# AT Command
TC35i
<fun> parameter now accepts CYCLIC SLEEP MODE values
5, 6, 7 and 8, in addition to SLEEP MODE / FULL FUNCT.,
supported so far by TC35:
5 Reduced functionality (CYCLIC SLEEP MODE)
The serial interface is enabled with every "wake up". If
characters are recognized the serial interface will stay
active for 2 seconds (after last character).
6 Reduced functionality (CYCLIC SLEEP MODE)
The serial interface is enabled with every "wake up". If
characters are recognized the serial interface will stay
active for 10 minutes (after last character).Note: In any
case, any circuit switched calls will be terminated.
7 Reduced functionality (CYCLIC SLEEP MODE)
The serial interface is enabled with every "wake up". If
characters are recognized the serial interface will stay
active for 2 seconds (after last character). The sole
exception for wake up is at+cfun=1.
8 Reduced functionality (CYCLIC SLEEP MODE)
The serial interface is enabled with every "wake up". If
characters are recognized the serial interface will stay
active for 10 minutes (after last character). The sole
exception for wake up is at+cfun=1.
Additional notes
TC35i
• To check the current operation mode see „AT^SSYNC
Configure SYNC Pin", pg. 181.
• To check if ME has entered SLEEP mode it is necessary
to measure the supply current. SLEEP mode actually
starts after remaining network activities were
terminated.
• For SLEEP mode functionalities (<fun>=0, 5, 6) will
not work without PIN1.
• After reset it is necessary to enter PIN1 again.
• In SLEEP mode the device wakes up by incoming call,
short message, Real Time Clock alarm, falling edge of
RTS (RS-232 levels) and upon receipt of an unsolicited
result code (URC, see chapter 10.1.4).
• In CYCLIC SLEEP mode device wakes up by incoming
call, short message (only if notification output is
configured using AT+CNMI=1,1), Real Time Clock
alarm and upon receipt of an unsolicited result code
(URC, see chapter 10.1.4). RTS signal is only for
handshake and does not wake up the ME.
• In CYCLIC SLEEP mode 7 and 8 device wakes up by
incoming call, short message, Real Time Clock alarm
and upon receipt of an unsolicited result code but
continues the CYCLIC SLEEP after the event is
finished. Only with at+cfun=1 the system wakes up
permanently. RTS signal is only for handshake and
does not wake up the ME.
TC35
<fun> parameter accepts only values 0 and
1.
Additional notes
TC35
• To check that ME has entered the
SLEEP mode, it is recommended to
measure the supply current. Depending
on the configuration of the SYNC pin,
the SLEEP mode may also be indicated
by a status LED (see "AT^SSYNC
Configure SYNC Pin", pg. 177).
• When in SLEEP mode, the following
events may cause the ME to wake up:
incoming call, Real Time Clock alarm,
falling edge of RTS (RS-232, 2.65V
CMOS level) and receipt of an
unsolicited result code (URC, see
chapter 7.1.3).
84 AT+CGMI Request manufacturer identification
85 AT+CGMM Request model identification
86 AT+CGMR Request revision identification of software status
87 AT+CGSN Request product serial number identification (IMEI) identical to GSN
88 AT+CHLD Call hold and multiparty
89 AT+CHUP Hang up call
90 AT+CIMI Request international mobile subscriber identity
91 AT+CLCC List current calls of ME
92 AT+CLCK Facility lock
93 AT+CLIP Calling line identification presentation
94 AT+CLIR Calling line identification restriction
Differing implementation
TC35i
TC35i supports +CLIR as a proper AT command with
its own syntax.
TC35
TC35 implementation was limited to ATD command
with SS codes.
