Sadly, as much as I would be for allowing anything that simplifies peer to peer communication between robots and teams, it cannot be based on WiFi as @amy.eguchi has mentioned in this thread. Similarly to what @stormingrobots said in that thread, I personally also do not like the status quo and will try my best to see if it can be changed somehow. But for now it seem we will have to manage without WiFi.
That being said, we are trying to work on something that would both allow communication between various robots and at the same time adhere to the current rules (i.e. would not require WiFi).
Stay tuned for more updates and thanks a ton for all your activity on the forum!
