DRGN-27788: Bluetooth LE disables RRAM low-latency mode when using AXON NPU and Bluetooth LE simultaneously on the nRF54LM20B SoC
27+
When running AXON and Bluetooth LE together on nRF54LM20B, Bluetooth LE might disable RRAM low-latency mode during radio activity, which may slow or corrupt an ongoing inference.
28+
MPSL sets STANDBY mode in ``NRF_RRAMC->POWER.LOWPOWERCONFIG`` at the start of each radio slot and restores the application init value at the end.
29+
In a power-optimized application, if the radio slot ends while an inference is running on Axon, the low-power (``NRF_RRAMC_LP_POWER_OFF``) value will be forced by MPSL, slowing down the rest of the inference.
30+
31+
**Workaround:** Use ``CONFIG_MPSL_FORCE_RRAM_ON_ALL_THE_TIME`` to keep RRAM permanently in STANDBY mode.
32+
This setting increases power consumption but ensures reliable performance.

**Affected platforms:** nRF54LM20B SoC
