Hello!
My project requires sending data from my Arduino to the PC via Bluetooth low energy, to an external program. Is it possible to send such data via a Standard Bluetooth over serial interface (if there are better methods I am open to learn), and to create a python script that receives and processes said data? I must mention that I am a BLE newbie. Thank you in advance!
