No need to wait after Wire.requestFrom() and it should not be followed by Wire.endTransmission().

In the files:

• waspmoteapi/libraries/SensorGas_PRO/MCP3421.cpp
• waspmoteapi/libraries/UltrasoundSensor/UltrasoundSensor.cpp
• waspmoteapi/waspmote-api/WaspEEPROM.cpp
• waspmoteapi/waspmote-api/WaspRTC.cpp

there is waiting with timeout and sometimes a Wire.endTransmission() after a Wire.requestFrom(). All of that is not needed.

I assume that the changed Wire library still works just like the official Arduino Wire library.

Explanation: Common-mistakes, number 1 and 2.

Hi Koepel,

Thanks for your contribution. We will take a look into the API to correct it.
