Description of the registers

Register values can be updated with the ATSn=m<cr> command and displayed with the ATSn?<cr> command.
On power-up, the transmitter-receiver's previous configuration is restored from the E2PROM (non-volatile) to
the RAM. The registers are located in the RAM registers, all changes are made in the RAM registers: in order to
save the current register configuration, the AT&W<cr> command must be used (otherwise the updated parame-
ters will be lost if the power is cut).
The parameters are divided into 2 types: read only (R) or read/write (R/W).

Function Description
Channel Radio channel for the 869 MHz version:
number 1 and 3: wide band channels
18 to 85: narrow band channels
Command Automatic exit from command mode 0: (no
mode auto- specific management), exit from command
matic exit mode only when an ATO command is
issued.
From 1 to 60: timeout in seconds.
-> if no activity (no character, no command
received) is detected in command mode
during the programmed timeout, the system
will exit command mode. The module
returns to transmitter-receiver mode.
Preamble Preamble length in ms from 4 to 50
length
Serial timeout Serial timeout before the start of radio trans-
for radio mission, in ms from 3 to 240
Radio frame Size of the radio frame (from 1 to 240)
length When the limit is reached:
• the transmitter-receiver sends a radio
frame
• the RTS signal is enabled only if the
module is operating in addressed mode
RSSI level Displays the reception level for the last mes-
sage received.
Response: S230=-xxx dBm<cr><lf> with xxx
