Hi, I’ve tried to update my Xbee modules using hardware flow control, but there’s a problem when doing it, the error msg was “module communications lost” or something similar, I´ve captured the communication using a protocol analyzer, and one error appears with the “AT%P1E58” command, I dont know this command and the module answer with “ERROR”. Maybe this the problem. After that, there is a ATFR command and begin strange commands with answers, but with “SIG FFSIGSIG” command theres no answer by the module… Any idea? Thanks. ---
