the linkage between coordinator and router in XCTU switch to network working mode

From Coordinator to router,
the quality: 255 LQI
Status : Active

When router to coordinator,
the quality remain the same : 255 LQI
but the status show Inactive

so whats is the problem? or is it ok if the status is inactive?

Sorry for my poor english!

That is fine if the link is inactive. It just means that it is not being used at that time.

oh!Thx u very much!^^
