Hello,    I need to correct my answer. The limitation of read wrtie length is only for bma456h, so it's not your case.  You can use it 2048 bytes, 6144 bytes as well.  Let's check step by step. After bma4_write_config_file function calling, did you get any error?  Could you capture your data and upload it?  I'd like to check whether your burst write function can tranfer properly or not.  Reading chip_id is only required signle byte, so you can't check it.  Thanks,    ...

Hello,    One thing I'd like to mention that the ODR range for performance is from 12.5 to 1600, and the ODR range for low power mode is from 0.78 to 400.  No motion and any motion should work in low power mode as well, but you should consider how it works.  Regarding any motion, the idea is if the data is over the threshold and it keeps over duration, any motion interrupt is generated.  No motion is vice versa.  If ODR is slow, it takes longer time for duration therefore you have to modify duration value.  If you are using github API, you can check in bma456h_feature_enable. BMI270 datasheet has detailed information about anymotion and nomotion.  https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bmi270-ds000.pdf Please let me know if you have any quesitons.  Thanks,  ...

Hello,    Yes, you have to inlucde BSEC library in your platform.  In terms of LPC845, we don't have exact instruction, but below url could help you.  https://github.com/BoschSensortec/BSEC-Arduino-library There is some information about library setting.  Please let me know if you have any quesitons.  Thanks,    ...

Hello,    I don't understand what you mean "I had to set dev.read_write_len = 2048 because out target's DMA cannot handle the complete config file burst write." You mean that your system can't send DMA memory sequencely? ( 0 ~ 15, 16 ~ 31 bytes for 16 bytes each) Thanks,  ... View more
