Is there any software which I can install on computer and see all the zigbee routers/end-points. Do detailed range test, channel study etc. I know about XCTU which have range test functionality but its does not provide the any info on channels etc.Many software’s are available for Wi-Fi like XIRRUS but not found any one for ZigBee.
It sounds like you need a Zigbee Sniffer. This is not something available from Digi, however a quick internet search will turn up several third party options.
They range in cost from about $50 and up into the Thousands. Just remember that you get what you pay for in these programs.
