XBee® 865/868LP RF Modules addressing

Hello,
In our previous project we used modules Xbee-PRO S2C in API mode to collect data from sensors. End devices send data to 0x0000000000000000 address. Now we are planning to use XBee® 865/868LP RF Modules, but it was found a lack of the possibility of sending data to coordinator by 0x0000000000000000 address. What is the best method to solve this problem?

You need to use the DL and DH function in conjunction with the SL and SH of the recipient. That is you need to use the receiving modules Serial number high and low as the source address and set your destination addresses to that serial number high and low.
