Finally solved the problem.
Using the application of IOS, on the screen where the Mooshimeter appears, with the number of firmware and the level of the RF signal, and holding for more than 3 seconds, the software connects correctly with the meter, leaving the bootloader mode.
Now connect properly with my iPhone and my tablet with Android.
It would be very interesting to have a text document with history firmware versions (and software), explaining the changes in each version. Is a delay having to be investigating in the forum, to meet the new changes.
