Synchronize the Time Automatically Through a LoRaWAN^® Network Server

Prerequisite: The LoRaWAN^® network server supports the device time synchronization feature.

Steps:

1. Set the LoRaWAN^® version of the device to V1.0.3. For details, refer to Configure LoRaWAN® Parameters.
2. Connect the device to the network server. Once the device successfully joins the network, it sends a MAC command to query the time from the network server.

Note:

• This only supports getting the time, but not the time zone. The time zone can be configured by ToolBox App or downlink command.
• The device will send the DeviceTimeReq command every 5 days since the last sync.
