nRF54L15 Channel sounding FAE table issue

Hi,

Please consult https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/softdevice_controller/doc/channel_sounding.html#cs-supported-capabilities for the list of channel sounding capabilities. As you can see there, "Zero Transmitter Frequency Actuation Error" is labeled as supported -- this means that the nRF54L15 does not use or need an FAE table.

It may still use the remote device's FAE table if the remote device is from a different vendor who does not support this capability.

If the remote device needs the FAE table, calling bt_le_cs_read_remote_fae_table() is the correct way to obtain it.

This won't be properly implemented until NCS v3.0.0 I'm afraid. The status message seems to me to report that the file already exists which seems strange to me, but I don't think it makes sense debugging this as it is as of yet an unsupported feature.

Best regards,

Simon

Dear Simonr

Thank you very much for taking the time to reply.

Does this mean that FAE Table support is not available at the moment?

Because I have seen the function bt_le_cs_read_remote_fae_table, but the returned LE CS Read Remote FAE Table Complete Event is showing a 'Read Remote FAE Table failed with status 0x11' situation.

Thanks!

The calibration is something that will be done in SW and not shipped with the nRF54L15, but that's not ready from our side yet. If you want more information on when this can be expected you need to get in touch with the Nordic sales representative of your area. Let me know if you need help with that and I can reach out on your behalf.

Best regards,

Simon
