@robolink_leila Hello,
I have used time.sleep() before, but doesn't help a lot before. But, I will test this again after refreshing the connection.
However, currently it is solid green (tail LED) when a battery is plugged in

Even reset doesn't work

I setup the 30 min tech support this afternoon, but no show.
Thank you.
@ixmclean One more question:
As you can see from a video, when a drone lands on a floor using land( ), it hit a ground hardly. I guess this may cause a problem of a motor (position).
So, is there way for very soft landing using library?

(see the last part of video for landing)
Thank you
@ixmclean Hello,
Yes, sometimes, the communication drops to the drone (1 in 6 times is a rough guess) I've made it a habit to unplug the BLE cable, and re-seat the CoDrone Battery to ensure a fresh connection most of the time.
--> Mine is almost every time of the communication drop. Anyway, your suggested workaround (i.e., reconnect BLE and battery every try) is working so far (I tested successfully 4 times in a row)
However, the first case of my failures (in my previous note) still happened to me. Even after successful landing, the right front motor is now running. So, my another question is:
Do you have any library to test a specific motor without takingoff nor calibration?
Now, whenever the motor is not working, I run calibrate( ) with holding a drone by left hand, and adjusting motor position in a arm until running. Then, re calibrate() -> run the code.
This is not convenient also not safe (a couple of times hit my fingers). Any suggestions?
Thank you in advance.
@ixmclean Hello,
Thank you so much for your suggestion.
Also, from time to time, I need to reconnect a battery to be paired.
@ixmclean Thank you so much for your quick reply. I just figure out the problem.
I have run the program using terminal python script as below:
i) MacOS -> Start terminal
ii) at command line:
Sometimes, command line interpreter looks like lose some data (not sure, there might be byte data...), which caused the problem.
However, using Jupyter is fine.
So, my question is :
"What are suggested IDE for CoDrone programming rather than Jupyter?"
During the competition, some of students are not familiar with Jupyter, so I'd better know what are the suggested IDE.
Also, any work around of the problem using command line script programming?
Thank you in advance.
This is Jeongkyu Lee at University of Bridgeport and testing a demo unit for KMSO in NY. Here is issues of demo unit:
========= a2.py ==========
import CoDrone
from CoDrone import Direction
drone = CoDrone.CoDrone() # easier to type drone
drone.pair(drone.Nearest) # pairs to nearest drone
drone.takeoff() # takeoff for 2 seconds
drone.hover(3) # hover for 3 seconds
drone.go(Direction.FORWARD, 1, 30) # moves the drone forward for 2 seconds at 30% power
#drone.go(LEFT, 1, -30) # moves the drone left for 2 seconds at 30% power
drone.go(Direction.BACKWARD, 1, -30) # moves the drone backward for 2 seconds at 30% power
#drone.go(RIGHT, 1, 30) # moves the drone right for 2 seconds at 30% power
====== a3.py ==========
import CoDrone
drone = CoDrone.CoDrone()
drone.pair() # pairs to previous drone
drone.takeoff() # takeoff for 2 seconds
drone.hover(3) # hover for 3 seconds
drone.set_pitch(30) # set positive pitch at 30% power
drone.move(2) # forward for 2 seconds
#drone.set_roll(-30) # set negative roll at 30% power
#drone.move(1) # left for 2 seconds
#drone.set_pitch(-30) # set negative pitch at 30% power
#drone.move(1) # backward for 2 seconds
#drone.set_roll(30) # set positive roll at 30% power
#drone.move(2) # right for 2 seconds
Thanks in advance
