Intro … this past week I purchased the Craft/Sky telemetry module for the Taranis s.port at craftandtheoryllc.com/frsky- … r-pixhawk/
This requires that the Taranis be using firmware 2.1.x (I had 2.0.9 on it because I didn’t see a reason to update until then) AND that a modified 3.3.2 firmware be loaded. I understand from the owner of this design that he is currently working with the team to ensure that his modifications are included in the standard branches at some point.
This may be something not related to the firmware modification on the FC…it could be any number of things. I had to update the firmware on the Taranis from 2.0. to 2.1. I love the telemetry module sofar, but something has happened in between updating the firmwares that I no longer have real alt hold control on the Pixhawk as I used to. I set the THR_DZ on the PX firmware to 100 previous to this, and it gave me a manageable deadzone in the throttle deflection where I could maintain altitude. Since updating that has gone away.
Not sure if this is something on the Taranis, but it may be because I reverted my PX firmware for a bit back to what I was using AND to my saved parameter file and got the same issue. What I haven’t done is revert the Taranis back to the 2.0.x firmware.
I know this module probably hasn’t sold a lot of units just yet, but have any of you out there seen this? I cannot get any Pixhawk mode to keep a stable altitude at all right now when in modes that utilize it. I can tell by looking at the CTUN.Dalt parameter on a graph pre and post update that something is amiss. On the graph pre update, I see nice, stable flat lines where I’m in the throttle deadzone. The new graph doesn’t give me that.
Here is the graph pre update:
Now, here it is post update:
If needed I can provide a link to the last log which reflects the post update graph.
Thanks for your help.
