Test from the phone: the thermometer widget shows the unit of degrees kelvin. Conversion OK. The barometer widget displays values in pascals. Can not change drive.
From the navigator: the thermometer allows to make all the changes. Meanwhile, with the barometer the problem continues. It stops displaying values if you try to change to hectopascals.
It is necessary to reinstall the sensor to see the pressure again.
With Arduino Mega + Shield Ethernet W5100 the same thing happens.
