Xbee Broadcast retries

I am sending a broadcast packet from a Xbee pro s2c modules. I notice that over the air, the packet is transmitted 3 times (the original and then 2 packets 500ms apart roughly). Is there a way to disable the retries? I tried to send the option flag to Disable retries “0x01” but that didn’t have any effect.
Thanks in advance!

No, what you are seeing is part of the zigbee and 802.15.4 standards.
