brother, drone kit work with python 2.7 but other version mode set not work! and i am try and tired! i can't install dronekit 2.9.0 in python 3 or 4 also in windows mavproxy can't change mode return the same mode!

[@PankajMali]

Hi, Use python version 3.6. And if you already have anyother pythin 3 eg. Pythin 3.8/3.11 then set python 3.6 on default and then install all the pythin packages using pip3 install . It will workk

I take error WARNING:dronekit:Link timeout, no heartbeat in last 5 seconds, what should I do?

[@PankajMali]

The only reasons for this error are 1. Check the rx tx pins if rhey got interchanged 2. Check for the Bluetooth disable step

[@tturkmen]

Helle. Good work. I write some dronekit, connect pixhawk from laptop using by telemetry but it does take off. What ı must do from transmitter? Can you help me?

[@PankajMali]

Hello, Transmitter is just for safety/ like a backup controller ...only thing you need to when you want to use transmitter before changing mode from transmitter just keep your throttle stick to mid positio and then change mode to take manual control .

[@ais_robotic]

can u communicate between apm/pixhwak and arduino???

[@PankajMali]

Yes it works

[@santiagoperez6769]

Very cool drone brother! I tried following along, but I am getting unusual behavior when hovering and was wondering if you could help me. I used your code to takeoff, but once I get the "altitude reached" message, the drone does not stay still at the desired altitude. Instead, it oscillates up and down, like its in water, and never hovers in place, like yours does, until the mode is switched to LAND mode. So if I try to hover at 2 meters, it will get to 2 * 0.95, then it will bob up to 3, then down to 1, then back up to 3, then back down to 1, and neither of those is 2 * 0.95. I have the break statement when altitude is reached, so I am not sure what is happeneing. I also did several autotune. Have you ever experienced this?

[@PankajMali]

Hello, In order to debug this issue, i request you to take off using RC and put the drone in Loiter mode and just observe . If you find similar behaviour then its because of the faculty measurement. I have this same issue 7 years back with chinese cloned pixhawk 2.4.8, i replace the autopilot and it was all good. When ever i was gaining or loosing altutude it used to do up and down with some jerks.

[@santiagoperez6769]

@@PankajMali Oh really, interesting... I also have the 2.4.8 chinese clone. However, I think my issue might be different because I just tried a flight and put it in loiter to reproduce the bug, like you said, but it did not reproduce the bug. When I enabled loiter from my RC controller, it hovered very still, with no dipping up and down. Its a very strange bug, and now I am thinking that it might have something to do with the dronekit code and my copter version. I am running Copter version 4.3.7, so I am wondering if something behind the scenes has changed from the older versions. Do you remember what Copter version you were using in the mission from the video? If thats the case, then I might have to code up a PID controller or something because the dipping up and down oscillations are very symmetric. If I set the desired height to 2, then it oscillates between 1 and 3. After checking the dataflash log, I see a dampinging happening aswell so that the wave goes 3 to 1, then 2.7 to 1.3, then 2.5 to 1.5, and stays there such that the drone keeps dipping up and down. I will also try to go up higher, like 15 meters, and try to hover for a longer duration, like you do. Wish me luck as I try to take a deep dive into debugging territory lol.

[@santhoshmamidisetti]

can you please tell the delay thing, I mean the first method at 6:28 . and also what switch has to be toggled ? to take manual control , I mean what actually is that switch ??

[@PankajMali]

Hello, In this video i have executed the code from laptop using ssh . Anothet way is to add your python code to the shell script so that it will start the code as soon as drone is powered and gor safety purpose you can add some 1 min delay so that you can stand away from drone once powered on. You will be having a flight mode switch on your transmitter which has user defined modes like stabilize, loiter , rtl, alt hold etc ...so whenever you execute your code and want to take manul then just an interrupt has to be generated from your transmitter, so its like you just toggle your mode switch irrespective of its initial position...just toggle it and take manual control and dont forget to keep throttle at 50 percent. Good luck

Sir, I want to do only flight planning.. i.e. making waypoints using python then it will export a KML. I will put that waypoint KML in a software and drone will fly. How to do flight plan using python, where I will input area KML, wind direction, overlap and it will make waypoint

[@PankajMali]

Hello ankit , In order to create waypoint from a kml . You need to use pykml package 1) from pykml import parser 2) root =parser.fromstring(open('BatchGeo.kml', 'r').read()) 3) print root.Document.Placemark.Point.coordinates So basically above steps will read a kml file and print the coordinates. As per your requirements you can fetch the coordinates one by one to a python array and then access them as waypoints .

when you send the script the remote in witch mode should be because i put it in the stabilize mode after thet i send the code after few sec the drone armed but dont go up stay on the ground so what i should choose the mode frome remote wile fliying it from the script an help please???????????????

[@PankajMali]

Good question Mohamed When you run a python script you can keep your transmitter in any mode like stabilize or loiter it doesnt matter. I mainly have it in stabilize mode so that when ever i want to get manual control i flip the switch to loiter and the copter is steady. Main thing to remember is you dont change the mode from transmitter once you run the script as it will generate a interrupt and tell the system to get manual access and it wont takeoff. Once it takes off just keep the throttle to 50 percent in case required to take manual control, before takeoff dont move any switch on transmitter.

Would this work for a drone that fly in indoor places (non-gps places)

Yes this script can be tested with no gps guided mode but not recommended unless and until your are specific about the sensors or the approach that you take to build your system like ..... you can use px4 flow sensor as an alternate to gps for position hold and you can use vision based navigation stack like any cameras along with visual markers or can go with lidar based approach .

Great Video! I have successfully done this command: Python mavproxy.py --master=/dev/ttyAMA0 --baudrate 921600 --aircraft MyCopter But when I try to run the python demo.py script, I do not get a connection. I set the correct/same baudrate in Missionplanner for Serial 2. Any ideas what I could have missed? I get the message "waiting for heartbeat from /dev/ttyAMA0 Thanks a lot for the great videos!

Gald it helped you, Run the script with this command Python demo.py - -connect /dev/ttyAMA0

@@PankajMali i did it exactly with this command. I use a raspberry Pi4. If the mavproxy.py script works fine, all baudrate settings have to be correct, right?

[@PankajMali]

Yes you are correct

[@cherryFPV]

@@PankajMali Unfortunately it still does not work. pi@raspberrypi:~ $ python vehicle_state.py --connect /dev/ttyAMA0 Connecting to vehicle on: /dev/ttyAMA0 WARNING:dronekit:Link timeout, no heartbeat in last 5 seconds Any ideas?

[@PankajMali]

This error occurs due to 1. Tx rx pins incorrectly connected ( but in your case pi connects successfully with pixhawk) 2. Port no is not correct, i will tell you a port you try connecting on that port , both running mavproxy.py and also to run the python script. For pi4 it doesnt work for ttyama0 go for serial0 or ttys0
