I have a pair of XBee series 1 modules (XB24-AWI-001 to be exact).
I was able to recognize the modules in X-CTU only a couple of times. I have tried doing so like a hundred times and also tried checking all search options (Baud Rates, Flow Control, etc), but the XBee only gets recognized by luck.
I tried using CoolTerm to open a connection to the appropriate COM port with the appropriate baud rate, etc, but the module does not respond with an OK to +++.
I tried recovering the XBees but the process either fails when it asks me to reset the module (which I do, by shorting RST and GND), or it fails at some PutData error.
I know the modules are not faulty since I was able to recognize them once. How do I bypass X-CTU and work solely on a serial console using AT commands? I know there are three different modes (AT, API1 and API2), any way I can detect the mode of operation or just take the module into AT mode?
Lastly, what's the difference between transparent mode and command (AT) mode?
Any help is highly appreciated.
