| CYW43xxx Connectivity that uses Zephyr's Bluetooth Host Controller Interface UART |
| driver. |
| |
| Example of enabling CYW43xxx device: |
| |
| &uart2 { |
| status = "okay"; |
| current-speed = <115200>; |
| |
| /* HCI-UART pins*/ |
| pinctrl-0 = <&p3_1_scb2_uart_tx &p3_0_scb2_uart_rx |
| &p3_2_scb2_uart_rts &p3_3_scb2_uart_cts>; |
| pinctrl-names = "default"; |
| |
| /* HW Flow control must be enabled for HCI H4 */ |
| hw-flow-control; |
| |
| bt-hci { |
| status = "okay"; |
| compatible = "infineon,cyw43xxx-bt-hci"; |
| bt-reg-on-gpios = <&gpio_prt3 4 (GPIO_ACTIVE_HIGH)>; |
| |
| fw-download-speed = <3000000>; |
| }; |
| }; |
| |
| NOTE1: The UART bus speed (current_speed) for zephyr_bt_uart should be the same |
| as the default baudrate defined in CYW43xx firmware (default 115200). |
| |
| NOTE2: Use fw-download-speed and hci-operation-speed properties to configure UART |
| speeds for firmware download (fw-download-speed) and HCI operation |
| (hci-operation-speed). |
| If hci-operation-speed or fw-download-speed are not defined in bt-hci node, |
| cyw43xx driver will use bus/current-speed as default speed. |
| |
| NOTE3: CYW43xxx requires fetch binary files of BT controller. To fetch binary blobs: |
| west blobs fetch hal_infineon |
| |
| compatible: "infineon,cyw43xxx-bt-hci" |
