Can xbee routers scan end device (in range) and get rssi value? is this possible with xbee? or Is there any other way?

Question

Can a router scan all (when in range) end devices and get rssi value?
For example:
There is one coordinator.(C)
There are 3 router.(R)
There are 3 end device(ED)
Now C can say me :
R1 get rssi value from ED1 : -90 dbm
R1 get rssi value from ED2 : -60 dbm
R1 get rssi value from ED3 : -80 dbm​

R2 get rssi value from ED1 : -40 dbm
R2 get rssi value from ED2 : -55 dbm
R2 get rssi value from ED3 : -89 dbm​


R3 get rssi value from ED1 : -23 dbm
R3 get rssi value from ED2 : -10 dbm
R3 get rssi value from ED3 : -70 dbm​

Answer 1

Yes you can issue remote AT commands from your various parent nodes to the specific end nodes requesting to provide the DB value.

Or you can use the S2C ZB module and use the ZDO commands to report the Link status.

Thanks. I wil try.

Hi, the rssi value is just the from parent nodes to the specific end device only? Is there possible to get the rssi value from nearby router toward end device?For example, i have 3 routers, and end device is placed in middle. However, end device is connected to one of them. So, i want to get rssi value for all routers toward end device but not only parent node. is that possible?

The RSSI is only available for the Last Hop. You need to get the LQI to know the quality of the link on each hop.

I examine ZDO commands but which one i must use?
