These chips11 are dual-radio chips supporting WiFi and Bluetooth. The bluetooth12 works on standard H4 protocol over 4-wire UART. The RTS and CTS lines13 are used during FW download. To enable power save mode, the host14 asserts break signal over UART-TX line to put the chip into power save15 state. De-asserting break wakes up the BT chip.16 17maintainers:18 - Neeraj Sanjay Kale <neeraj.sanjaykale@nxp.com>19 20properties:21 compatible:22 enum:23 - nxp,88w8987-bt24 - nxp,88w8997-bt25 26 fw-init-baudrate:27 $ref: /schemas/types.yaml#/definitions/uint3228 default: 11520029 description:30 Chip baudrate after FW is downloaded and initialized.31 This property depends on the module vendor's32 configuration.33 34 firmware-name:35 maxItems: 136 37required:38 - compatible39 40additionalProperties: false41 42examples:43 - |44 serial {45 bluetooth {46 compatible = "nxp,88w8987-bt";47 fw-init-baudrate = <3000000>;48 firmware-name = "uartuart8987_bt_v0.bin";49 };50 };51
