  1. Dear All,

    I catch a problem while try to send a sort of commands to our LE910-EUG FW 17.01.522, Such that it hang and could not repond to any AT Command.

    I was trying to change the band after de reigter from netrwork, the back to select the network using autmoatic COPS command but it hangs and tried with manula COPS command but it failed.

    Attached the log file for testing.

    1. AT commands have published timeout values, +COPS timeout is 125 seconds. Try to wait longer for module’s answers.

        I waited for more than 20 min without send any command after +COPS and module hanged.
