XB24 Broadcast mode

Can someone tell me how to setup XB24 to broadcast mode and which firmware support it. I mean broadcast mode with no at command mode. I need configuration that sent received data by UART to all XBs nearby without preparing (without any AT command). Is this possible (first modules that I use were configured in this mode by default but I dont know version of that chips)?

You just set DL = 0x0000FFFF and DH to 0x00000000 (the destination address). A search of the 802.15.4 PDF manual for ‘broadcast’ brings up the relevant section.

I assume this only works with one of the “AT” firmwares, because with “API mode”, the destination comes in the API frame and the DH/Dl are ignored.
