Hi
Yesterday i upgrade to V2 software and after that i start having big wind gust spikes (over 130km/h) i never had that before the upgrade.
I have a Davis anemometer connected to the tx board.
I revert the tx unit back to 1.5 but still have wind gust spikes, after i revert the RX board to 1.5 no more spikes!

An idea of the cause of my problem ?

Thanks

Hi

Please try to enable the Wind Spike Control in RX user configurable settings, it may solve the spike issues.
Just for curiosity, there were thunderstorms today in your region?

Code:

// --------------------------------------------------------------------------------------
//   Define use of Wind Gust Spike prevention routines
// --------------------------------------------------------------------------------------
#define WindSpikeControl 1   // 0= Disable, 1= Enable

Hi

I thought about that solution, but why is it working in V1.5 without this spike control ?

No just a little wind with average of 12-13km/h

I looked at the code and i saw that there was a spike control in V1.5.
Is the one in V2 as effective?
I ask that because the two spike removal are really different.
Thanks

Yes, they are really different. In v1.5 a reading that could be considered as a possible spike is completely discarded, in v2.0 a possible spike (if greater than 50 km/h) is limited to last gust value, times three. The spike is not completely eliminated, but strongly reduced.
Both methods have pros an cons. As spikes generally have a high value, I believe the method used in v2.00 is also effective, but I can be wrong or had missed any detail. If you have any reason to believe the method used in v2.0 can cause troubles, please tell me.
Have you already tried to activated it?

My question about the thunderstorms, is because the only occasion where I get spikes from my anemometer readings is during very close thunderstorms. Every time there is a strike I get a high spike on the gust readings, otherwise I never get any spike.

I think i can try V2.0 with spike control enabled tomorow.
I'll let you know if it's ok.

Ok, feedback is always appreciated.

Hi,
V2.0 spike control give me significative higher gust than V1.5.
WD 1.5 graph
   

WD 2.0 graph
   

Indeed it's the same period, I managed to build a second RX on a breadboard connected to CMX.

For the moment i'm using V2 software with V1.5 wind spike control.

V2.0 spike control give me significative higher gust than V1.5.

Are you sure? The v1.5 graph shows gusts up around 50 km/h, whereas the v2.0 graph shows maximum values around 35 km/h.

[laulau]

Oups! I have inversed the graph names.
I'm sure here is the historic for the same period and i had V1.5 RX soft running.
V max ~35km/h so the V2 graph is the one with 50km/h gusts.
   
I can repeat the comparison at some point if needed.
