I'm using modules Xbee S2C PRO Zigbee to make a wireless sensor network, it is already with a newest firmware version (4061). The end-device module is measuring temperature through ADC Reads. It has IR selected on a great value 10s, for the module send to the coordinator just one time. In the network I have also a router and one coordinator that is conected to a computer, that reads data through serial communication.
The parameters of all modules are the same:
SP=AF0 (28s) is the maximum
SO=2 on the end device (is not using SO=4, because Digi's Technical support recommended SO=2, due to doesn't happen data loss.
The module seems to work great at the beginning, but after some time, just receiving the data samples, the communication looks unstable.
Some periods it results on more than one hour without receiving any messages, but after that, the end device sends a node identification fram and starts all again.
This is a critical application, I can't loose 1 hour of data.
I am already in contact to support of Digi, but due to the critical time I decided to write a post here too.
Does anyone had some problem like this?
