FFT with CC2540

Hello, I'm searching some literature reference / application note  reporting FFT implementation with CC2540 ( with TI 8051).

the FFT is needed in order to find low harmonics of AC grid voltage (50 Hz in Europe) and therefore it should not be very computational intensive, the sampling frequency is a few kHz and the FFT should be performed on 128 or at most 256 samples, so I think it should be affordable even using an 8 bit microcontroller as TI 8051.

    We at TI have never tried this before. A suggestion I would have for you would be to post this questions in the ZigBee and SimpliciTI forums as well. The communities for those forums are much larger, since those SW stacks have been around longer than BLE. The CC2530 has an identical MCU to the CC2540, so someone may have done this already.
