Scan example using Python library

Introduction

In this example, we're going to set up the dongle using the following Python script to scan for nearby Bluetooth devices.

This script will work on BleuIO Python library 1.2.0 or above

from bleuio_lib.bleuio_funcs import BleuIO
import time

# This is an example script showing how to scan for nearby bluetooth devices using BleuIO's Python library

# Creating a callback function for scan results. For this example we just prints out the result.
# Here you can add your code to parse the data.
def my_scan_callback(scan_input):
    print("\n\nmy_evt_callback: " + str(scan_input))

# Auto-Detect dongle
my_dongle = BleuIO()
# Registers the callback functions we created earlier.
my_dongle.register_scan_cb(my_scan_callback)

print("Scan for nearby Bluetooth devices using BleuIO Python Library!\n")
# Now we start scanning
# First we need to put the dongle in Central or Dual Gap Role
my_dongle.at_dual()

# We send in a timeout as a parameter for the at_gapscan() command. In that case it will scan for 3 seconds.
# Here we just set a three second sleep.
# Notice that all the scan data will be printed by our my_scan_callback() function.
resp = my_dongle.at_gapscan(3)
time.sleep(3)

print("\n--\n")
