Can not communicate with FXOS8700CQ

Hi, 

 

I use FXOS8700CQ sensors as a slave and Texas Instruments MCU CC1312R as a master. There are two sensors at my board. The first one's address is 0x1C and the second's is 0x1E. When I debug my project, I need to use CPU Reset. After that I can not reach sensor that has address 0x1C. I tried to close I2c and open again, but I got same problem again. I did not get the problem with the sensor 0x1E. What can be the cause of this problem?

Hi,

 

Are there any changes on the RST and SA0/SA1 lines during your MCU reset?
