Hello,
i'm having a problem with the satellite detection time when I start gnss search. When I start the search, for a while at first the satellites are not detected and then they start to be detected. The delay time is often distinctive. I'm currently using gnss in single fix mode with a timeout of 65 seconds. In the nrf_modem_gnss_use_case_set() function, I'm using the flags NRF_MODEM_GNSS_USE_CASE_SCHED_DOWNLOAD_DISABLE and NRF_MODEM_GNSS_USE_CASE_MULTIPLE_HOT_START.
Details setup:
Modem FW: 2.0.2
SDK version: 2.8.0
Board: nRF9161 dk
Below are some examples that demonstrate the problem described:
