MTU is set to 527 #720

Hello,

i have found a strange Bug.

in Connect Callback i request a MTU Size of 247 with: conn->requestMtuExchange(247);

before Notify i get the MTU to fill my array with: Bluefruit.Connection(0)->getMtu();

With Android i get a Value of 247 -> as expected With Windows and Bleak i get a Value of 527!

How is that possible? I think that it is a Bug in Bleak, but how is it possible that Bluefruit is accepting a MTU Size of 527? All Limits should be at 247
