I have also buy it from Elektor, but in France.

And I have always many problems to connect it with android in my office.

The apk find the mooshimeter, but I CANT connect it.

For me, it is because wifi. I have to go outdoor to connect it, then I go back to my office. And all work fine.

BLE seems to be powerless.

And yes, I tried others wifi channels ;=)
