Convert DT_.*_GPIO_{CONTROLLER,PIN,FLAGS} -> DT_.*_GPIOS_{CONTROLLER,PIN,FLAGS) Used the following commands to make these conversions: git grep -l DT_.*_GPIO_CONTROLLER | xargs sed -i 's/DT_\(.*\)_GPIO_CONTROLLER/DT_\1_GPIOS_CONTROLLER/g' git grep -l DT_.*_GPIO_PIN | xargs sed -i 's/DT_\(.*\)_GPIO_PIN/DT_\1_GPIOS_PIN/g' git grep -l DT_.*_GPIO_FLAGS | xargs sed -i 's/DT_\(.*\)_GPIO_FLAGS/DT_\1_GPIOS_FLAGS/g' Signed-off-by: Kumar Gala <kumar.gala@linaro.org> |

.. _bluetooth-hci-spi-sample: Bluetooth: HCI SPI ################## Overview ******** Expose Zephyr Bluetooth Controller support over SPI to another device/CPU using the Zephyr SPI HCI transport protocol (similar to BlueNRG). Requirements ************ * A board with SPI slave, GPIO and BLE support. Building and Running ******************** In order to use this application, you need a board with a Bluetooth controller and SPI slave drivers, and a spare GPIO to use as an interrupt line to the SPI master. You then need to ensure that your Device Tree settings provide a definition for the slave HCI SPI device:: bt-hci@0 { compatible = "zephyr,bt-hci-spi-slave"; ... }; You can then build this application and flash it onto your board in the usual way; see :ref:`boards` for board-specific building and flashing information. You will also need a separate chip acting as BT HCI SPI master. This application is compatible with the HCI SPI master driver provided by Zephyr's Bluetooth HCI driver core; see the help associated with the BT_SPI configuration option for more information. Refer to :ref:`bluetooth-samples` for general Bluetooth information, and to :ref:`96b_carbon_nrf51_bluetooth` for instructions specific to the 96Boards Carbon board.
