Hi @alliv ,

If i use “DWM3001CDK-DW3_QM33_SDK_CLI-FreeRTOS_0_1_1.hex” binary, can i run TWR scenario above? does qorvo share TDoA example for DWM3001C, i couldnt find TDoA example on qorvo website.

Regards,
Huseyin.

Example commands below:
Initiator in the scenario below can be the tag.
Responders are the anchors.

About TDoA, Qorvo does not provide an example as part of the SDK0.1.1.
