XB24-B ZNET can't change channel number

Hello.
I have two XB24-B ZNET 2,5, one is configured as COORDIANTOR and the other as ROUTER/END DEVICE.

The PANID on both I set to 666
The BAUD RATE to 57600.

the xBee want communicate to each other.

The channel of the Coordinater is set to 14 (0x0D) and the Route/End Device is set to 0.

I suppose I have to change the channel number to get the connection to work. But how do I do it?

Kind regards Martin

You don’t need to match up the 2 channels - the coordinator selects a channel and the ‘router’ will find it.

You want to make sure the “SC” setting on both match. This defines which of many channels the coordinator will try & possibly select (0x0D is the first one normally tried).

If the router isn’t associating with the coordinator, it is likely for some other reason, not the channels settings.

Thanks for your advice.
The SC setting on both modules are 1FFE (default).
I’m right if I plug in the ROUTER to a power supply (3,3V of corse) and in sending (with the X-CTU software) the ATND command I should get the reply of the ROUTERS NI?

My settings are:

COORDINATOR: (Firmware 1047)

ID E (PAN-ID)
SC 1FFE
NI COORDINATOR

ROUTER (Firmware 1247)
ID E (PAN-ID)
SC 1FFE
NI MARTIN

Thanks Martin
