 The implementation is based on :ref:`nrfxlib:bluetooth_coex` which is integrated into nrfxlib's MPSL library.

-
-Resources
-*********
-
-The Bluetooth 3-wire coexistence implementation requires exclusive access to NRF_TIMER1, in addition to the GPIO, GPIOTE and PPI resources listed in :ref:`nrfxlib:bluetooth_coex`.
-
-Enabling 3-wire coexistence and MPSL
-************************************
-
-Make sure that the following Kconfig options are enabled:
-
-* :kconfig:option:`CONFIG_MPSL_CX`
-* :kconfig:option:`CONFIG_MPSL_CX_BT_3WIRE`

-Configuring 3-wire coexistence
-******************************
-
-For more information about devicetree overlays, see :ref:`zephyr:use-dt-overlays`.
-A sample devicetree overlay is available at :file:`samples/bluetooth/radio_coex_3wire/boards/nrf52840dk_nrf52840.overlay`.
-The elements are described in the bindings: :file:`dts/bindings/radio_coex/sdc-radio-coex-three-wire.yaml`.
-
-Priorities and scanner mode can be configured or updated at run time.
-
-Role-based priorities
-*********************
-
-You can use a different priority for a session when requesting it, based on the session's role: advertiser, scanner, or being connected as central or as peripheral.
-To do so, use the HCI VS command :c:enum:`SDC_HCI_OPCODE_CMD_VS_COEX_PRIORITY_CONFIG`.
-Its parameters are described in  :c:type:`sdc_hci_cmd_vs_coex_priority_config_t`.
-
-Scanner request mode
-********************
-
-You can configure how the scanner requests coexistence sessions: either it requests a session as soon as it has received a valid access address, or it only requests a session before transmitting.
-To do so, use the HCI VS command :c:enum:`SDC_HCI_OPCODE_CMD_VS_COEX_SCAN_MODE_CONFIG`.
-Its parameters are described in  :c:type:`sdc_hci_cmd_vs_coex_scan_mode_config_t`.
-
-.. _ug_bt_coex_3w_sample:
-
-Sample application
-******************
-
-A sample application for 3-wire coexistence can be found at :file:`samples/bluetooth/radio_coex_3wire`.
