==== Update Drone Firmware ====
  - **Can only be done through the phone app!**
  - Download the newest Firmware in the App while still connected to the internet - before connecting to the drones wifi
  - Connect to the drones Wifi (TELLO-xxxx) without the extension module connected!
  - Under the app settings update firmware

==== Modify Extension Module Wifi AP ====
  - Connect only the extension module with a usb cable to your PC
  - Open the Mind+ software
  - Under Extensions (Bottom left) select "RoboMasterTT (ESP32)"
  - Then change the Wifi AP to something like below and press upload

==== HINTS ====
  * When the drone is set to STA / connect to router mode with the switch on the extension module, the propellers will start spinning once connected. If you want to stop the propellers simply lift the drone.

<code python>
from djitellopy import TelloSwarm

# Create a swarm with two Tello drones
swarm = TelloSwarm.fromIps(["192.168.2.122", "192.168.2.123"])

# Connect to the drones
print("Connecting to drones...")
swarm.connect()

#print("Battery levels:")
#for i, battery in enumerate(swarm.get_battery(), start=1):
#	print(f"Tello{i}: {battery}%")

# Change the LED colour of both drones
swarm.parallel(lambda i, tello: tello.send_expansion_command("led 255 0 0"))

# Execute commands as a swarm
swarm.takeoff()
swarm.parallel(lambda i, tello: tello.move_forward(50))

# Rotate only the second drone
swarm.tellos[1].rotate_clockwise(90)

# Change the LED colour of the second drone
swarm.tellos[1].send_expansion_command("led 0 255 0")

# Land all drones simultaneously
swarm.land()

print("Mission complete!")
