3.3. Description of the registers
On start up the device operates according to the last saved configuration (Factory Configuration if it is the first start up, or if this configuration
has not been changed).
The IoT Configurator or a change command of the type ATS <n> = <m> allows you to change the content of the registers: <n> representing
the register number and <m> the value to be assigned. The latter is either a decimal value or a hexadecimal value consistent with the «Encod-
ing» column of the tables below.
As examples:
• ATS300 = 6 assigns the decimal value 6 to the 300 register
• ATS302 = 2 assigns hexadecimal value 0x02 to register 302
It is imperative to save the parameters by the command AT&W before exiting the Command mode otherwise all changes will be lost.
IMPORTANT: Undocumented registers (which may appear in the list following the AT/S command) in the following paragraphs are reserved and
must not be changed.
3.3.1 Function registers
The list of registers below allows you to change the behavior of the device application
3.3.1.01
General registers
Register Size (bytes) Description
Encoding Details
S300
2
Transmission period of the Keep Alive
frame
Decimal
Default: 8640
Min/max: 2 to 65535
Unit: x 10 seconds
The value of 8640 equals a period of 24 hours.
S301
2
Number of backups (history logs) to be
done before sending a frame (thus defin-
ing the transmission period)
Decimal
Default: 1
Min/max: 0 to 65535
The value 1 equals 1 frame sent for each backup. The value 0
is equivalent to disabling the periodic mode.
See note below
S304
1
PIN code
Decimal
Default: 0 (disabled)
Min/max: 0 to 9999
PIN code used with the ATPIN command.
A value of 0 disables the PIN.
S306
2
Operating mode
Decimal
Default: 0
Switches the device to one of the following modes:
• 0: PARK mode
• 1: PRODUCTION mode
• 2: Reserved (do not use)
• 3: REPLI mode
S308
4
LED activity
Hexadeci-
mal
Default: 0x4007F Other possibility:
0x00000070: disable LEDs except low battery activity, REPLI
mode and faulty device
S320
2
Number of polls/readings to be per-
formed before saving in the history logs
Decimal
Default: 1
Min/max: 1 to 65535
The value 1 is equivalent to 1 backup per reading
S321
2
Period of acquisition (of poll/reading)
Decimal
Default: 1800
Min/max: 0 to 65535
Unit: x2 seconds
The value 1800 equals 1 hour (1800x2 / 60/60)
* The PIN code protects the device configuration. After 3 incorrect attempts the device is blocked.
Caution: in order to give more freedom to the user the device has not been limited to a maximum number of backups per frame depending
on the network used. We therefore strongly recommend not exceeding the maximum number of readings authorized by the network if you
do not want to lose data (the oldest readings will be overwritten in favor of the most recent ones). If this occurs, an indication is given in the
data-frame byte status (explained in section 4.1.8).
