BOOSTXL-AOA: How does AOA location work using a 250kHz signal?

I'm confused how the BOOSTXL-AOA kit generates and uses the 250kHz signal for angle measurement.

Dosesn't the signal delay depend on the carrier (2.4GHz) frequency? How is the 250 KHz utilized?

thanks

Hi Michael,

The sigle tone is transmitted at the carrier frequency + 250 kHz. (250 kHz is used as a nickname for this pat of the packet.) Please see the Packet Format section of the Angle of Arrival chapter ( dev.ti.com/.../localization-index.html )
