After almost a year adding features and fixing bugs, the LibrePilot team is very pleased to make 16.09 RC2 available to you. Some things still need to be fixed but it’s ready for widespread testing.

This is the second LibrePilot release, second release candidate.
A release candidate (RC) is a beta version with potential to be a final product, which is ready to release unless significant bugs emerge.

Since RC1 we've fixed the spurious "unsaved change will be lost" given when switching configuration tabs.  Some of the tabs would give you the warning even if you hadn't changed anything.  If you still get the warning when nothing was changed please let us know in this thread.

Another visible change is that the oplink tab is now always displayed even if an oplink isn't connected.

Known issues:

• [LP-289] - pidcontrol ne and down have nan dz if kp is zero
• [LP-303] - GCS menus broken when in full screen mode
• [LP-397] - ModelView misbehaving on MacOSX
• [LP-402] - GCS message - Invalid value for "Running"
• [LP-408] - No serial telemetry without OPLink
• [LP-421] - GCS setup wizard welcome panel is too big on high dpi screens

The full list of bug fixes and enhancements in this release is available at https://librepilot.atlassian.net/issues/?filter=10800

You need to “Upgrade&Erase” the board first - many UAVO have changed since release 15.09, and failure to follow this step will lead to problems!
Local templates (Tools->Export/Import Vehicle Template) can be used to backup important settings before you upgrade GCS and restore them after the upgrade.

Please report any issues first in this thread in this forum including detailed steps to reproduce the problem.
Make sure you keep safety at the forefront at all times: this is a release candidate that needs testing, not a final release.

New Hardware support:

• Sparky2 board
• Auxiliary Magnetometer: I2C and Naza GPS
• Revo FlexiIO port usage e.g. PPM+GPS

New input modes:

• Jeti Ex.Bus
• Graupner Hott
• FlySky IBus
• PPM up to 16 channels
• OpenLRS support for Revolution using internal radio module (no external receiver)

New telemetry protocols:

• MSP, MAVLink. OSD devices that use those protocols may now be connected directly (e.g.: minimosd with MWOSD).

New Flight oriented features:

• AlwaysStabilizeWhenArmed (Airmode) using switch
• Oneshot42/Multishot
• Measurement based D term gives smoother flight
• SuperExpo, you may need half expo value compared to rel15.09
• Camera tilt compensation
• Lower CPU load for CC3D
• Autotune is back

GCS improvements:

• PFD with terrain / OsgEarth improvements
• Failsafe settings using GUI
• Vehicle and Transmitter wizard improvements

Thank you hwh....

Thank you guys!
Just tested on X-210 with Sparky2, RS2205 motors with DAL 50x45x3 props (no GPS) racing quad. Autotune perfect.
Tested minimOSD (I am using Arris PDB with integrated minimOSD (https://www.amazon.com/gp/product/B01H6MG4OK/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) very convenient, and it has USB, so it is possible to reconfigure without disconnect.
minOPOSD works perfect, MWOSD does not work at all (with MAVLINK communication), latest development of minim-OSD-extra-887uni does not work. I tried both UAVTALK and MAVLINK.
Minim-OSD-Extra-R800 works fine (battery from FC, Horizon, RSSI), NO flight mode switch response, and panel switch set for ch8 but reacts on ch7 (in MinOPOSD channel switch is 8 and works fine).
I was looking for a bit more advanced horizon indication (center point, etc.) but all what works is the same.
Currently minimOPOSD is the simplest and works flawlessly.

16.09RC only support Sparky2, not Sparky1.
Sparky1 has a F3, not currently supported in code.

Hello, I want to try this release. Can I install it in my debian (jessie) distro? (.deb or src?)

Thank you in advance,
Don Carpincho.

Hi,

Packages are only supported starting with Debian stretch and above, Qt and osg packages are pretty old in Debian jessie.
Assuming you are not using a 32bits arch, if you want to compile by yourself you may need to install Qt locally in ./tools dir, compile osg/osgearth.
This allow run Gcs from sources dir and should work.

Will the LibrePilot2Go app be updated to include 16.09 RC2 UAVO as the last update included RC1 UAVO.

[f5soh]

I think the UAVO are the same

[@marc]

...slightly different. I just released a new version with Rc2 uavo.

[chromvis]

I just noticed that if I do not have Autotune active in one of my Flight Modes than I could not use SmoothQuick PID adjustment. Essentially when I do not have autotune in FM the whole SystemIndentState section is grayed out.
Sometime it is convenient to have SmoothQuick on.
I understand that it may not be simple to invoke one feature when the whole block is not activated, but may be for next release it is worth to consider.

[f5soh]

I don't know exactly what do you mean...

Why you want SmoothQuick if Autotune module is not used ?

[chromvis]

Actually, you are right, I used to vary responsiveness by changing SmoothQuick, but lately I was altering rate with just fixed PID.
So, there is indeed no need to have is active. Sorry.

Trying to upgrade and erase coming from rc1 and get timed out while waiting for a board to be fully connected...the same with librepilot clean configuration

Remove all power from the board and try the manual upgrade:
- Disconnect board from USB
- Hit Upgrade&Erase button
- Connect board to USB port
