How to configure S4S sensor synchronization in LSM6DSRX module

[farid]

The iNEMO inertial module LSM6DSRX supports sensor synchronization S4S for Qualcomm. Sensor data sheet mentions following S4S registers without much detail.

• S4S_TPH_L (04h) Sensor synchronization time frame register - low byte (r/w)
• S4S_TPH_H (05h) Sensor synchronization time frame register - high byte (r/w)
• S4S_RR (06h) Sensor synchronization resolution ratio register (r/w)
• S4S_ST_CMD_CODE (60h) S4S master command register (r/w)
• S4S_DT_REG (61h) S4S DT register (r/w)

Its not clear what values those S4S registers (TPH, CMD_CODE, DT_REG) should hold to function correctly.

Is there any application note describing how to configure S4S sensor synchronization on LSM6DSRX module.

Your help is much appreciated.

Hi @farid​ ,

Our devices support S4S which is a Qualcomm proprietary feature, which we therefore cannot document on ST apps. Please note that on ST datasheet is just reported state that it is supported. For a direct help, you should directly check with Qualcomm.
