Hello,
In page 9 of the above document STM is mentioning FFT - my question is - where can I find libraries for FFT, FIR etc. for BlueNGR-LP?
I'm trying to resolve the problem linking some external libraries and it seems to work but I'd be more confident if I could use dedicated and already tested libraries if they exist.
Regards,
Grzegorz

Thank you Piranha, I started with the below libraries
https://github.com/ARM-software/CMSIS/tree/master/CMSIS/Lib/GCC
but have nothing to share yet and still worrying if they are ok for BlueNRG-LP. That's why I asked if ST have already released any package of libraries dedictaed to BlueNRG-LP and including math transforms and filters functions. It seems they have not. I'll look closer at the newest you linked.

HI @Greg_​ ,
AS far as I know, there is nothing specific for BlueNRG-LP. This BLE SoC is based on a "standard" ARM cortexM0+, so basically you can reuse CMSIS Arm lib from ARM you already mentioned..

Sebastien.

Hi Sebastien,
Thanks for the answer - it would be nice to see them incuded in STSW-BNRGLP-DK :)
