RPI, Common/Ubuntu: small fixes for RPI4 image for use with T265 #51

Closed rmackay9 closed 4 years ago

rmackay9 commented 4 years ago

This PR makes some small fixes to the RPI2/Ubuntu and Common/Ubuntu scripts to ensure the APSync image works with the Intel RealSense T265 cameras:

on startup uhubctl (which powers off/on the USB ports) runs before the t265_to_mavlink scripts run. We accomplish by changing the installation order so the entries in etc/local.rc are swappedc
remove the (unused) copy of Thien's t265_to_mavlink.py script
add some scripts to allow users to more easily start and stop the wifi access point
wifi access point works on 5Ghz only. 2.5Ghz interferes with USB3 which is what the T265 uses

I'm pushing this to master immediately so that I can make speedy progress on getting another APSync image out. Still, I'll monitor this thread and all comments welcome.

i'm a bit dubious about turning off the 2.4ghz for everyone, all the time, as 2.4 is a much more widely used frequency , particularly in low cost gear , and has higher range as well. is there a way to maybe only disable it when using t265 related tools?

rmackay9 commented 4 years ago

@davidbuzz, yes, it's a good point. For now I'm only making RPI4 images for use with the T265. I wonder if these scripts are in good enough shape that anyone besides Peter, Jaime or I actually use them... so perhaps I will have advanced warning before someone hits this issue.
