I am using the BME280 with a SPI communication to a STM32 chip. I am seeing the following crosstalk of the clk on the miso (dont mind the ringing):
I dont see this when the sensor is disconnected. I isn't an issue for the communication, but i was wondering what the sensor is doing there.
Kind regards,

We didn't see such effect from BME280 on other MCU platform.
Can you paste your schematic for BME280 also? if possible, the layout around BME280 is also preferred.
And i want to ask in which working status of BME280 you see this cross talk. is it just power on BME280 or put BME280 into normal mode?
