Reconnection Mechanism


Function description: When the device is in TCP_Client/MQTT mode, this mechanism can be enabled to protect traffic.


In actual applications, you may encounter remote server abnormalities or business needs that cause frequent disconnections. In order to ensure that the ZHL4921 is always online, it will continue to try to establish a connection, which will cause unnecessary traffic consumption. When disconnected, ZHL4921 will first try to connect according to the "reconnection times". If the connection is still not confirmed, ZHL4921 will enter the waiting state, and the waiting time is the set "interval between reconnection tasks". After the waiting time expires, ZHL4921 will try to establish a connection again.

 

GPS Positioning Function
Function description: ZHL4921-G version supports GPS positioning. Please choose whether to enable this function according to the device model.
Note: After the GPS positioning is turned on, the GPS antenna is required in the open air to obtain the GPS positioning information.

The GPS information is the WSG84 coordinate system. Please convert it according to your needs.
