ST com Teseo-LIV3F Tiny GNSS Module
Introduction
- Teseo III – Binary Image and Teseo Modules embed also the Data-Logging sub system
- Data-Logging can be used to track/record a path
- Data-Logging subsystem has a set of specific NMEA commands and messages to operate
Create a log
A log is created to specify:
- Configuration
- Log type
- Lowest speed, lowest rate and lowest distance to record a new sample in the log
Start, stop and delete a log
A log can be started, stopped and deleted by the host with the following commands:
Query the data-logging state
- Host can query the datalogging subsystem state with the command:
- Teseo III replies with the message:
- Where it reports:
- Time and date of the first and last sample*
- Number of used and free entries
- Buffer status
- Host can query the log with the command:
- Teseo III replies with one message per sample:
Putting all together
Using the Teseo-Suite, the Host can send the commands and check the Teseo III message responses.
- HOST > $PSTMLOGCREATE,1,1,0,0,1
- T3 < $PSTMLOGCREATEOK*5E
- HOST > $PSTMLOGSTART
- T3 < $PSTMLOGSTARTOK*1A
- HOST > $PSTMLOGSTOP
- T3 < $PSTMLOGSTOPOK*42
- HOST > $PSTMLOGREQSTATUS
- T3 < $PSTMLOGSTATUS,084126,20181128,084146,20181128,21,0,43627*67
- HOST > $PSTMLOGREQQUERY,084127,20181128,20
- T3 < $PSTMLOGQUERY,1,1,084126,20181128,3,2,1,37.441792,15.060400,0.0,0.0,0.0*0c
- T3 < $PSTMLOGQUERY,3,1,084146,20181128,3,2,1,37.441792,15.060400,0.0,0.0,0.0*09
- HOST > $PSTMLOGERASE
- T3 < $PSTMLOGERASEOK*1A
Take care of
The first field in the $PSTMLOGQUERY is a bitmap which specifies:
- 2b00: No more data, and the data in the message is invalid
- 2b01: more data available, and the data in the message is valid
- 2b11: No more data available, and the data in the message is valid
