edge impulse does not recognize the IM948 motion sensor

When Raspberry PI was able to communicate with IM948 serial port, I used the edge-Impulse-Linux-runner command, but the system kept replying to unknown sensors. However, I integrated IMU948 file code and edge impulse communication code to upload data. And it shows on edge impulse that I am currently unable to deploy the.eim file due to an inability to recognize the device

Hi @huawei

It is not clear how you integrated this sensor, you will need to explore our Linux SDK to add a custom sensor:

Looking to connect different sensors? Our Linux SDK lets you easily send data from any sensor and any programming language (with examples in Node.js, Python, Go and C++) into Edge Impulse.
