VEML6070 after v1.1.0 not recognized anymore

[adrha]

The I2C-communication with the VEML6070 does not work with the HTCC-AB01-board later than the version v1.0.0. When running the I2C-scanner, the VEML6070 does not show up.

However, all other connected sensors like the SI7021 and BMP280 are recognized successfully and can be read out using the sample-scripts.

It appears to be an issue in Wire.cpp or something similar, which has an impact in the communication to the VEML6070 in a change between V1.0.0 and V1.1.0.

Following tests were made:

Board	SW-Version	Sensor	Result
HTCC-AB01	V1.0.0	VEML6070	Sensor shows up in I2C-scan and can be read out
HTCC-AB01	>=V1.1.0	VEML6070	No I2C-device found. Sample-script of VEML6070 reads 65535 (invalid)
HTCC-AB01	>=V1.1.0	SI7021	Sensor shows up in I2C-scan and can be read out
Arduino Uno	-	VEML6070	Sensor shows up in I2C-scan and can be read out
