Number of Waypoints

First i say hello because I am a new member. (sorry for my English. I am Spanish speaking)
Hi, I have a x8 wing with px4 autopilot.
I use that with Mision Planner, and when i try to charge a flight plan with 170 waypoint or more, my system does not work.
specifically, if interrogated px4 having sent over 170 waypoint, do not return anything.
How waipoints has at most?
It is a problem of firmware or software?
Thanks

  • Hi Michael

    I did the update yesterday evening. But it still don't work. I can save a WP File with over 254 waypoints to my computer but I can't load it again with the "Load WP File" button. The message "too many waypoints" appears... 

    Thanks a lot

  • Hi Michael,

    please update MP, there was a limit of 255 wp's but is now fixed. latest mp is 1.3.21

    Hi Martin,

    Currently it is limited to 127. I plan on increasing this a lot on PX4 soon, but haven't done it yet.

    Cheers, Tridge

    • Anything changed here? I still can't seem to write more than about 150 waypoints...  I'm using the Pixhawk -- plenty of memory, right?

      • Developer

        The limit is now a bit over 700 (in fact 724 for plane/rover and 718 for copter)

        That will only apply to copter once 3.2 is out though. You could try a beta version if you need more now.

        Cheers, Tridge

        • Thanks, Tridge. That's great news. I understand that was added in 3.1 plane, right? I'll upgrade if so.

          If it's not too hard to explain, why the 'odd' limits?  Will the number eventually grow significantly greater for big mapping missions, or have we reached some memory barrier?

            It's the number of bytes available in the 16k FRAM of the Pixhawk for missions. See this code:

            https://github.com/diydrones/ardupilot/blob/master/libraries/Storag...

            we may support having mission items on the microSD card in future, in which case you would be able to go much larger, but for now that is all we can do.

            Cheers, Tridge
