Hi All,
I have two the same sensors in my device. They work properly on one system but only one works properly on three others. Reason the same - no answer from sensor.
If I added reading from address 0xFF all stop working by the same reason. Power is ok.
What the reasons can cause dual behavior?
Solved! Go to Solution.

Hello,
Could you please elaborate more on how you are reading from address 0xFF ? Please send a code snippet of this.
Also, could you please do the swap test(take the failing sensor from the failing board and put it on a working board and see if it still fails) to see if the failure follows the senor or the board.
Please make sure that the pull-up resistors R1 & R2 of the I2C bus are set to recommended values provided in the Data Sheet.
Please check with triggering a general reset. A general reset is trigged by calling the address 0x00 in the I2C interface. This generates an internal reset, refreshes the fuse register settings and re-reads the SDA/ADR line to initialize the I2C bus address. Please refer to the 5.7.1 General reset section for more information.
Thanks,
P Yugandhar.
