Redis race condition...

[luigisaetta]

I think there is the risk that the infromation on the position, coming from GPS app running on phone, arrives after the GET from the Python app (canncormain). This way the position is not yet defined. It should get (0,0)... but we need to check.

But at the same time the Phone app wants to talk with Raspberry, to send position. Perfect match to create a race condition.
Need to check, to avoid difficult to diagnose starting errors.
Maybe add a sleep to the start of Python app. Good for demo.
