To work with ESP32 Library change this part, on file .ccp line 58

uint8_t VEML7700:: receiveData(uint8_t command, uint16_t& data) { Wire.beginTransmission(I2C_ADDRESS); if (Wire.write(command) != 1){ return STATUS_ERROR; } if (Wire.endTransmission(false) != 7 ){ // NB: don't send stop here return STATUS_ERROR; } if (Wire.requestFrom(uint8_t(I2C_ADDRESS), uint8_t(2)) != 2){ return STATUS_ERROR; } data = Wire.read(); data |= uint16_t(Wire.read()) << 8; return STATUS_OK; }

This needs to conditionally compiled in, since it's an issue specific to ESP32 I2C. Having just the "!=7" breaks it on the other boards. I'll consider changing it to work around the broken ESP32 hardware, but I don't have the cycles to do it immediately.
