Coexistence between 5340 and 3rd party Wifi chips via 1 wire protocol in Zephyr

[ProtoErikS]

We have a design using a nrf5340 with a Renesas Wifi chip,  That Renesas chip uses a 1 wire interface for Coexistence

We are using Zephyr 3.5.0 and have tried to follow https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/mpsl/doc/bluetooth_coex.html, by using the KConfig CONFIG_MPSL_CX_BT_1WIRE and its associated settings as the document calls out.  However, CONFIG_MPSL_CX_BT_1WIRE is only supported on the nRF52.

Is there an solution nrf5340 that we can follow?

Hi ProtoErikS,

You are right, one-wire coexistence interface is not currently supported on the nRF5340. You could try setting up a custom coexistence implementation.

Please refer to: Coexistence of short-range radio and other radios (nordicsemi.com)
