Rework pressure/ temperature data aquisition The data data provided by the I2C data had been used for calculation independend if transmission was successfull or not => state evaluation added In the previous version data with resolution 0.5mBar and temperature was requested per cycle inparallel. This has been replaced by a requested resolution of 1mBar and an alternating aquisition (pressure / temp update every 200ms instead every 100ms) => reducing busy wait time and power consumption
