Dear All
We are at developing step in a GPS tracking device using SIM7600 SA modle with MDM9207 chipset and we noted after severals hour of use the GNSS lost Sat and sometimes lost all information and the modules makes a cold start , we noted at this situations that GNSS signals takes a lot of time for recovering (sometimes 40 min ) .The fluctuation of lost Sat is very erratic , sometimes work fine and sometimes lost sat , we tested this situations on Simcoms dev kit and also in our ouwn equipmets , someone have the same problems .....
Regards
