Directory for TCS navigation objects
TeleCommunication Systems, Inc. (TCS) provides a navigation engine that we have shipped for your reference. When you install the TCS product, it creates the /pps/tcs/ directory along with these subdirectories:
The HMI uses only two of those directories:
/pps/tcs/ccc/—contains the objects that TCS uses for status updates, which the HMI reads.
/pps/tcs/hmi/—contains a control object that the ASR module uses for navigation and POI search commands.
The HMI listens to these objects:
/pps/tcs/ccc/control—contains navigation and POI search commands.
/pps/tcs/ccc/nav—contains navigation session data.
/pps/tcs/ccc/qck—contains summary of current status.
/pps/tcs/ccc/control—contains responses to the commands sent to the /pps/tcs/ccc/nav object.
Command | Data type | Description |
---|---|---|
{"start":"navigate","param":"<destination>"} | JSON | Start navigating to the specified destination. |
{"start":"search-place","param":"<keyword>"} | JSON | Start searching for the specified place. |
