V2.3 Baro Issue

[QuadBow]

Hi developers,

I've just found out that version 2.3 has been released and have tested it.
Surprisingly, the copter didn't arm at all. After some research in this forum I found out:
It's not a bug, it's a feature! http://www.multiwii.com/forum/viewtopic.php?f=8&t=4246

Unfortunately, this feature doesn't suit me fine, since I use always BARO and I don't have any channel free.

I understand the rationale for the need of a change due to http://www.multiwii.com/forum/viewtopic.php?f=8&t=3910, but:
Why hasn't this been an issue in V2.2?
Isn't there a better solution than forcing to switch off the baro?
Isn't the baro's calibration to new ground level when arming the better solution?

Hi,

I think the problem mentioned was in 2.2.
But in 2.3, only the vario mode was kept.
If you want to keep the possibility to have a permanent baro mode (but still in vario mode),
maybe you can hard disable it in code if throttle is in the range [1000;MICHECK+small margin].
would it be ok like this ?

Hi Alexinparis,
Thank you very much for your proposal.
Even if the altitude hold implementation has not shown the best results it appears to me now, that the vario mode is not usable for me at all.
If I switch it on, the copter is loosing height significantly.
Thus, I decided not to use the baro function and to wait for something better in the future.
Or can I configure the baro behaviour?
Thanks a lot in advance.
Best
