I manage a Xbee network with 30 end devices, two routers and one coordinator.
Six of these 30 end devices are LT sensors working in extended sleep mode: They sleep for five minutes and then wake up for sending one sample of temperature.
Some weeks ago I replaced one of them because each certain time it was not able to send data, even being at the side of another LT sensor working right, so I discarded out-of-range problems.
After installing the new one and configuring it according to the Digi wiki, and after being working right for some days, now the device is unable to send data. If I open the coordinator interface I can see how the device is added to the list in two minutes aprox. (it wakes up every two minutes), but I’m not able to get any data from it both by clicking on in in the coordinator interface or by resetting the coordinator.
The sensor configuration is:
DH,DL: Coordinator address
Special care has been taken when configuring coordinator and routers:
Firmware in the coordinator and routers is version a7, firmware in this end device is 2ca7.
I am really tired and frustrated with LT sensors in sleep mode. After one year fighting with this network I’ve not been able of keeping all the LT sensors working joined for more than one month.
Please, what I’m doing wrong?
