7.1.3 GENERAL CONFIGURATION
Please follow below steps to configurate the device:
1. The first step of configuration is to get authentication to perform any configuration changes. Query security authentication
using AT+SECAUTH? If Security policy is set to 2 or 3, get authentication with AT+SECAUTH = 1,<authorization password>,
else send AT commands without any authentication.
2. Next, set device configuration version using below AT command to identify and track your different configuration details.
AT+CFGVER = <major>.<minor>
By default, Configuration version is set to 0.0 and device is considered in the FACTORY Power State. When device is in
Factory Power State, device will automatically transition to Full Power off state after 4 hrs. To get more details on ST150
Power management please refer to Section 3.1 Power Management High Level Overview.
Set configuration version to non "0.0" version to transition device power state to configured live-state and to avoid automatic
power off. To query the version use
3. After setting the configuration version, configure all required parameters of respective component using configuration AT
commands. These changes are saved in volatile storage of device.
4. To save configuration settings changed in step 2 to non-volatile storage i.e., Flash storage of device commit operation must
be performed using below command:
5. To have the device to perform with all configured setting, do system reboot
with new configuration settings on startup.
6. A factory reset operation can be run to restore all settings back to factory reset settings. The AT command
AT+FACTORYRESET
device. In case of factory resets steps 3 and 4 can be avoided.
7.2 URC NOTIFICATION SETTINGS
URCs can be enabled for each module to allow asynchronous notifications of these system events through external interfaces,
such as UART, Nordic UART Service (NUS) and CONFIG Service allowing an integrator to customize their application from an
external source.
The following events support configurable notification events:
1. Transmitter
2. Transmitter Queue
3. General Purpose IO
4. Inputs Count Event
5. Track events
6. GPS module
7. Accelerometer
8. Power Management
9. Logging component
10. OTA Events App
URCs for supported component events can be enabled for visibility from external interfaces using following AT commands.
