I posted this over on ArduPilot.org, hoping you guys can provide some insight as well.
I've been toying around with this in my spare time and want to wrap it up before the weather gets harsh here. I'm stuck on what I think is my final problem. I've got a 3DR Iris+ that has TELEM2 from the Pixhawk connected to an FPV/LTE device.
When I launch the FPV client and connect to it via Mission Planner, I am able to connect over LTE and can retrieve/view the Pixhawk in Mission Planner. If I move the drone, I see the movements happen on-screen.
The problem is for some reason I cannot write WPs (or even read WPs) to the device. Actually, scratch that. It seems to partially work (tested it as I was writing this up)! On some occasions, when I select Write WPs, it times out right away with:
In some other instances, I actually saw it write a couple of WPs and then fail at maybe the 3rd or 4th one. I also successfully Read WPs one time. So, it sounds like the connection/cabling is good in-fact, and maybe it's a parameters issue?
Here's how they are connected anyways:
Would appreciate any help/feedback you can provide. Thanks!
