nano33 ble sense download model

Which data source should I use for my Nano33 BLE Sense board?
No idea what is the difference between Arduino BLE AccGyro, Nano 33 BLE IMU and Nano 33 IMU Serial? These three data sources have the same sample rate 119.

Is there any connection between the ENABLE_LPSD macro or other configuration macros in the Fw_global_config.h file?

All three options use the same IMU sensor on the Nano 33 BLE Sense. The difference is only in how the data is sent or accessed, not in the sensor itself or the sample rate.

Arduino BLE AccGyro
Streams accelerometer and gyroscope data over Bluetooth Low Energy. Use this if you need wireless data streaming to a phone or PC.

Nano 33 BLE IMU
Reads IMU data over USB/serial using the standard Nano 33 BLE IMU library. This is the best option for wired use, local processing, or machine learning projects.

Nano 33 IMU Serial
Also uses USB/serial, but outputs data in a simpler or legacy serial format, mainly for quick tests or basic plotting.

Which one to choose:
Wireless use → Arduino BLE AccGyro
Wired, reliable, or ML use → Nano 33 BLE IMU
Quick testing or simple serial output → Nano 33 IMU Serial

The 119 Hz sample rate is the same because it’s set by the IMU configuration, not by the data source.
