ArduPlane 2.33 released

Posted by Andrew Tridgell on April 9, 2012 at 1:41am

We've just released ArduPlane 2.33 for your flying pleasure!

This release adds three new features over the previous release:

The new MAVLink stream handling means that when you ask for a telemetry stream you can now ask for any stream rate that is a multiple of 20ms period. Previously if you asked for 5 Hz for a stream then you got it at 3.3Hz, as we only supported 1, 3.3, 10 and 50 Hz streams. The new stream rate code is much more flexible.

The main motivation behind the new stream rate code is the ability to get the most out of the new 3DR radios. The new radios send information on their buffer state to APM, and the APM code can now adjust the telemetry stream rates to ensure that the internals buffer in the radio doesn't overflow. That allows you to run the serial link to the radio at a much higher baud rate than the radio link is using. So you can adjust the air data rate to improve range without having to reconfigure APM and the radio for a different serial rate.

The end result is that if you have a 3DR radio you no longer need to carefully adjust your MAVLink stream rates to fit in the radio bandwidth. Just ask for a high number and the APM will adjust the timing to whatever fits.

Happy flying!

    I have attached one of my yesterdays log.

     

    I had a few very short failsafe, because I went down to a valley, so there was lots of things between me and my plane. :)

    It was fun! :)

    Hi Andrew

    Newbie question. I see all the discussions for the APM and the new radios,

    At this time I am not comfortable with using the new radios on a UAS I may eventually sell as a product because of the uncertainty regarding certification.

    My current setup is using 900mhz Xbees and I am just putting it all together.

    My question is will the Various AMP2, Mission Planner and Arduplane softwares CONTINUE to support the Xbees? Or do I need to stick to a certain revision that will work correctly. How do I tell the softwares what to talk to?

     

    Thanks guys,

    Dwgsparky..... somewhere up the learning curve!

    Hello Andrew,

     

    I have found in the previous release that angle measurement over 60° is not correct.

    Is it fixed in this release?

     

    thx

    Hi to all!!  

    Gongrats to the Dev Team, the last month was like a torrent of releases and features, many thanks! Tridge tweaks things like minigun as far i can see, in GIT. Awesome Job!!

    For sure we are happy fliers, members, droners, clients etc. 

    but we will be excited- happy  Drone - Mappers if u plz implement camera tracking to the new code

    Many thanks again

    Regards 

    James
