How to increase sample rare of the IMU (/mavros/imu/data)

[AlexWUrobot]

Although the QGroundcontrol the IMU rate is 800 hz

However the /mavros/imu/data is about 10 hz

I would like to inquire how to increase the sampling rare of the IMU (/mavros/imu/data)

Thank you very much

Hello!

I have the same problem with PixHawk. Did you manage to solve it?

Please check the baud rate, according to this post

How to adjust the sample rate of distance sensor (rangefinder)

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) [image] PX4-autopilot automatically half-size the data, if the communication is too low. [success_update_sampling_rate] [image] 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
