In order to get some more insights in energy consuming "network searches", I tried to keep track of the LTE_LC_NW_REG_SEARCHING and LTE_LC_MODEM_EVT_SEARCH_DONE events.
- LTE_LC_NW_REG_SEARCHING is mainly reported once at startup
- LTE_LC_MODEM_EVT_SEARCH_DONE seems to be reported on every PSM wakeup
According my question about some extra energy consumption nRF9160-DK - sometimes busy for 1 minute before entering PSM I would have expected, that one of the two helps to count such searchs, but for now, it's in vain.
Is there any other way then "measure the time to sleep" to count such "Higher Priority PLMN (HPPLMN) search"?
