Hello drone doesn't work

Hi,

I’m trying to test the “Hello, drone” example from Air SDK, but it’s not working. I wonder if it’s necessary install a trusted certificate to testing the example

Hi

Could you be more specific what is “not working”. What is happening? Are you using airsdk-cli? Does the mission build fails or is it the installation ? Is there any error logs ?

If you’re using airsdk-cli with the default options, a default developer certificate is generated on your machine and installed on the drone before the mission itself.

The gimbal doesn’t make the greeting movement. There is not any errors. My installation is before the updating of the SDK with de airsdk-cli, installing the packages from the terminal.

Hi,

I’m facing almost similar problem. I’m following “Hello, Drone!” - 7.5 (installed airsdk-cli) example and I’m able to install mission to simulated drone.

But i don’t know how to properly activate it

I saw that it is possible to upload and activate airsdk missions through ‘Olympe’ (i would prefer this method), but from this example it’s not clear how to make it. Default code not working.

import logging

DRONE_IP = os.environ.get("DRONE_IP", "10.202.0.1")
HELLO_MISSION_URL = os.environ.get("HELLO_MISSION_URL", "com.parrot.missions.samples.hello.tar.gz")

olympe.log.update_config({"loggers": {"olympe": {"level": "INFO"}}})
logger = logging.getLogger("olympe")

Error:

I tried to make little changes only to activate mission, gimbal stared moving, but it went to infint loop (gimbal move every ~10 seconds), and getting errors, code:

Also I would like to add some movements to this mission like takeoff and fly simple squere or something like that. Should i change /airsdk-samples/hello/guidance/hello/hello.py file to achieve that? (Based on documentation citation " Guidance ")
