+title: NXP Bluetooth chips
+
+description:
+  This binding describes UART-attached NXP bluetooth chips.
+  These chips are dual-radio chips supporting WiFi and Bluetooth.
+  The bluetooth works on standard H4 protocol over 4-wire UART.
+  The RTS and CTS lines are used during FW download.
+  To enable power save mode, the host asserts break signal
+  over UART-TX line to put the chip into power save state.
+  De-asserting break wakes-up the BT chip.
