Problem contacting ESC

ejohnson01

I'm not 100% that this is your issue, but I think I have seen this when voxl-px4 is running in the background. Make sure to run systemctl stop voxl-px4 before running voxl-esc

I am facing a similar-natured issue after upgrading to SDK 1.1.2. While everything from voxl-esc tool works fine in my case (scan, spin). I am getting px4 warnings that arming is denied and failsafe triggered when I try to arm. Then when I run:

./voxl-esc-verify-params.py
./voxl-esc-scan.py
./voxl-esc-calibrate.py 

etc.

I get:

@Riccardo-Franceschini , can you please try to manually stop px4 before running any ESC scripts and let us know if the issue persists. If PX4 is running, it will interfere with proper operation of voxl-esc tools because they may be trying to use the same UART port.

systemctl stop voxl-px4

Hi, the voxl-px4 was not affecting the problem. It seems to be solved by performing a new factory reset, as explained here. However, we have now lost the calibration files. How can those be retrieved? We encountered a similar problem on two boards with serials M2100000J2R and M22000003EV.

@Riccardo-Franceschini , can you please clarify which calibration files you need?

Riccardo Franceschini

@Alex-Kushleyev sure are those :

Calibration File Status:
Missing /data/modalai/voxl-imu-server.cal 
Missing /data/modalai/opencv_tracking_intrinsics.yml 
Missing /data/modalai/opencv_stereo_front_intrinsics.yml 
Missing /data/modalai/opencv_stereo_front_extrinsics.yml 
Missing /data/modalai/opencv_stereo_rear_intrinsics.yml 
Missing /data/modalai/opencv_stereo_rear_extrinsics.yml 
Missing /data/px4/param/parameters_gyro.cal 
Missing /data/px4/param/parameters_acc.cal 
Missing /data/px4/param/parameters_level.cal 
Missing /data/px4/param/parameters_mag.ca

The camera ones and the IMU I can recover them by using the calibration tools but I haven't found a solution for the px4 ones

@Riccardo-Franceschini Can you just do the PX4 sensor calibrations to get new files? They only take a couple of minutes.

Riccardo Franceschini

@Eric-Katzfey
Hi Eric, I tried using QGroundControl. The accelerometer and gyro have been successfully calibrated, but I encountered an error stating "no mags" when attempting to calibrate the compass and then nothing happen. Do you have any ideas about what could be causing this issue?

Eric Katzfey

@Riccardo-Franceschini Can you provide some more details about your system? For example, what kind of magnetometer do you have?

Riccardo Franceschini

Hi @Eric-Katzfey eventually we managed to solve the problem by resetting to default the parameter of px4 and performing the calibration from qgc
