The approach is quite different to the original way and the documentation –as well as information on devices supporting it– does not entirely sound promising, for instance, “actual rate is expected to be between 55% to 220% of nominal rate” – it appears to be optimised for more efficiency rather than higher rates.
It is on an ever-growing list of possible improvements with no plans when it could get be integrated. Certainly, one of the more interesting entries, however, also one of those that require some research to implement it on a reasonable level.
Thanks for your answer on this.
I would be very interested in such an feature, as the nominal frequency is around 800Hz, and many real world applications require more the 1 kHz, i.e. performing classifications based on FFT.
The standardisation of the sensor samples are easily performed for people who have basic understanding of sensors, so there would be no need to acquire this information if necessary.
Actually I would expect that the method is not hard to implement, there is rather the question how many smartphones fulfill the requirements, but I would say a simple if condition or a query if it is supported would be enough.
Nevertheless, I m very impressed about the Phyphox app anyway
