6. AT commands
6.1. Description
• AT commands are only interpreted when the transmitter-receiver is in command mode.
• The commands are used to read and update the modem’s parameters:
• A command starts with the 2 ASCII characters «AT» – «AT means «Attention» – followed by one or more
characters or other data.
• Each command terminates with a <cr> (carriage return).
• In the same command, the length of time between two characters must be less than 10 s.
NOTE
When it receives a correct command, the modem responds:
• «O»<cr> (ASCII character 0x4F) in order to accept the command (command OK).
• «E»<cr> for an error.
• aspecicstringonrequest.
6.2. The command set
Commands Description
Selecting operating mode

Register management
ATSn? Displays the contents of the register Sn, where n
represent the number of the register.
The response will be in the following format:
Sn=y<cr><lf>
ATSn=m Assigns the value «m» to the register Sn; n represents
the number of the register.
AT&W SavesthenewregistercongurationintheEEPROM.
Each time you activate the modem, the EEPROM
congurationwillbeloadedintothemodem’sregis-
ters.
AT/S Displays all the register values. The response will
have the following format: Sxxx=y<cr><lf> for each
register.
AT/V Displays the software version. The response will
have the following format: Adeunis-RF_ARFx3-
PRO_868MHz_500mW Vxx.yy<cr><lf>
ATR Restores the default register values.
ATPWD=m m = pin code (register S205): unlocks all the AT com-
mands.
m = 0000: sets the register to the default value and
unlocks all the AT commands.
Test modes
ATT1 Pure carrier transmission (data=0) on the current
channel. This mode is exited by receiving any charac-
ter on the serial link.
