Deck connection Python_script

[RubICS]

Hello Everyone,

I must admit that I am still quite a beginner. I was doing the Step_By_Step-Guide, given here: https://www.bitcraze.io/documentation/r ... commander/, and a problem has occurred. I don't understand why my deck, which I use, is not found. Can somebody help me out?

According to the client: I'm using the Deck: bcDWM1000.

What i did now is. I just changed the name of my Deck in the given script from the Step_By_Step-Guide:

And unfortunately my deck still can not be found. And i really need some advice, please.

Hi RubICS!

Let's see if we can figure this out! It seems like the code change you did should work, it should at least find the deck one thinks.

What is the output when you run that script? And what is the output if you run the basicparam.py example script?

Thanks
Jonas

First of all thank you very much jonasdn for replying.

The output when i run the script is: "no deck is detected" as it is written in the function.

And the Output of the basicparam.py example is this:

As I can see, my deck (bcDWM1000) is also found in that.

Thanks,

RubICS

Thank you!

Could you give me the complete code of the script that is not working?

Jonas

[RubICS]

Yeah for sure! Thanks for you patience.

The output is "Deck is NOT attached!"

Thank you very much.

Hi!

Could you post the entire script? Perhaps on pastebin.com ?

Hello Jonasdn,

i hope i did everything right. If so my code can be found here here: https://pastebin.com/SegtpYjL.

Thank you very much.

[jonasdn]

Thank you!

Am I right in understanding you do not get either of the:
print('Deck is attached!')
print('Deck is NOT attached!')

Outputs?

Could you try the following script? I modified it to ask for a parameter update.

Code: Select all

import logging
import sys
import time
from threading import Event

import cflib.crtp
from cflib.crazyflie import Crazyflie
from cflib.crazyflie.syncCrazyflie import SyncCrazyflie
from cflib.positioning.motion_commander import MotionCommander
from cflib.utils import uri_helper

URI = uri_helper.uri_from_env(default='radio://0/80/2M/E7E7E7E7E7')

DEFAULT_HEIGHT = 0.5

deck_attached_event = Event()

logging.basicConfig(level=logging.ERROR)

def take_off_simple(scf):
    with MotionCommander(scf, default_height=DEFAULT_HEIGHT) as mc:
        time.sleep(3)
        mc.stop()


def param_deck_flow(_, value_str):
    value = int(value_str)
    print(value)
    if value:
        deck_attached_event.set()
        print('Deck is attached!')
    else:
        print('Deck is NOT attached!')
        
 
if __name__ == '__main__':
    cflib.crtp.init_drivers()

    with SyncCrazyflie(URI, cf=Crazyflie(rw_cache='./cache')) as scf:

        scf.cf.param.add_update_callback(group='deck', name='bcDWM1000',cb=param_deck_flow)
        scf.cf.param.request_param_update('deck.bcDWM1000')


        if not deck_attached_event.wait(timeout=5):
           print('No flow deck detected!')
           sys.exit(1)

        #take_off_simple(scf)
