Hi,

Thanks for the info. AoA and AoD info is not enough for my applications. I'm looking for a Nordic chip that is similar to TI's CC1350 which can give direct I/Q sample access.

Not limited to Bluetooth, do you have another chip that can do so?

The nRF52811, nRF52820, nRF52833 og nRF5340 can output IQ data. But not consciously, you can only get IQ data for the CTE (continuous tone extension) used for direction finding. There's more about this here: https://infocenter.nordicsemi.com/pdf/nwp_036.pdf

Hi,

Thanks for your reply. I'm not seeking a fully programmable transceiver. I would like to find a chip that gives access to the I/Q samples. Can you suggest if Nordic has one?

Best,

Lynn

No, sorry, that's not possible with nRF devices. You should look into SDR, software defined radio.
