Hey,

From the logs I see that you've sent only 2 commands - First one is flat trim and other is take off. And the flying state is still set to taking off which tells me that the drone is still taking off. It has not completed the take off.

That's why even if you send the command to land the drone, its not gonna work. You need to wait until the drone completes its take off and sends you the flying state as hovering.

I am issuing your standard program ... it does not land ever

[markusvankempen]

here the program var minidrone = require('../index'); minidrone.enableLogging(); var navDataStream = minidrone.getNavDataStream(); navDataStream.subscribe((data) => { console.log(data); }, err => debug(err), () => debug('complete'));

minidrone.connect('Mars_') .then(() => minidrone.flatTrim()) .then(() => minidrone.takeOff()) .then(() => minidrone.flatTrim()) .then(() => minidrone.forward(5, 5)) .then(() => minidrone.flatTrim()) .then(() => minidrone.land()) .then() .catch((e) => { console.log('Error occurred: ' + e); });
