Is there any AT command to know whether the Xbee is coordintor or router using ?

I’m using Xbee PRO S2 for my project ,for that i need to know ,whether the Xbee module is Coordintor or Router using AT Commands. But, I cant find any commands in the Xbee PRO user manual.

You can check the firmware version. For S2 it will be different for coordinator, router, or end device. For instance, the latest firmware for S2 is:

coordinator api - 21A7
coordinator at - 20A7
router api - 23A7
router at - 22A7
end device api - 29A7
end device at - 28A7

As you can see above, it is the second digit that distinguishes which device.

Try the VL command.
