I have 3 XBee modules out of that 1 was set as coordinator and other 2 are end devices.I want to reset this modules externally,by connecting external circuit by using hardware timer or watchdog timer or any other way.
It is possible? If yes then how?which component needed for that? how to connect it?
You mean reset module parameters to factory defaults or change Coordinator/End Device firmware to Router or something similar? This can be easily done by XCTU software. You can connect module with system using an interface board (eg:Digi’s XBIB-U board).
For the experiment which models I used this are specially designed for RF energy meters.So it is difficult to me to detect its configuration.This models not support the XCTU software.
I want only reset this zigbee module by eternally connecting timer or other component. this is possible?
If yes then how?
