Thank you for your query,
Please note that start up time of FMB devices is not configurable. The hardware specifications are responsible for start up times and this can not be changed.
The start up times of GNSS module:
|Hot start||< 1 s|
|Warm start||< 25 s|
|Cold start||< 35 s|
The device will start sending data when connected to operator and depending on the configuration of "Records Saving/Sending Without TS" section. If the "After Position Fix" is selected the device will only send packets after acquiring GPS fix, this may take a longer period of time, depending on the available signal of the satellites.
Hope this helps,
