Radio Quality Issue

[Lindbaergh]

Hi Max, yes it happens two times since sunday after i changed from 6.6.1 to r195. I spot checked the logs of the last 2 month, and as far as i can see i have small spikes where the signal is going down to 60 for less then a second in some rare cases. I do some althold PID tuning yesterday, so i fly not high and not far away from me. I make five flights and on two of them i found this 'drop', i append those logs so one can inspect them. Except the fw i changed nothing on my setup. i also inpected the hott logfiles, they dont show any drops or other stuff.

Anyone who can recreate this issue and compile their own FW, could you please try something?

Build the latest SVN version, but with -finline_functions removed from the build config. In CrossStudio, expand Project aqv6.6, expand Project Properties, dbl-click the first line "Additional C Compiler Only Options", and remove -finline_functions from the list. If using the Makefile instead of CS, remove that switch from CC_OPTS at line 148.

Then rebuild a release version, and see if you can recreate the radio quality problem.

Thanks,

Double click on the highlighted blue line in the Project Explorer sidebar, then delete the yellow highlighted option, and hit OK.

Hi Max

This does the trick. I made three flights this morning with r198 and the

#pragma GCC optimize ("-fno-inline")
static ....

and the radio quality stays @100%.
Thanks for the quick finding.

Cheers

Thanks Christof, that helped seal it. Also everyone else for your reports and testing!

Change has been pushed and I posted new fw builds at http://code.google.com/p/autoquad/downloads/list
