I can change the register 0x35 with the data I need but the eeprom is always in the default value after a soft reset. Anyone has any idea please?
Thank you very much!</p>

Since the least-significant bit is used to indicate read/write, the other 7 bits are the real address data. Sometimes this is listed as a straight 8-bit number with the LSB set at 0, and sometimes it is shifted one to the right to get rid of the LSB (you can see that 0x40 is 0x80 shifted to the right by one). The Arduino Wire library expects the 7-bit format, but address registers may need the 8-bit format. Bleh.<br>
Also note that some I2C chips have ways to slightly alter the address if there's a conflict. This one lets you use an input pin to change the LSB of the address, which should solve your problem. See page 54 in the documentation for details.</p>

I looked for an updated datasheet but there is none, or has bosch falsely manufactured some of these nice chips with wrong addresses for some time? the main problem in my project was i had another sensor (SDP-600) that unfortunately had the same address :(</p>
