XBee S2C (XB24C) Router-Coordinator Dont send or receive any message

Question

I have 2 XBEE S2c module like these -> Modules

I installed XCTU latest software from the internet and set one of the XBee is router, other one is coordinator. I gave them exact same id 4444. After looking tons of website i couldnt communicate them. My friend got same XBees and i used those configurations but still not working. Is my XBee Modules are broken?

Here are the settings;

For Coordinator: https://ibb.co/album/7QmcR0

Terminal Example ( Coordinator Send and Receive at the same time but Router dont sending or receiving anything. )
Terminal 1
Terminal 2

They both connected to the computer like this; Connection

I look for a solution in all websites, and tried everything but did not find anything useful. With same configuration my friends devices can able to communicate but mine doesnt.

Answer 1

Problem 1:

this is exactly my problem (Connection related between Coordinator - Router)

***Note : Kindly Check Firmware Version

if Version is greater than 4060 then downgrade to 4060***

i don't know the reason

i downgraded to ver 4060 then it works ...

and most important Change AP (API Enable) to 0 (Transparent mode)

And Config guide -- > For Co-Ordinator (Suggestion From Robu.in) 1: First set Pan ID for your network. This can be any Hex value from 0 to FFFF. (Set it as 1234)

2:To operate the Radio in the broadcast mode set the DL (Destination address) as FFFF.

3: Type the name of the first radio in NI (Node Identifier).

4:You can provide any name. Here the NI set as COORDINATOR.

5:To make the Radio as COORDINATOR, Set the CE parameter to Enable and click on the Write button (Pencil Icon) to save the information.

Config Guide --> For Router

1:Enter the Pan Id [Same as Coordinator] which is the same as COORDINATOR.

2:Set the JV channel Verification to enable so that it joins the COORDINATOR.

3:Leave the CE to Disable and click on the Write to save the changes.

That's It !

now Check Serial Communication ...

Problem 2: (My Suggestion [cause it happened with me also])

and for [Coordinator Send and Receive at the same time]

Check COORDINATOR Config DL (Destination Address) -> Set to FFFF
