Hello Modal AI team,

The error I get went flashing a new SDK

error: insufficient permissions for device: user in plugdev group; are your udev rules wrong?
See [http://developer.android.com/tools/device.html] for more information

When I run adb devices:

List of devices attached
a0d316ec no permissions (user in plugdev group; are your udev rules wrong?); see [http://developer.android.com/tools/device.html]

Do you know what I should do?

@Alex-Kushleyev Hi Alex, would these commands work with the M0134 Variant as well?

@Eric-Katzfey when using the voxl-send-esc-pwm-cmd do you know how I would be able to trigger the VREF Pin on the ESC 4-in-1?

I have tried running:

sudo voxl-send-esc-pwm-cmd -p 12 -w 2201
sudo voxl-send-esc-pwm-cmd -p 11 -w 2000

and when I measure the voltage from that wire I get ~0.01V which I presume to be noise.

Is there something that I am missing?

I am looking to produce a 5V Rail.

I am trying to run voxl-vision-hub and that requires voxl-qvio-server to be running. However, when I start it, it says one of its internal libraries (libvoxl_common_config.so) cannot be run since it is a 64-bit library. Then, I realized that the voxl-qvio-server package I have is 32-bit while all the other packages are 64-bit. I tried to reinstall voxl-qvio-server from the newest VOXL2 SDK Platform release, but that one is still 32-bit even though the DEB file is labeled arm64. Does anyone know how to solve this issue?

@Eric-Katzfey I figured out that I did not need it for my project, Thank you thought!

@Eric-Katzfey Thank you I got this helped a lot! I was able to get it working with root access!

Did you try running voxl-configure-rangefinders?

Yes I have, and these are the outputs:

voxl2:/$ voxl-configure-rangefinders
missing required argument

Start wizard with prompts:
voxl-configure-rangefinders

Shortcut configuration arguments for scripted setup.
factory_enable will reset the config file to factory defaults
before enabling the service.

voxl-configure-rangefinders disable
voxl-configure-rangefinders 1_on_m0141
voxl-configure-rangefinders 1_downward_on_m0141
voxl-configure-rangefinders 4_on_m0141
voxl-configure-rangefinders 1_downward_on_m0173
voxl-configure-rangefinders enable

1_downward_on_m0141 is for a downward sensor, this enables mavlink
broadcast to the autopilot as a landing sensor

show this help message:
voxl-configure-rangefinders help

is there a certain option I should select?

Hello Modal AI team,

I am trying to enable and run voxl-io-server. I was successfully able to enable it but when starting the system, it would not run. I ran into this error when I asked for its status

@Eric-Katzfey How can I control those PWM signals? Since at the moment I am not reading anything from any of the pins.

@Eric-Katzfey Correct me if I am wrong, but doesn't the ESC only have enough motor outputs for each of the propellers? So to add another PWM signal I need to either use a GPIO pin or the expansion voxl2 IO board
