  • Hi,
    I got informations from systraq about power modes:
    “Low power mode uses 2 search engines (peak current ~50mA), enhanced acquisition mode uses 4 search engine (peak current ~70mA). Latter is faster acquiring weaker signal. Not much difference in TTFF if open sky signal 40dB or higher."
    In enhanced mode, I got cold start in 20 to 40 sec (average 28s), hot start 1s, with some exceptions (one 80sec cold start and one 3sec hot start). Tested with eval board and active antenna in a quite bad environment.

No public wish lists :(
