Obstacle avoidance, Mini 3 Pro, Dronelink 4.6.0 Beta
Hello, I have question, in older version it was not possible to run mission with obstacle avoidance enabled. I noticed in 4.6.0 it is possible. It means that obstacle avoidance is working now? I had enabled bypass mode in firmware. But it seems to be not working with Dronelink well, I can go near the drone from forwards or backwards and nothing happened (drone stay on the place). But when I tested Follow mode and navigate the drone near to the ground, Follow mode interrupted. It means something works. How should it be works in this phase of Beta?
Thank you.

Can you provide more details or a screen recording showing the behavior? To our knowledge obstacle avoidance doesn't work in any case during virtual stick, regardless of APAS.
As far as the bottom sensors, the Mini 3 pro is same as most DJI drones with or even without obstacle avoidance. There are at least two different types and one of them is basically a ground sensor whether it’s infrared or other type. Even a drone without obstacle avoidance has them and they will slow the drone down and keep if from smashing into the ground fast. I believe since you stated you were near the ground that’s what happened. As Jim said, the obstacle avoidance doesn’t work with the Mini 3 at this point so sounds like it was just the bottom sensor.
Hello, it is interesting but just now at evening I tried Dronelink with Mini 3 Pro in manual mode in garden. Drone bypassed me when I navigate it direct to me, the same with trees. When I navigated it into the wall stayed hover. I tested little missions "on the fly" with near waypoints near trees and it seems as obstacle avoidance works in some cases but I am not sure. Tomorrow I will test this in slow speed with waypoints and in follow mode. Rather with propeller guards.
Jim: ok I will try screen record
I tested today two waypoints low above the ground.
1) When I stepped into the path of the drone it stopped immediatelly. Not bypassed me and time of mission runned out, while I was standing before the drone.
2) Next use case: when I stepped out from the path, drone was continued, but minus the time it was stopped and drone stopped before the last waypoint. Drone not finished mission exactly to the last waypoint.
I must say, It is better than crashed into obstacle, but it should bypassed obstacle.
So your current testing / experience is that obstacle avoidance is currently working?
We can confirm that obstacle avoidance does appear to be working for the Mini 3 pro during virtual stick.
Yes it works but on mission drone only stops. On manual fly is object bypassed.
Right, to be clear this is just the same behavior as MSDKv4 (doesn't run into things).
Here's how it went today and how obstacle avoidance worked out. Launched from roof as always with a mission from same spot that was used hundreds of times. It has about 2.4m of clearance from roof to the edge of roof above to take off, stop when edge is detected by top-rear facing sensors. This time it just took off and continued to ascend, clipped the edge of the roof, went upside down and started trimming shingles. Everything stopped only when one of the motors detected resistence. Brand new just replaced blades... Tried DJI fly app and it went without any issues, so sensors worked fine, but for some reason were not picked up on this mission.
And that is why you don't actually start a mission till the drone is in clear airspace....
Had you clearly got a home point set
Martin Reading, I can not disagree, but since process was tested so many times I forgot technology makes mistakes too. Just happy this time it's just blades.
Hopefully you have it properly insured, just in case something worse than blades happens
Ouch…..l never trust them in really close proximity as they are OA safety sensors, not bullet proof. I do suggest recalibrating the IMU and Compass especially with how much prop damage there is. I’m sure you have already thought of this but a small reminder. Luckily props are cheap and hopefully there isn’t any unseen damage. I would test in an open area a few times to make sure it is operating correctly.
Thanks guys. Yeah during two years that I had it I've had a fair share of mishaps. Some minor like this, some bigger when it almost ran away. Bought it mostly for partly automated flights, but apparently mini 3 pro is way too far away from being reliable at this.
