To install for current user:\n\n.. code-block:: shell\n\n    pip3 install adafruit-circuitpython-bluefruitspi\n\nTo install system-wide (this may be required in some cases):\n\n.. code-block:: shell\n\n    sudo pip3 install adafruit-circuitpython-bluefruitspi\n\nTo install in a virtual environment in your current project:\n\n.. code-block:: shell\n\n    mkdir project-name && cd project-name\n    python3 -m venv .env\n    source .env/bin/activate\n    pip3 install adafruit-circuitpython-bluefruitspi\n\nUsage Example\n=============\n\n.. code-block:: python\n\n    # A simple echo test for the Feather M0 Bluefruit\n    # Sets the name, then echo's all RX'd data with a reversed packet\n\n    import time\n    import busio\n    import board\n    from digitalio import DigitalInOut\n    from adafruit_bluefruitspi import BluefruitSPI\n\n    spi_bus = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)\n    cs = DigitalInOut(board.D8)\n    irq = DigitalInOut(board.D7)\n    rst = DigitalInOut(board.D4)\n    bluefruit = BluefruitSPI(spi_bus, cs, irq, rst, debug=False)\n\n    # Initialize the device and perform a factory reset\n    print(\"Initializing the Bluefruit LE SPI Friend module\")\n    bluefruit.init()\n    bluefruit.command_check_OK(b'AT+FACTORYRESET', delay=1)\n\n    # Print the response to 'ATI' (info request) as a string\n    print(str(bluefruit.command_check_OK(b'ATI'), 'utf-8'))\n\n    # Change advertised name\n    bluefruit.command_check_OK(b'AT+GAPDEVNAME=BlinkaBLE')\n\n    while True:\n        print(\"Waiting for a connection to Bluefruit LE Connect ...\")\n        # Wait for a connection ...\n        dotcount = 0\n        while not bluefruit.connected:\n            print(\".\", end=\"\")\n            dotcount = (dotcount + 1) % 80\n            if dotcount == 79:\n                print(\"\")\n            time.sleep(0.5)\n\n        # Once connected, check for incoming BLE UART data\n        print(\"\\n *Connected!*\")\n        connection_timestamp = time.monotonic()\n        while True:\n            # Check our connection status every 3 seconds\n            if time.monotonic() - connection_timestamp > 3:\n                connection_timestamp = time.monotonic()\n                if not bluefruit.connected:\n                    break\n\n            # OK we're still connected, see if we have any data waiting\n            resp = bluefruit.uart_rx()\n            if not resp:\n                continue  # nothin'\n            print(\"Read %d bytes: %s\" % (len(resp), resp))\n            # Now write it!\n            print(\"Writing reverse...\")\n            send = []\n            for i in range(len(resp), 0, -1):\n                send.append(resp[i-1])\n            print(bytes(send))\n            bluefruit.uart_tx(bytes(send))\n\n        print(\"Connection lost.\")\n\nContributing\n============\n\nContributions are welcome! Please read our `Code of Conduct\n<https://github.com/adafruit/Adafruit_CircuitPython_BluefruitSPI/blob/master/CODE_OF_CONDUCT.md>`_\nbefore contributing to help this project stay welcoming.\n\nBuilding locally\n================\n\nZip release files\n-----------------\n\nTo build this library locally you'll need to install the\n`circuitpython-build-tools <https://github.com/adafruit/circuitpython-build-tools>`_ package.\n\n.. code-block:: shell\n\n    python3 -m venv .env\n    source .env/bin/activate\n    pip install circuitpython-build-tools\n\nOnce installed, make sure you are in the virtual environment:\n\n.. code-block:: shell\n\n    source .env/bin/activate\n\nThen run the build:\n\n.. code-block:: shell\n\n    circuitpython-build-bundles --filename_prefix adafruit-circuitpython-bluefruitspi --library_location .\n\nSphinx documentation\n-----------------------\n\nSphinx is used to build the documentation based on rST files and comments in the code. First,\ninstall dependencies (feel free to reuse the virtual environment from above):\n\n.. code-block:: shell\n\n    python3 -m venv .env\n    source .env/bin/activate\n    pip install Sphinx sphinx-rtd-theme\n\nNow, once you have the virtual environment activated:\n\n.. code-block:: shell\n\n    cd docs\n    sphinx-build -E -W -b html . _build/html\n\nThis will output the documentation to ``docs/_build/html``. Open the index.html in your browser to\nview them. It will also (due to -W) error out on any warning like Travis will. This is a good way to\nlocally verify it will pass.",
