If they support aoa and other ultra modern ble features they have to expose the raw IQ samples to a higher layer for dsp. That's not the same as full control

If they support aoa and other ultra modern ble features they have to expose the raw IQ samples to a higher layer for dsp. That's not the same as full control since you have to trigger it using gfsk anyway but there's other MCUs with granular radio control (RSL15 for example) that do allow for direct iq manipulation at the cost of skipping the hardware MAC which apparently everyone buys from CEVA as far as I can tell.
