Please check the baud rate, according to this post

> There is the solution !!! To increase the sampling The SER\_TEL2\_BAUD need to be increased. (which was 115200) The MAV\_1\_RATE need to be increased.(which was 0) PX4-autopilot automatically [half-size the data](https://docs.px4.io/v1.11/en/peripherals/mavlink_peripherals.html), if the communication is too low. P.S. In a serial communication system, the data rate is measured in bits per second (baud rate). However, it’s important to note that a byte consists of 8 bits. At a baud rate of 921,600, the maximum …

Because the baud rate in QGroundcontrol will limit the sampling rate of sensors.  
The default sampling of IMU should be 50 Hz
