APM Planner's ArduPilotSim issues

Posted by YureZzZ on April 22, 2011 at 5:05am

Hi there!

 

I'm having weird delays. I've checked CLI radio test and it's all fine there. So I'm guessing it is an issue of APM Planner software.

I've got delays from moving stick and showing it on the graph starts from 3 sec and keep increasing. I've seen even big as around 11 seconds. After 15 minutes (approx) ArduPilotSim stops respond on RC Transmitter commands at all, not even Mode switch. Also, when I try to close it - it stops responding.

Throttle stick works same way - with delays and also halfway offset. Lower half of the whole stick movement range is shown as zero in ArduPilotSim window, upper half starts from 0.000 and goes up to 1.000.
During all the test in APM Planner debug console window we could see a lots of strings like 'bps 2291 loss 2', where first number changes and second stays the same.

Here is what occasionally appears in ArduPilotSim log window

Opened com port

NO SIM data - 20

Please check your radio setup - CLI -> setup -> radio!!!

I've erased EEPROM completely, then factory reset, then setup everything and run every test. Everything looks fine. I even trimmed my RC transmitter, so that in CLI radio test in neutral postions it shows 0 for all used channels except ch8.

 

Nope, I'm not having my GPS device connected to APM board - I'm using x-plane sim only for now. 

 

I hope it helps to fix that issue.

    are you trying xplanes of flightgear? i think there might be an issue with flightgear, but xplanes should be fine.

    I share your frustration.

    After struggling to get FlightGear going with the .bat file (no instructions for 64-bit OSs) I also get "NO SIM data - 20" errors when trying to link to the ArduPilotSim. I wrote a UDP listener app that listens to the outputs of the GPS data from FlightGear to the local host ip of 127.0.0.1 and I can see data coming in from the FlightGear Sim, but the ArduPilotSim is not finding these packets.

    Can anyone help? Is there something else that needs to be set up?

     

    Thanks

    Jaques
