How measure rssi between endpoints ?
I need the endpoints of a zigbee network to read the signal to each other, is it possible?

You can get the LQI of received message and convert it to RSSI but not node to node RSSI.

OK, between end point and router is ok, but i can do this between endpoint to endpoint ?

Sorry, I actually meant end devices.

Zigbee end devices only communicate back to the parent router, not with other children, so in this regard it is not possible to measure the RSSI between them.

Traditionally this is not done, as most common applications do not have this requirement. I imagine there is no limitation on the hardware, since everyone can send and receive messages. Is it possible to write this function? without wanting to establish connection between them.

Since every end device can only communicate through its parent node, do you mean to know the RSSI of a specific end device receiving messages from its parent node from another end device?
