    After a couple of days of testing with the provided brick Temperature sensor, during which it worked flawlessly, I noticed something wrong with it: now, most of the time, the temperature register 0x00 becomes unreadable, i2cdump shows "XXXX". Also, the configuration register becomes not writable sometime: I got a write error a couple of times from i2cset command, while other tries were successful.
    At the same time, from a Python script I used to read and store values in a csv file, I get "Error accessing 0x48: Check your I2C address" most of the times.

    Someone else has experienced this issue?

    I also noticed that after trying to connect another I2C device through the external pinout, without success, I see now another address occupied with the command i2cdetect: address 0x6f, while the temperature sensor has address 0x48, and the other I2C device I was trying to connect, which is not connected now, had address 0x68.

    Is there the possibility I messed up something with I2C bus? Maybe a collision of some kind? What's due to the address 0x6f I see now connected on bus I2C2, together with the temperature sensor?
    Any suggestion appreciated, thank you
