$ sudo tracker_config --status
{ "cfg_version": 5, "fw_version": 1, "unique_device_identifier": xxxxxxx, "cellular_module_present":

$ sudo tracker_config --reset FLASH
$ sudo tracker_config --reset CPU
5.9. Erase existing configuration
This command will erase all existing configuration settings held in RAM before proceeding with provisioning:
$ sudo tracker_config --erase
Now confirm the currently active configuration stored in RAM is "empty":
$ sudo tracker_config --read current_config.json
$ cat current_config.json
{
"version": 0,
# TBD: will this be the default version when the system is not programmed?
"logging": {
"fileSize": 0,
"fileType": "LINEAR",
"startEndSyncEnable": false
},
"rtc": {
"dateTime": "Mon Jan 1 00:23:40 2018"
}
}
