I attach at the following link an oscilloscope screenshot reporting the unwanted power consumption of XBee-Pro868 at each power up (power transmission 1 mW):
How can I take control of this unwanted behaviour? By using XCTU, lots of AT command reported in the manual are not implemented (e.g. JN, ND, DN,…) so I don’t know how to set properly my module.
The issue occurs using the sleeping node without any device connected at COM port (in the future I’ll connect a temperature probe). The problem is that XCTU doesn’t give me any possibility do disable the operation that causes this current consumption…
This sounds a great deal like you have a power issue where you are staving the radio while it is trying to wake up. What I would suggest is connecting it to an XBIB-U-DEV board and seeing if you have the same issue. If you do not, then it is a power issue.
I have just tested this with the information provided and I am not seeing what you are. My module is drawing around 0.08mA while it is in a sleep state and 58mA while it is awake. No change. I am using the default settings minus the SM 4 SP BB8 and ST7D0.
