Hi,
I am struggling with I2S. While I was debugging my I2S data handler function, I found something interesting. I copy one element from a uint32 buffer into a (static...
Hello all!
Simple question: What is a SNR value for BT LE? I read 20 dB are OK, but I would like some sources/informations to back this number up.
Thanks!
Cheers...
