Loco positioning system is disfunctional

Post by 1016 » Tue Apr 17, 2018 3:28 pm

Hi, these days I have been trying to modify several example codes and it is successful!
But few days ago, loco positioning system was disfunctional suddenly. Drone's location was very irregular even though I used just original example code. For example, if i order the drone to move at (3,4,2), then it move very unnatural. I check it's location with pc client and it shows location like(0.5, 0.5, 1) or (2,3,20). Also, z coordinate increases continuously even though drone is still. I already understand loco positioning system and i am just going to make full use of them. But it deosn't work. I don't know what should i do..

Hi,

Without further info it is hard to know what could have gone wrong.
- Are you running the sytem in TWR or TDoA mode?
- What is the status of the LED on the loco deck: how many LEDs are blinking continiously?
- Is the position estimate in the client stable when the Crazyflie is in the anchor space or is it drifting away?

Ps. I moved the thread in the loco positioning system forum.
