In this book measurement data and other information are transported mainly by serial wireless protocols as Wi-Fi or Bluetooth, to allow evaluations at the desired location and on a desired device. Using the microcontrollers ESP8266 and Digispark, the smartphone or tablet gets helpers to solve individual problems in the measurement technology. Freely available software is used, as a ready to use application or programming environments. The book is not trying to teach any programming language, but mainly uses and slightly modifies the supplied examples of the following chosen languages: rfo-Basic, ESPBasic, VB-Script, Java Script, HTML, C, C++.
