Hi Ricardo,
I am seeing the same issue when doing channel sounding evaluation with KW45B41Z-LOC boards. There is no "Wireless Localization" Middleware when building/downloading the SDK.
Can you please send me the SDK with wireless localization middleware and the wireless_ranging example/project? Really appreciate if you can send me "AN13974 - Bluetooth Low Energy Localization Application Note" as well.
Thank you!
