CC2340R5: Is there any way to know 'Frequency drift' at application level?

Part Number: CC2340R5


Tool/software:

Hi Forum,

 I'd like to what is a 'frequency drift' the device having at application level (assuming the counterpart device has no drift) so that we can sort of implement some 'auto-tune' feature.

Regards

    Hi !

    As far as I know, there is no way to measure frequency drift during runtime. The datasheet for the CC2340R5 gives estimates of a frequency drift for the two internal clocks, but it cannot measure the drift, since if it could, it would auto-correct the clock drift it measures.

    Could you go into more details as to what is your use case ?

    Kind regards,
