Hi is it possible to use a spare gps beacon ?

So basiclly I have a monster beacon but I had last event already 4 times that this becaon was not catched by the car. I'm using a ICD Pro and wanted to ask if it is possible that I give him a GPS posistion and a condition for example "no beacon in the last 200m" to make sure a becaon will be there.

I hope somebody can help me.

We are currently testing backup beacon features in our software, but it is not yet released.

However, with a bit of creativity it is possible to generate a beacon based on a math channel. 

The trick is to create an alarm that triggers when you want a beacon. You can then create a math channel that drives this alarm based on whatever conditions you want. Lap distance, GPS coordinates... etc. 

Bear in mind though that alarms as standard only run at 10Hz, which does not allow for very accurate timing. If your FreeCPU is high, you could run the Alarms node up to 100Hz to get more precision.

thx.

What is a high FreeCPU value. Atm I'm at ~33%.

33% is good, it effectively means you have 33% of the processor free, so you should have plenty of scope to add calculations to the setup.
If the mean freeCPU is below 9% then its best not to add much more.

That sounds good.
do you have a example of the math channel ?

something like

(choose([Distance] > 1500, 1, 0);

what we are saying here is that when lap distance is more than 1500 (or what ever the official lap distance is) this channel will return 1 else it will be 0. 

If then create an alarm based on this channel, you can select the event "Alarm Name Triggered" in the Circuit node for a beacon.

I would say add a few metres to the official lap distance, just to make sure you don't add a beacon when not needed. In most cases the IR beacon is not in the same location as the start/finish line, so the lap distance may be skewed.
