OK
The attention code, along with all AT commands, is case insensitive.
MULTIPLE COMMANDS
Multiple commands can be placed after an
AT
provided that the total number of characters does not exceed
255. For example, a valid command to display the radio’s firmware version (
ATI3)
and internal temperature
(
ATI9)
is:
ATI3I9<CR>
This results in the output:
Firmware: 9256 Version 1.30 Rev.H Australia
25.5c
OK
S-REGISTER AND %-REGISTER COMMANDS
S-registers and %-registers are used to store complex configuration parameters. In order to set the value of
an s-register or %-register the following format is used:
ATS<r>=<n><CR>
AT%<r>=<n><CR>
Where
<r>
is the register, and
<n>
is the data. The current value of an s-register or %-register can be
retrieved through a command of the form:
ATS<r><CR>
AT%<r><CR>
A list of all s-registers can be found in Appendix C.2 on page 91, while all %-registers are listed in
Appendix C.3 on page 99.
RESPONSE CODES
Whenever an AT command is executed a response code is generated. Response codes can be either strings,
numbers, or be suppressed (not output to the serial port). The list of response codes generated by the RFI-
9256 is shown in Table 1.
