finishing up after 1 1/2 days, that must be a record!
Kakute F7 HDV which I am converting to ELRS to evaluate a receiver.
I believe I had 2 main problems: 1) it appears the official releases, at least for this AP, maybe others, do NOT support ELRS /CRSF(passthru telemetry, that is…I had no trouble getting radio channels to come in), in spite of the instructions in Ardupilot doc and elsewhere. I downloaded a custom build, herein I believe, and it got the arducopter telemetry to show up on the telemetry setup screen (radio; you may have to use Discover new). Then found (with hints herein) that the Dev versions which can be manually downloaded and installed, support ELRS/CRSF. Well, I can kind of guess why that is, but where is the doc?
Oh, I also used a multimeter scope, and could see the telemetry coming out on serial 3 Tx once I loaded a non-release version.
2) once I had telemetry in the radio, I finally re-installed the Yappu widget under transmitter screen setup (after going over, and over things for hours), and when asked to select a version (after selecting Yappu), I selected the default instead of what resolution I thought my TX16s is… I saw that mentioned herein, but did not get where to do that default thing. (My screen worked, but the diagnostic said NO TELEMETRY, when there are gobs of telemetry. The problem appears to have been a screen configuration selection problem of some sort.)
Now working well. And only a day and 1/2 of my life.
Let’s see: RC_Options: 8992; RC_Protocols: 512; Serial3_Options: 0; Serial3_Protocol: 23 (29 - Crossfire doesnt work!) ; Serial3_Baud : 115 (I believe this totally doesnt matter) (all in Mission Planner)
So, there you have it, simple enough! I may have forgotten something, but no matter, you will figure it out in a week or so… (I did enable CRSF in the Yappu Config which shows up under System tools. I wound up with an old Yappu menu still, under scripts, which I suspect is a remnant of the copy/paste and does nothing now. I may clean that up later.)
