Battery
The Tetra IoT Agent Box takes a CR1220 battery to maintain the clock when the device is powered off.
NOTE
If the battery is discharged or missing, the system clock will reset when powered off, which can prevent connection. To check if this has happened and reset the time, see step 5 in the Configure Tetra IoT Agent Box procedure.
Network Specifications
The following lists the network specifications. Note that \<TDP domain\> is the Tetra Data Platform endpoint you log into (for example, platform.yourorganization.com).
| URL | Port | Protocol | Description |
|---|---|---|---|
| iot.<TDP domain> | 8883 | TCP | MQTT+TLS (Outbound firewall rule from IoT Agent (Client) side) |
| iot.<TDP domain> us.pool.ntp.org * north-america.pool.ntp.org | 123 | UDP | NTP servers for time synchronization; at least one NTP URL should be allowed; if on LAB LAN, an internal time-server needs to be configured in IoT Agent local settings to allow for automatic time sync upon Agent reboot. |
MQTT
The Tetra IoT Agent uses MQTT+TLS as the main communication protocol. Communication includes the following information:
- Data collected from devices/sensors specified in the driver and configuration file
- System metrics of the Tetra IoT Agent, including the following: SSID, MAC address, and IP address for WAN and Wi-Fi
- BSSID, signal strength, and quality for Wi-Fi
- New configuration file from the cloud
- Firmware update to the cloud
