readHeight

Read current height of Parrot drone

Since R2019a

Syntax

[height,time] = readHeight(parrotObj)

Description

[height,time] = readHeight(parrotObj) returns the current height above the takeoff surface in meters along with the time stamp of the Parrot^® drone, specified as a parrot object. The function returns the height only after the drone has taken off. For a Parrot Mambo drone, before takeoff, the function returns a zero.
