1 AT Command Overview
1.1 Document Purpose
This manual describes in detail the set of AT commands supported by the Azeus
Luat LTE module.
1.2 Conventions and terminological abbreviations
Modules may be referred to in this manual by the following terms: 1) ME
(Mobile Equipment), which may include Mobile Terminal (MT), Terminal Adaptor
(TA) 2) MS (mobile station), which includes the mobile equipment (ME) and the
subscriber identification module (SIM) 3) TA (Terminal Accessory) 4) DCE (Data
Communication Equipment) or Fax DCE (Fax Modem, Fax Board)
In the application, the controller controls the GSM module by sending AT
commands through the serial port. The controller at the opposite end of the
serial line can be referred to by the following terms: 1) TE (Terminal
Equipment) or 2) DTE (Data Terminal Equipment) or simply put, an embedded
application
Other terminological abbreviations:
AT
ATtention; this two-character abbreviation is always used to start a command line to
be sent fromTE to TA
BCD
Binary Coded Decimal
DCE
Data Circuit Terminating Equipment
DTE
Data Terminal Equipment
IMEI
International Mobile station Equipment Identity
ICCID
Integrate circuit card identity
IRA
International Reference Alphabet (ITU-T T.50)

1.3 AT Command Syntax
All command lines in this manual must begin with “AT” or “at” and end with a
carriage return (
1.3.2 S-parameter class AT commands
The format of this type of AT command is “ATS
1.3.3 Extended Class AT Commands
In general, extension commands can be classified into the following types based on their functions:
Command Type
vocabulary
instructions
test command
AT+
The command queries the parameters set by the setup command or internal procedure and their value ranges.
Enquiry command
AT+
This command returns the current value of the parameter
Setup Commands
AT+
This command sets user-defined parameter values
12 / 285
execute a command AT+
This command is used to read the non-variable parameters controlled by the internal procedures of the GSM module.
Extended class command syntax: In the command line TA return result, <> contains mandatory parameters and [ ] contains optional parameters; In each command, the optional and mandatory parameters must be listed in the specified order, and the parameters must be separated by commas; String arguments are generally placed in double quotes; In practice, <>, [ ] need not be entered.
Syntax for entering multiple AT commands simultaneously on one line:
Several AT commands can be entered on the same command line. This eliminates the need to enter “AT”
or “at” at the beginning of each command, and only requires that you enter “AT” or “at” at the beginning
of the command line. Please note that a semicolon should be added as a delimiter after the extended class
commands, while no semicolon is needed for the base class commands and S-argument commands.

4.10 TE-TA Local Traffic Control: AT+IFC
Introduction to Flow Control:
Flow control is important for reliable communication between the module and
the DTE. Assuming a data or fax call in which the sending end is sending
faster than the receiving end is receiving, when the receive buffer is nearly
full, the receiving end should have a way for the sending end to pause sending
until it catches up again. This is flow control.
Generally, there are two ways to implement flow control. They are software
flow control and hardware flow control. In multiplexed mode, hardware flow
control is recommended. Both methods of flow control are supported by the
HopZoo module.
Software flow control: The software flow control sends different characters to
pause (XOFF, decimal 19) and resume (XON, decimal 17) the data stream. It is
suitable for serial communication with only three wires.
If the Hopu LTE module uses software flow control, it needs to be configured
with the command: AT+IFC=1,1
Because this configuration is not saved, if you wish to continue to use
software flow control after a reboot, you need to save it to the User
Configuration Table via AT&W.
Note: When the module transmits binary/hexadecimal data, the software flow
control method is not
47 / 285
suitable because the TE may treat the binary data as flow control characters.
Hardware flow control:
Hardware flow control is implemented via the RTS/CTS signals. When the receive
buffer is almost full, the module sets the CTS signal to invalid and the data
transfer is suspended. When the module’s receive buffer can receive more data,
the CTS signal is reset to active. To implement the hardware flow control
feature, make sure your application serial port contains the RTS/CTS line.

Explanation of values
Disable the module sleep function. The module cannot enter the sleep state.
Default value. Sleep mode 1. controlled by the module AP_WAKEUP_MODULE pin to
enter sleep or not. When AP_WAKEUP_MODULE is pulled high (default is high
because there is an internal pull-up), AT+CSCLK=1 is set, and no other
interrupts are generated (GPIOs, incoming calls, incoming SMS, etc.), the
module automatically enters Sleep Mode 1. In this mode, the module is still
able to receive calls and SMS from the network.
When the module is in sleep mode 1, the module can be woken up by several
methods as follows.
51 / 285
The module receives an external interrupt signal; The module receives a voice
or data call; The module receives a short message (SMS); The serial port
receives the AT command; Pull down the AP_WAKEUP_MODULE pin for roughly 50ms
Note: URCs are reported when the module receives a voice or data call or short
message Sleep mode 2. After setting AT+CSCLK=2, the module will continuously
monitor the serial port data, if there is no data input on the module’s serial
port and no other interrupt is generated (GPIO, incoming call, incoming SMS,
incoming data, etc.), the module will automatically enter Sleep Mode 2 after 5
seconds by default. (Note: In the case of Sleep Mode 2, the level of
AP_WAKEUP_MODULE has no effect on the module’s Sleep Wake function. This is
the main difference with sleep mode 1). In this mode, the module can still
receive calls and SMS 2 from the network.
When the module is in sleep mode 2, the module can be woken up by several
methods as follows. The module receives an external interrupt signal; The
module receives a voice or data call; The module receives a short message
(SMS); The serial port receives the AT command. Sleep mode 3 (ultra-low power
consumption). After setting AT+CSCLK=3, the module will continuously monitor
the serial port data, if there is no data input on the module’s serial port
and no other interrupt is generated (GPIO, incoming call, incoming SMS,
incoming data, etc.), the module will automatically enter Sleep Mode 3 after 5
seconds by default. (Note: In the case of Sleep Mode 3, the AP_WAKEUP_MODULE
level has no effect on the module’s Sleep Wake function. This is the main
difference with sleep mode 1). In this mode, the module can still receive
calls and SMS from the network. 3
When the module is in sleep mode 3, the module can be woken up by one of the
following methods. The module receives an external interrupt signal; The
module receives a voice or data call; The module receives a short message
(SMS); The serial port receives the AT command.

Set to sleep mode 2. In this sleep mode, the module goes to sleep when the
following conditions are met simultaneously.
Module has no input on AT port No URC reported (including no incoming calls,
no SMS, no data
received from the server, etc.) No GPIO interrupt
Check the time to go to sleep
The query result is 5 seconds. 5 seconds is the default time to go to sleep
after CSCLK is set to sleep.
If you need to change the time to go to sleep, you can set it via WAKETIM,
e.g. change it to 8 (normally you don’t need to set it)
Note: WAKETIM should not be set to 0 at this time, as this will disable sleep.
The module wakes up in one of the following ways. 1) Enter several AT commands
into the serial port (one
often doesn’t wake up, you need to enter more than one) 2) Arbitrary URC
reporting (including incoming calls,
incoming SMS, data received from server, etc.) 3) GPIO interrupt

card on the SIM0 interface, it will read the card information on the SIM0
interface to register the network; If no SIM card is detected on the SIM0
interface, it will go back to detect whether there is a SIM card on the SIM1
interface, and if a SIM card is detected on the SIM1 interface, it will read
the card information on the SIM1 interface to register with the network; If a
SIM card is also not detected on the SIM1 interface, an error is reported: no
SIM card inserted; If SIM cards are inserted into both SIM0 and SIM1
interfaces, the SIM card on the SIM0 interface will be used by default, and

5.8 Carrier search and selection: AT+COPS
The set command is used to try to select and register a GSM/UMTS network
operator. is used to select whether to register automatically (
is ignored) or manually to (the value of is defined by
). If the manually selected operator is not available, then no
other operator is registered either, unless =4.
When =2, it forces an exit and remains in the exit state until is
set to 0, 1 or 4.
This command will not be executed if it is set when the network is being
cancelled or withdrawn.
The query command returns the current , the currently registered
operator , and the currently used Access Technology.
