s132: disable calibration for LFRC

Hi all,

Is there any way of running s132 with LFRC without having the SoftDevice calibrate the oscillator periodically? If there is no "official" way, can I bodge it somehow? I'm using s132 v5.0.0 together with nRF5 SDK 14.2.0 on an nRF52832 DK.

I know this is a weird question, but I'm shoulder deep in an application using the timeslot API based on LFRC, and disabling LFRC calibration would help shed some light on the properties of the drift I'm seeing. I don't need the SoftDevice to guarantee ±500 ppm accuracy, but I'd prefer if the drift was only dependent on ambient conditions and not on the SoftDevice calibration routine. As it stands, the drift seems to change direction slightly every time the SoftDevice finishes calibrating the oscillator.

This application is part of my master's thesis, and I am unfortunately unable to provide more information. I hope you understand. Any help is greatly appreciated.

Best,

Fredrik
