Hi,
I tried to use the sensors on the Thingy:53.
However, it looks like the BMI270 on the Thingy:53 is not supported by the nRF Connect SDK because the SDK only supports the I2C mode of the sensor but the Thingy:53 is using the SPI as interface.
Please update the SDK to support the Thingy:53 BMI270 sensor.
Best regards,
Markus
