The resistor R17 is not populated in the design. We are using I2C address 0x29. Please refer the updated schematic. ... View more

Hi, I have also tried measuring with meter connected to the GND side and by disconnecting the INT pin from the external application MCU but still my power consumption remains unchanged. ... View more

Hi, By Host MCU do you mean an external application processor reading data from BNO055 or the Cortex-M0 processor which is internal to BNO055? I think I got confused when you replied earlier. Please clarify. ... View more

Hello, So is this problem with a specific batch of chips or all the new chips have similar problem? Because earlier in this thread I could see the other bosch team could achieve 40uA power consumption in suspend mode on the BNO055 shuttle board. And is there any kind of workaround or firmware upgrade which can fix this issue? Further I would also like to know whether you recommend this part for future products because we are already facing issues with this one in the existing product while calibrating the sensor and with power consumption. We are also planning new products with the same sensor so if you have any alternative please suggest. Thanks for your reply. ... View more

Hi Moderator, I checked with the hardware team and they made it clear that the 0 ohm resistor on BL_IND pin was not populated on any of the boards while we did the current measurements. Also as per your recommendation, they have increased the capacitance on pin 9 from 100nf to 1uf still the result remains unchanged and the board consumes around 168uA in suspend mode. Please let me know your comments on this. ... View more
