I have a brand new XB24-ZB and it has stopped responding to X-CTU after I tried programming it.
I know it is not my programmer because I can use another XB24 in it and the comms work fine.
The ON/SLEEP signal is strobing on/off at about 1 second on, 5 seconds off and I think this is part of the problem. If I send a +++ when it is not in SLEEP mode then the device stays ON for about 25 seconds or will stay on for as long as there is data being sent to the device.
The trouble is +++ does not put it in command mode.
I have tried a couple of different baud rates (I only played with 19.2 and 9.6kbps) to no avail.
So I think I have two problems. One is it is going to sleep mode and the other is I have put it in a mode where itis not talking to X-CTU.
All help appreciate.
