Click Export, then select the data time range to export data. The maximum export data period on ToolBox App is 14 days.
• Page 31: Data retransmission is supported to ensure that the network server can receive all data even if the network is down for some time. There are two ways to receive the lost data: - The network server can send downlink commands to enquire about historical data for a specified time range. - If the network is down and the device receives no response to LinkCheckReq MAC packets for a period of time, it will record data during the disconnection period and retransmit it after reconnecting to the network. Steps for data retransmission include enabling the data storage and retransmission features. Rejoin mode must be enabled, and the number of packets sent in LoRaWAN settings should be set. The device will send LinkCheckReq MAC packets regularly to check for network disconnection. If there is no response for 8+1 times, the join status will change to de-active, and the device will record a data lost time point.
• Page 32: After reconnecting to the network, the device will send the lost data from the point of time when the data was lost according to the data re-transmission reporting interval. If the device is rebooted or re-powered during the data retransmission process, the device will re-send interrupted retransmission data again after the device is reconnected back to the network. If the network is disconnected again during data retransmission, the device will only send the latest disconnected data. The retransmission data format starts with “20ce”, please refer to WT201 Communication Protocol. Data retransmission will increase the uplinks and shorten the battery life. Milesight D2D protocol is developed by Milesight and used for connection among Milesight devices without gateway. When D2D setting is enabled, WT201 can work as the Milesight D2D agent device to receive commands from Milesight D2D controller devices or work as Milesight D2D controller device to send commands to trigger D2D agent devices. Configure RX2 datarate and RX2 frequency in LoRaWAN settings. Enable D2D Controller Settings, and define a unique D2D key to be the same as D2D agent devices. Select any button to define a 2-byte hexadecimal control command (0x0000 to 0xffff).
