I am using XBEE3 pro module, created 3 networks with different channels and PAN ID, each network contains around 2 to 4 router devices (XBEE3 PRO. I have configured legacy network by creating coordinator for each network and other as no sleep routers. Now when I broadcast any data payload from coordinator, sometimes my data frame gets dropped, not getting data from master to any one of the node, it is not frequent. It happens sometimes, majorly it happens for broadcasting communication. What could be the issue.
Sending broadcast packets can only be sent once every 4 seconds. This is by design to allow for a packet to be properly re-transmitted thru a network. If this is more of a true point to point application, I would suggest using Unicast packets or switch to the 802.15.4 protocol.
