when doing continuously sending data from cordinator to router data will be discard

i have 1 coordinator and two router. i am trying to create star network for our application. when i was send continuously data byte on coordinator using UART communication it was transmit properly.but on two router data packet’s will not received properly i.e.some time data byte will come after 1 or 2 second or some time data will discard.
if we send continuously data on the coordinator its router was in hang mode.

Rajashree,

The Zigbee Mesh Protocol is not well suited for a simple point to multi-point network as it needs to put in delays to allow for packets to be re-broadcasted out for multiple hops. Instead you should be using the 802.15.4 or Point to multi-point protocols on the 900 MHz products. These protocols are designed for doing what you are describing above.
