RC Missing parameters on Sentinel

martygp95 · 26 Jul 2023, 10:10

Hi, I just updated one Sentinel to the latest image available (VOXL2 SDK 1.0.0, released in July 12). The flashing was succesful and the Sentinel was assigned with a proper SKU number (MRB-D0006-4-V1-C4).
I tried after to bind the RC (Spektrum Dx6e) using the command qrb5165-bind -s inside the drone terminal; the binding was successful (receiver light goes in constant orange). But when I try to assign the channels to the switches in QGrounControl, this pop-up appears (sometimes with more parameters):

I can see the raw data from mavlink changing values as I move the toggles in the RC, but it seems that even though I assing for example, the Kill Switch into one of the proper channels, the QGroundControl does not notify that the KillSwitch is Engaged or Disengaged. For the previous voxl-version, the platform 0.9.5, I was able to bind the RC and none of this pop-ups where happening. Would appreciate any feedback! Thanks

Hi again, could it be that QGroundControl still does not support this new version? otherwise I cannot perform a manual flight as I cannot configure the RC parameters

@martygp95 What version of QGC are you using? You shouldn't be seeing those messages. What communication method are you using for QGC? Perhaps it is having trouble sending the parameter list over the link on QGC startup?

@Eric-Katzfey Could be, I am using this config to connect to the Sentinel (IP is 192.168.1.75)

Also, the QGroundControl version is 4.2.8:

I normally used the qgc_ip param to directly connect the drone to QGC in voxl-vision-px4.conf,when the service was there but now with the new version I do not know if that param is still available somewhere.

@martygp95 Your QGC version should be fine. When you start QGC do you see a little green bar at the top of the screen slowly moving from left to right? And then get a warning about not all parameters were received?

martygp95 · 27 Jul 2023, 16:21

@Eric-Katzfey yes I see the Green bar and then It appears the pop-up

@martygp95 This may indicate a very slow or weak wireless link. Are you using WiFi? Perhaps you have a lot of interference?

Eric Katzfey · 27 Jul 2023, 16:30

@Eric-Katzfey QGC asks PX4 for a full list of it's parameters on startup. It's a lot of parameters to transfer (over 600!) so if the wireless link isn't strong enough it may time out and not get all of the parameters.

@Eric-Katzfey okey, tomorrow I will try to set up a local network with a router and I will let you know!
