SDK 14.2.0 support s132 v5.0.0 which has the exact same function: sd_power_ram_power_set(). The RAM Retention Example is also available.

Hi,

There is a RAM Retention Example in the SDK. If you are using softdevice, you either have to disable the softdevice before writing to the POWER registers or use the softdevice API sd_power_ram_power_set().

Best regards,
