BMP388 Read Question

[Rutgers21]

Hello, i'm trying to get correct data from my BMP388 but don't seem to get the correct response from the device. I am using the standard bosch driver from GitHub.

I'm including the stream from my logic analyzer so you can see that I'm sending the correct command to initiate data transfer.

Is it normal for the first of each three data registers to contain 0x00?

For BMP388 SPI mode, when you want to read from sensor, you need to add 1 byte as dummy byte which means you always read N +1 bytes from sensor and first byte you read out is 0 as dummy byte.  Then useful data is following after the dummy bytes.
