Hello all, I am undergoing a project in which I am limited to using an Arduino nano or smaller (so I went with Arduino nano). I want to record a speech of a max of 5-15 seconds using Arduino nano iot and then send it to my android phone. I heard that there is a way of using Bluetooth classic on nano iot but I'm not sure. Do you all have any faster method for this problem? or should I use wifi? Also, if you all can recommend a small microphone that can satisfy my needs that would be great!
