PLND_BUS = 0
PLND_ENABLED = 1
PLND_TYPE = 2
PLND_EST_TYPE = 0

I am also trying the same but didn’t get the results. Tried testing EST_TYPE = 0 as well as 1, but it didn’t work.

I have few queries mentioned below.

  1. Can i use rangefinder like Tera One.
  2. How to identify Prec Loiter is executed or not.
  3. Is Prec Landing and Loiter works in non GPS environment.
  4. Minimum height require to test the system.
  5. In which modes the prec land works like (guided, loiter, alt hold etc)

Thanks for your precious time.

@AmitSingh

Your log shows flight altitudes of only ~1 meter (rangefinder altitude). You will need to do Precision Landing test flights at ~10-15 meters.

Ok. I will test that and will come back with results.
Also, i have few doubts as mentioned above also. @ThomasSFL please address that also. That would be very helpful for executing different stuffs with IRLock.

Yes, GPS is required for the Precision Landing feature.

You can use a different rangefinder. However, the LW20 is the most robust against IR interference.

Hello all!

I’m working on implementing IRLock into my current drone and have ran into an issue. I have a Maxbotix I2C Sonar Rangefinder hooked up the my flight controller (Cube Black) with the IRLock Camera Sensor reading from a MarkOne Beacon. I am using a I2C splitter so that both the Camera and Rangefinder can interface with the FC. I am getting values from the rangefinder without issue, but am not seeing anything from the camera. If I arm, put into land mode, and examine logs, the health and target acquired are both zero. I haven’t messed with the settings on the PixyCam at all.

If anyone has suggestions, I’m all ears!

PixyCam version: 1.0.3

Arducopter 4.0.3

FC: Cube Black

Hello @coleravi and @markb2309
I am facing the same issue, all works but the camera doesn’t recognize the beacon. Did you change something in the configuration? some threshold or brightness? I am guessing there Is the solution but I couldn’t find more information about it.
Thanks!
