3.2.3 AT Command
A command starts with the 2 ASCII characters: «AT», followed by one or more characters and data (see the list below for the syntax of the AT
commands available on the modem).
Each command must end with a “CR” or “CR” “LF”, both are acceptable. (CR indicates: Carriage Return, LF indicates: Line Feed).
Once the command has been received, the modem returns:
• Data” <cr> <lf>, for ATS type playback control <n>? AT/S or AT/V.
• O” <cr> <lf>, for all other commands when this has been accepted.
• “E” <cr> <lf>, if it refuses the command due to a syntax error, unknown command, unknown register, invalid parameter, ....
• “CM” <cr> <lf>, if it accepts the input in command mode

Interpretation of the example above: the user wanted to modify the beginning of the APP_EUI after entering an unauthorized command (answer
E), the registers were unblocked to modify the register. The second part of the APP_EUI was verified and the parameters were saved before
exiting. When exiting command mode, the device will send a JOIN request.
