Hey Taylor, happy to try and help!

On calibrating we try to keep the reprojection error as low as possible. You're getting an error of 1.42 which is almost triple what we'd like at worst. I'd recommend trying to recalibrate in different lighting conditions with as flat of a checkerboard as you can make. Even small imperfections here can lead to bad calibration.

Hope this helps!

@Taylor-Presley Please upgrade to the latest SDK, it should be resolved

@Cai-Bill Can you send a flight log of flying in manual mode and then trying to switch into position mode?

@Eric-Katzfey I've been stuck on travel for the past month but happy to report that your solution worked! input_rc is publishing and I was able to calibrate in QGC.

Hm thats super strange but I am glad you got it working! Keep us posted on how the project turns out 🙂

Thanks Eric!

VOXL comes in the VOXL-Flight configuration, which basically mates up an STM32 based flight controller (the Flight Core v1) with VOXL, then there's an internal UART connecting the two, and you can control the Flight Controller with 8-PWM outputs.

VOXL2 does support (currently in beta) the VOXL2 IO board which provides PWM outputs, and we've used it on a hex. See here for info on that use case. Again, this is in beta (not directly in the VOXL SDK at this point but in the dev channel).

Depending on your size constraints, VOXL2 also can be used like VOXL-Flight, where you can use an external flight controller (like Flight Core) externally, which has 8-ch PWM. See here for info on that use case.

(Why not native PWM? The VOXL/VOXL2 platforms are Snapdragon 820/865 based, which are primarily used in cell phones.... The PWM feature is not needed in cell phones, so these type of SoCs don't generally have native PWM...)
