ZigBee communication -> sending messages from End-Device to Coordinator

[LKEPP]

Hello,
I got stuck developing with the nrf52840 DK Board, using the ZigBee SDK.

I´ve got a corrdinator, which establishes my network. Also I´ve got an End-Device that joins the network successfully.

The setup is pretty similiar to the example of the ZigBee light_control (light_coordinator, light_switch)

Now I want to send messages from the End-Device to the Coordinator. So I wrote my sending routine as shown in the picture. My problem ist, that I don´t know my coordinators adress.

How can I find out the adress of my router. Is there a specific macro that I can use?

Thanks for helping.

The short address of the coordinator is always 0x0000. This is defined by the spec.

Allright thank you.
