zero. If timeout is > 0, then the BLE radio will listen for advertisements until the specified
value in seconds elapses. If timeout < 0, then there's no timeout at all, and stop_scan()
needs to be called to cancel the scanning process.
Examples:
bluetooth.start_scan(10) # starts scanning and stop after 10 seconds
bluetooth.start_scan(-1) # starts scanning indefinitely until bluetooth.stop_sc

Example for getting
mac
import ubinascii
bluetooth = Bluetooth()
bluetooth.start_scan(20) # scan for 20 seconds
adv = bluetooth.get_adv() #
ubinascii.hexlify(adv.mac) # convert hexadecimal to ascii
bluetooth.get_advertisements()
Same as the
get_adv()
received.
