    Hi,

    I'm not sure what software the attached screenshot is from, but you can use a logic analyzer firmware to capture the logic traces of the I2C bus, for instance a Saleae (what I use). The Saleae software can decode a lot of protocols, like I2C, SPI, etc, and it can store the logic captures to file. If your software supports importing data from file, you might be able to import the traces.

    I'm not aware of any methods to do I2C logic captures using Segger Embedded Studio. The I2C/TWI firmware run on the nRF5x chip, not in the IDE on the computer, SES does not have access to the GPIOs of the chip.

    Best regards,
