Hello,
I am implementing the periodic search for lte managment (using SDK 2.5.2 on a nrf9160).
The periodic configurations in struct lte_lc_periodic_search_cfg is:
.loop = false ;
.return_to_pattern = 0;
.band_optimization = 1; (data_profile = LOW_POWER)
And two following pattern :
- The first is range pattern type, with values : initial_sleep = 10, final_sleep = 40, time_to_final_sleep = -1, pattern_end_point = 1
- The second is table type with values : val_1 = 30, val_2 = -1, val_3 = -1, val_4 = -1, val_5 = -1
All periodic search tests are carried out using a Faraday cage, and network activity is measured with an ampere meter.
When the network is requiered, I received the event LTE_LC_MODEM_EVT_LIGHT_SEARCH_DONE , at next the modem switch to limited_service.
In the ampere meter, the periodic search works. Both pattern are executed with the right sleep values. However, at the end the search keep looping on the last pattern and never sends the LTE_LC_MODEM_EVT_SEARCH_DONE event. Even if a network was found, none event was delivred.
Why the search doesn’t stop and why the LTE_LC_MODEM_EVT_SEARCH_DONE event is never generated?
Thank you for your help
