Hi @Ad4mek !
I think that you don’t need to do much if you start from the Qorvo Nearby Interaction example.
The BLE part can be reused, there you will need to implement another way to exchange the UWB configuration between the DWM3001CDK and the Android app.
The function which starts TWR is “fira_niq_helper()”, in the function you will find the UWB configuration needed to start TWR, specially the “fira_param” structure passed as an argument to “construct_fira_param_from_config()”.
If you want to work exclusively with Android devices I recommend removing the niq library, the “anis” BLE service and modify the “qnis” service to do what I mentioned above.
Kind regards!
