Precision of the gyroscope

Thierry Benchetrit

From the Invensense documentation, the gyroscope can be configured to support range of ±250, ±500, ±1000, and ±2000°/sec

At present time it is configured to support range of ±250°/sec.

Do you know where to modify the firmware code of the sensortag 2.0 to change the default value ?

You check SensorMpu9250.c. If you install BLE Stack 2.2, it would be under C:\ti\tirtos_cc13xx_cc26xx_2_18_00_03\products\tidrivers_cc13xx_cc26xx_2_16_01_13\packages\ti\mw\sensors

I read this file again.

I can see a way to change the acceleration range : SensorMpu9250_accSetRange

But nothing concerning gyro range

I probably found the answer here

We have to use the GYRO_CONFIG like we do it with the ACCEL_CONFIG
I will try it when I will have a Debug Toolkit for my Sensortag 2.0

Yes, you have to do GYRO_CONFIG like that with the ACCEL_CONFIG.
