the application in the usual way.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: bl654_dvk
|
|
:goals: build flash
|
|
|
|
Debugging
|
|
=========
|
|
|
|
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic based boards with a
|
|
Segger IC.
|
|
|
|
Testing Bluetooth on the BL654 DVK
|
|
***********************************
|
|
Many of the Bluetooth examples will work on the BL654 DVK.
|
|
Try them out:
|
|
|
|
* :zephyr:code-sample:`ble_peripheral`
|
|
* :zephyr:code-sample:`bluetooth_eddystone`
|
|
* :zephyr:code-sample:`bluetooth_ibeacon`
|
|
|
|
|
|
Testing the LEDs and buttons on the BL654 DVK
|
|
************************************************
|
|
|
|
There are 2 samples that allow you to test that the buttons (switches) and LEDs on
|
|
the board are working properly with Zephyr:
|
|
|
|
* :zephyr:code-sample:`blinky`
|
|
* :zephyr:code-sample:`button`
|
|
|
|
You can build and flash the examples to make sure Zephyr is running correctly on
|
|
your board. The button and LED definitions can be found in
|
|
:zephyr_file:`boards/ezurio/bl654_dvk/bl654_dvk.dts`.
