Hi, Let's make BMP581 I2C communication work first and then try to read BMP581 pressure and temperature data. I have BMP581 shuttle board as well. The shuttle board is plugged onto APP3.0 base board at https://www.bosch-sensortec.com/media/boschsensortec/downloads/software_tools/application_boards/bst-dhw-fl045.pdf. Then I used DD2.0 GUI SW to set the APP3.0 base board to work at I2C interface with BMP581 7-bit slave address of 0x47. Then I use logic analyzer Saleae to capture the I2C transaction at https://www.saleae.com/. First I read BMP581 chip ID at register 0x01 and got the value of 0x50 back as shown below. This means I2C read is working. Then I write value of 0x60 to register 0x36 as shown below. Then I read register 0x36 again and got the value of 0x60 back. So it means I2C write is working. BMP581 I2C communication is straight forward. Please try to use a logic analyzer to debug. Thanks. ... View more

Hi, If you are using BMP581 shuttle board, then please tie VDDIO to VDD 3V3 and also tie CS to VDD 3V3 for I2C communication. BMP581 needs both VDD and VDDIO to ramp up and be stabilized at their operating voltage level so that it can start its power-on reset (POR). If you don't connect VDDIO to 3V3, then BMP581 is not powered on. Therefore, I2C communication will not work. Thanks. ... View more

Hi, Thanks for your inquiry. BHI260AP is soldered on Nicla Sense ME board that is compatible with Arduino at https://docs.arduino.cc/hardware/nicla-sense-me. You may purchase a Nicla Sense ME board and try some sample codes to get the quaternions and Euler angles outputs from BHI260AP. Thanks. ... View more

Hi, Thanks for your inquiry. To use BMP390 in an outdoor application the enclosure can not be sealed. You may consider to use a piece of Gore membrane for example GAW113 at https://www.gore.com/sites/g/files/ypyipe116/files/2017-01/GORE_PEV_DataSheet_AcousticVents_Dust_Splash.pdf to cover the vent hole of BMP390 or the hole of the enclosure of your product to prevent any contamination from getting into BMP390 sensor. Please refer to the handling, soldering and mounting instructions at https://www.bosch-sensortec.com/media/boschsensortec/downloads/handling_soldering_mounting_instructions/bst-bmp380-hs000.pdf when you design the PCB and enclosure.
