FAD Enabling in KW41Z

[ramyavlkr]

Hi Team,

We have developed custom FRDM-KW41Z board. It supports FAD antenna using SPDT RF Switch mini circuit. It
receives from both ANT_A/B and choose which one has better sensitivity. Here we are using Openthread source code.
I have gone through the MKW41Z512RM.pdf regarding FAD algorithm. I'm not getting clarity on the FAD enable.
Please help me to enable FAD(Any reference).

Thanks & Regards,
Ramya

Hi Ramya, I hope you’re doing well!

Unfortunately, the only documentation related to Fast Antenna Diversity in the KW41Z is section 44.6.2.12 of the KW41Z's reference manual, which can be found here.

We have one related reference design which shows how to use FAD with a Sky66112. Still, this is currently the only application note relating to Fast Antenna Diversity available right now.

I'm sorry for the inconveniences this may cause.

Please let me know if there's anything else I can help you with.

Best regards,

Sebastian
