RE: Reset Reason not indicating WDT Reset

Calling sd_power_reset_reason_get() prior to initializing the soft device was indeed my issue. Using nrf_power_resetreas_get() returns the values I expected, thank you for the help.

Hi,

The value of reset_reason is clearly invalid here. That is expected if you call sd_power_reset_reason_get() and sd_power_reset_reason_clr() before the SoftDevice is enabled. Is that the case? If not, can you show more about how/where this is called?

You will either have to wait until the SoftDevice is enabled when using this API, alternatively, you could also use nrf_power_resetreas_get() and nrf_power_resetreas_clear(), but note that in this case, you must make sure to only call nrf_power_resetreas_clear() before the SoftDevice is enabled.
