IW61x: WCI2 and PTA external coexistence interfaces

[pierluigi_p]

Dear NXP team,

according IW611 / IW612 datasheets, these devices support both WCI-2 and PTA external coexistence interfaces.

1. Does the latest firmware support both these features ?
2. For IW612, PTA pins are the same used as SPI interface for 802.15.4 with OpenThread: how can PTA and SPI interface be simultaneously available ?

Thanks

Best Regards

Hi,

Could you please help me with the following information?

- What host are you using?
- OS version?

- What module are you using for IW612?

Hi @DanielRuvalcaba,

we are planning to use NXP Yocto Scarthgap 2.0.0 with iMX8MP and both IW611 (Murata Type 2DL) and IW612 (Murata Type 2EL) depending on customers requirement.

According NXP and Murata datasheets both the modules are suitable.

Please let me know if you need further details.

Thanks

Best Regards

Thanks for the info.

The datasheet states “…when 802.15.4 is used, WCI-2 is the only interface available for coexistence with an external radio.”

According to the NXP Wireless SoC Features and Release Notes for Linux, at this moment external coexistence is not supported for IW61x.

Let me double check if we have something about this.

Regards,

Daniel.

Hi @pierluigi_p ,

I'm sorry for the inconvenience. After crosschecking internally, seems the release notes have a typo.
IW61x does support external coexistence. I just raised a request to correct it.
