Getting close first major milestone.

Today I got 5 prototype sensors to communicate with the main computer (iPad/iPhone) at once. I se now reason why we now should not be able to communicate with 36 units at the same time, only I did not make more than 5 units for now.
I also got the live graph plot to work, and found the memory leakage problem. It was the screen log buffer that got as large as the log file, and that had to fail sooner or later.
I got a small wind meter, a fan, and am close to do the test with a fictive sail. Just a couple of more days with preparation.
