After performing a short test on different pings, I've got pretty promising results!
Here's a graph depicting the Round-Trip ping time, measured by sending a Timestamp to the MQTT Network and recording its arrival time. The ESP was connected over my mobile-phone ((which had its mobile hotspot open), which connected via the internet to my local MQTT server.
As you can see, most pings are in the 250ms region, with only a few of them exceeding a second. This isn't perfect, but sufficient for most cases, as the lasertag-weapons will be capable of running fairly stand-alone.
A direct WiFi connect was, understandably, hard to beat. I got a constant ~20ms Round-Trip time for the ping. HOWEVER, at the same time the signal reach is very limited and would require us to set up a fairly large outdoor WiFi net to achieve similar coverage.
My vote is to use our phone's mobile hotspots. It's a bit slower but covers any area with normal broadband internet access.
Since the ESP will be acting as a bridge between these different software levels, it is now important to come up with a fitting and "smooth" concept to handle data.
We could either:
Personally, I would go for the last option. It would give us the most processing power for that stuff (with floats, 32-bit processing power and more RAM), and since the communication between AVR and ESP will be so close and error-free, it would be easy to have the ESP "master" the AVR.
We also have to think about how to implement things like special effects, how damage is received, and especially: Shot Arbitration
I know it's a lot, but it would be nice to come up with a simple and hackable system that allows for easy expansion of everything :3
