Hi all, I am using the new Xbee SX 20mW modules to set up a network. We have one that has entered a strange state (It may have been due to buffer overun issues whilst issuing AT commands causing odd data to be sent). Anyway the issue is that I wish to issue an ATRE command but cannot get it to enter command mode.
The reason seems to be that it is spitting out ff characters constantly as soon as it powers up. This ( I think?????) is dominating the communications lines and preventing the +++ command from being executed.
I have tried minicomming into it and issuing the +++ command, I have tried XCTU and board repair (it reports no bootloader found), I have tried a reset by connection from reset to ground and then upload +++ but I am not quick enough. I have also tried putting pin 4 (DIN) to VCC on power up to try to enter command mode as per the manual. None of these methods is working for me.
Does anyone have anything else I can try to enter command mode, send the ATRE command and get the unit back under control? Would writing a script to bombard it with +++ and wait commands work?
Also does this sound like I have identified the issue that is causing command mode not to be entered or am I missing something more obvious or silly?
Thank you all for your help in advance!
