Hi all just been thrown a nice curve ball.
I have been asked to use tello edu to teach python coding.
What is the bare minimum code I need for python to connect to a drone and get it to take off, then land.
I can then add bits and pieces later on into between and then talk about variables and loops.
I had a quick look at the Python code lessons but got a bit confused on what to take out and ended up spending ages trying to debug my Frankenstein code
Did you go through DroneBlocks curriculum yet. I was able to get started with Python coding using thr curriculum.
Yep I went through the programme and got drones working just want to strip out everything and just want drone to connect take off and land.
I edited the code to what I thought was right but got lots of errors, when correct others appeared and got frustrating
Oh ok. Can you put your code here. Let’s have a look at it.
import socket
import threading
import time
tello_address = (‘192.168.10.1’, 8889)
local_address = (’’, 9000)
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.bind(local_address)
def send(message, delay):
try:
sock.sendto(message.encode(), tello_address)
print("Sending message: " + message)
except Exception as e:
print("Error sending: " + str(e))
time.sleep(delay)
def receive():
while True:
try:
response, ip_address = sock.recvfrom(128)
print("Received message: " + response.decode(encoding=‘utf-8’))
except Exception as e:
sock.close()
print("Error receiving: " + str(e))
break
receiveThread = threading.Thread(target=receive)
receiveThread.daemon = True
receiveThread.start()
send(“command”, 3)
send(“takeoff”, 5)
send(“land”, 5)
print(“Mission completed successfully!”)
sock.close()
Dont worry I have sorted it ready to rock and roll
Would you mind sharing your final solution so that others can benefit? Interested in seeing what you came up with!
It was the same code as above I was messing around with spaces and tabs when not needed.
Can see it running here
Bravo! I just learned about QPython from your video. We have been using Pythonista for iOS. Thanks for sharing.
The power of sharing it is a great little app and for me it is a game changer and for the kids I teach. I wonder if we can get it to swarm which is my final aim
I went for the OL version as was aimed more at learning and the 3L was more advanced. Always use Python 3 not python 2. I was sitting on the bus coding on phone love it
We’ll call you the “Mobile Coder”
Just FYI we have some swarm sample code here:
There will be a few challenges to get this set up but happy to assist. If you’d like to chat about it please crate a new post so we keep things clean. Thanks.
