I am using an arduino based micro controller for interfacing with a programmable XBee PRO 900HP 200K. During setup I want to be able to set the Channel Mask, TX Power Level, Network ID, Sleep Mode, and some other AT Command Parameters.
This had been working for me earlier, but this morning all of my AT Commands began timing out and failing. Thinking it might be an issue with the arduino board I am using I switched to the Digi Dev board and XCTU to try communicating with the board.
I am able to detect the module (We'll call it ModA) through the com port and it shows up in the list of radio modules in XCTU. I am also able to find it as a remote module using a separate module (ModB). However, I am unable to read the radio settings of ModA when trying to read it through the COM port (AT Commands), but if I read ModA's settings through ModB (Remote AT Commands) I am able to read out all of the settings. To my suprise the radio was not set to sleep (SM=0), even though I had been previously setting it to pinsleep mode (SM=1)
Any ideas what is happening here and what may have changed to cause this behavior when it had been working fine last week?
