OpenCPU User APIs are designed for accessing to hardware resources, radio communications resources,
user file system, or external devices. All APIs are introduced in Chapter 5.
OpenCPU RIL is an open source layer, which enables developers to simply call API to send AT and get
the response when API returns. Additionally, developers can easily add a new API to implement an AT
command. For more details, please refer to document Quectel_OpenCPU_RIL_Application_Note.
In OpenCPU RIL, all URC messages of module have already been reinterpreted and the result is
informed to App by system message. App will receive the message MSG_ID_URC_INDICATION when
an URC arrives.

4 System Configuration
In the \SDK\custom\config directory, developers can reconfigure the application according to their
requirements for heap memory size, tasks addition and task stack size configuration, as well as GPIO
initialization status. All config files for developers are named with prefix “custom_”.
Table 3: System Config File List
4.1. Configuration for Tasks
OpenCPU supports multitask processing. Developers only need to simply follow suit to add a record in
custom_task_cfg.h file to define a new task. OpenCPU supports one main task, and maximum TEN
subtasks.
If there are file operations in task, the stack size must be set to at least 5KB.
Developers should avoid calling these functions: Ql_Sleep(), Ql_OS_TakeSemaphore() and
Ql_OS_TakeMutex(). These functions will block the task, thus will make the task cannot fetch message
from the message queue. If the message queue is filled up, the system will automatically reboot
unexpectedly.
Config File
Description
custom_feature_def.h
OpenCPU features enabled. Now only includes RIL. Developers generally
do not need to change this file.
custom_gpio_cfg.h
Configurations for GPIO initialization status
custom_heap_cfg.h
Definition of heap memory size
custom_task_cfg.h
Multitask configuration
custom_sys_cfg.c
Other system configurations, including power key, specified GPIO pin for
external watchdog, and setting working mode of debug port.

4.2. Configuration for GPIO
In OpenCPU, there are two ways to initialize GPIOs. One is to configure GPIO list initialization in
custom_gpio_cfg.h; the other way is to call GPIO related APIs (Please refer to Chapter 5.7.2) to initialize

4.3.2. GPIO for External Watchdog
When an external watchdog is adopted to monitor the APP, the module has to feed the watchdog in the
whole period of the module‟s power-on, including the processess of startup, App activation and upgrade.
Table 5: Participants for Feeding External Watchdog
Therefore, developers just need to specify which GPIO is designed to feed the external watchdog.
static const ST_ExtWatchdogCfg wtdCfg = {
PINNAME_CTS, //Specify a pin or another GPIO to connect to the external watchdog.
PINNAME_END //Specify another pin for watchdog if needed.
};
4.3.3. Debug Port Working Mode Config
The serial debug port (UART2) may work as a common serial port (BASIC_MODE), or a special debug
port (ADVANCE_MODE) that can debug some issues during application.
Usually developers do not need to use ADVANCE_MODE when there are no requirements from support
engineer. If needed, please refer to document Quectel_Catcher_Operation_UGD for the usage of the
special debug port.
static const ST_DebugPortCfg debugPortCfg = {

5 API Functions
5.1. System API Functions
The header file ql_system.h declares system-related API functions. These functions are essential to any
customers‟ applications. Make sure the header file is included when using these functions.
OpenCPU provides interfaces that support multitasking, message, mutex, semaphore and event
mechanism functions. These interfaces are used for multitask programming. The example
example_multitask.c in OpenCPU SDK shows the proper usages of these API functions.
5.1.1. Usage
This section introduces some important operations and the API functions in system-level programming.
5.1.1.1. Receive Message
Developers can call Ql_OS_GetMessage to retrieve a message from the current task's message queue.
The message can be a system message, and also can be a customized message.
5.1.1.2. Send Message
Developers can call Ql_OS_SendMessage to send messages to other tasks. To send message,
developers have to define a message ID. In OpenCPU, user message ID must greater than 0x1000.
Step 1: Define message ID
#define MSG_ID_USER_START 0x1000
#define MSG_ID_MESSAGE1 (MSG_ID_USER_START + 1)
Step 2: Send message
Ql_OS_SendMessage(ql_subtask1, MSG_ID_MESSAGE1, 0, 0);
GSM/GPRS/GNSS Module Series
MC60-OpenCPU Series User Guide
MC60-OpenCPU_Series_User_Guide Confidential / Released 32 / 199
5.1.1.3. Mutex
A mutex object is a synchronization object whose state is set to signaled when it is not owned by any task,
and non-signaled when it is owned. A task can only own one mutex object at a time. For example, to
prevent two tasks from being written to shared memory at the same time, each task waits for ownership of
a mutex object before the code that accesses the memory is executed. After writing to the shared memory,
the task releases the mutex object.
Step 1: Create a mutex. Developers can call Ql_OS_CreateMutex to create a mutex.
Step 2: Get the specified mutex. If developers want to use mutex mechanism for programming, they can
call Ql_OS_TakeMute to get the specified mutex ID.
Step 3: Give the specified mutex. Developers can call Ql_OS_GiveMutex to release the specified mutex.
5.1.1.4. Semaphore
A semaphore object is a synchronization object that maintains a count between zero and a specified
maximum value. The count is decremented each time a task completes waiting for the semaphore object
and is incremented each time a task releases the semaphore. When the count reaches zero, no more
tasks can successfully wait for the semaphore object state to be signaled. The state of a semaphore is set
to signaled when its count is greater than zero and non-signaled when its count is zero.
Step 1: Create a semaphore. Developers can call Ql_OS_CreateSemaphore to create a semaphore.
Step 2: Get the specified emaphore. If developers want to use semaphore mechanism for programming,
they can call Ql_OSTakeSemaphore to get the specified semaphore ID.
Step 3: Give the specified semaphore. Developers can call Ql_OS_GiveSemaphore to release the
specified semaphore.
5.1.1.5. Event
An event object is a synchronization object, which is useful in sending a signal to a thread indicating that a
particular event has occurred. A task uses Ql_OS_CreateEvent function to create an event object, whose
state can be explicitly set to signaled by use of the Ql_OS_SetEvent function.
5.1.1.6. Backup Critical Data
OpenCPU has designed 13 blocks of system storage space to backup critical user data. Among the
storage blocks, blocks 1~8 can store 50 bytes data for each block, blocks 9~12 can store 100 bytes data
for each block, and block 13 can store 500 bytes data.
Developers may call Ql_SecureData_Store to backup data, and call Ql_Userdata_Read() to read back
data from backup space.

5.2. Time APIs
OpenCPU provides time-related APIs including setting local time, getting local time, converting the
calendar time into seconds or converting seconds into the calendar time, etc.
5.2.1. Usage
Calendar time is measured from a standard point in time to the current time elapsed seconds, generally
set at 00:00:00 on January 1st, 1970 as a standard point in time.
5.2.2. API Functions
The time struct is defined as follows:
typedef struct {
s32 year; //Range: 2000~2127
s32 month;
s32 day;
s32 hour; //In 24-hour time system
s32 minute;
s32 second;
s32 timezone; //Range: -12~12
}ST_Time;
The field “timezone” defines the time zone. A negative number indicates the Western Time zone, and a
positive number indicates the Eastern Time zone. For example: the time zone of Beijing is East Area 8,
then timezone=8; the time zone of Washington is West Zone 5, the timezone=-5.

Ql_Debug_Trace("<--%d/%d/%d %d:%d:%d %d -->\r\n",tm->year, tm->month, tm->day, tm->hour, tm
->minute, tm->second, tm->timezone);
5.3. Timer APIs
OpenCPU provides two kinds of timers. One is “Common Timer”, and the other is “Fast Timer”. OpenCPU
system allows maximum 10 Common Timers running at the same time in a task. The system provides
only one Fast Timer for application. The accuracy of the Fast Timer is relatively higher than a common
timer.
5.3.1. Usage
Developer uses Ql_Timer_Register() to create a common timer, and register the interrupt handler. And a
timer ID, which is an unsigned integer, must be specified. Ql_Timer_Start() can start the created timer,
and Ql_Timer_Stop() can stop the running timer.

The type of storage is divided into two kinds. One is the UFS in the flash, and the other is RAM file system.
The RAM file does not support directory structure. Developers can select the storage location according
to their own needs. When they want to create/open a file or directory, they must use a relative path. For
example, if they want to create a file in the root of the UFS, they can set the file as filename.ext for
instance.
- The Ql_FS_GetTotalSpace function is used to obtain the amount of total space on flash or SD card.
- The Ql_FS_GetFreeSpace function is used to obtain the amount of free space on flash or SD card.
- The Ql_FS_GetSize function is used to get the size of the specified file, and the size is in bytes.
- The Ql_FS_Open function is used to create or open a file. Developers must define the file's opening
and access modes. If developers want to know the usage of this function, please refer to the detailed
descriptions of it.
- The Ql_FS_Read and Ql_FS_Write functions are used to read and write a file. Developers must
ensure that the file has been opened.
- The Ql_FS_Seek and Ql_FS_GetFilePosition functions are used to set and get the position of the file
pointer. Developers must ensure that the file has been opened.
- The Ql_FS_Truncate function is used to truncate the specified file to zero length.
- The Ql_FS_Delete and Ql_FS_Check functions are used to delete and check a file.
- The Ql_FS_CreateDir, Ql_FS_DeleteDir and Ql_FS_CheckDir functions are used to create, delete
and check a specified directory.
- The Ql_FS_FindFirst, Ql_FS_FindNext and Ql_FS_XDelete functions are used to traverse all files
and directories in the specified directory. The three functions are usually used together.
- The Ql_FS_XDelete function is multi-functional. It can be used to delete a specified file or an empty
directory. Developers can also delete all files and directories in the specified directory by recursive
way.
- The Ql_FS_XMove function is used to move or copy a file or folder.
- The Ql_FS_Format function is used to format the UFS.
1. The RAM file does not support directory structure.
2. This stack size of the task, in which file operations will be executed, cannot be less than 5KB.

5.7. Hardware Interface APIs
5.7.1. UART
5.7.1.1. UART Overview
In OpenCPU, UART ports include physical UART ports and virtual UART ports. The physical UART ports
can be connected to external devices, and the virtual UART ports are used to communicate between
application and the bottom operating system.
One of the physical UART ports has hardware handshaking function, and others have three-wire
interfaces.
OpenCPU provides two virtual UART ports that are used for communication between App and Core.
GSM/GPRS/GNSS Module Series
MC60-OpenCPU Series User Guide
MC60-OpenCPU_Series_User_Guide Confidential / Released 76 / 199
These virtual ports are designed according to the features of physical serial interface. They have their RI
and DCD information. The level of DCD can be used to indicate the virtual port is in data mode or AT
command mode.
The working chart for UARTs is shown below:
Figure 3: The Working Chart of UART
5.7.1.2. UART Usage
For physical UART or virtual UART initialization and usage, developers can accomplish by following
simple steps.
Step 1: Call Ql_UART_Register to register the UART‟s callback function.
Step 2: Call Ql_UART_Open to open the special UART port.
Step 3: Call Ql_UART_Write to write data to the specified UART port. When the number of bytes actually
sent is less than that to be sent, application should stop sending data, and application will
receive an event EVENT_UART_READY_TO_WRITE later in callback function. After receiving
this event, application can continue to send data, and the previously unsent data should be
resent.
Step 4: Deal with the UART‟s notification in the callback function. If the notification type is
EVENT_UART_READY_TO_READ, developers should read out all data in the UART RX buffer.
Otherwise, there will not be such notification to be reported to application when new data comes

5.7.3. EINT
5.7.3.1. EINT Overview
OpenCPU module has three external interrupt pins, please refer to Chapter 5.7.2.2 for details. The
interrupt trigger mode just support level-triggered mode. The software debounce for external interrupt
sources is used to minimize the possibility of false activations. External interrupt has higher priority, so
frequent interrupt is not allowed. It is strongly recommended that the interrupt frequency is not more than
2, and too frequent interrupt will cause other tasks cannot be scheduled, which probably leads to
unexpected exception.
The interrupt response time is 50ms by default, and can be re-programmed to a greater value in
OpenCPU. However, it is strongly recommended that the interrupt frequency cannot be more than 3Hz so
as to ensure stable working of the module.
5.7.3.2. EINT Usage
The following steps show how to use the external interrupt function:
Step 1: Register an external interrupt function. Developers must choose one external interrupt pin and
use Ql_EINT_Register (or Ql_EINT_RegisterFast) to register an interrupt handler function.
Step 2: Initialize the interrupt configurations. Call Ql_EINT_Init function to configure the software
debounce time and set the level-triggered interrupt mode.
Step 3: Interrupt handle. The interrupt callback function will be called if the level has changed.
Developers can process something in the handler.
Step 4: Mask the interrupt. When developers do not want external interrupt. they can use
NOTE
GSM/GPRS/GNSS Module Series
MC60-OpenCPU Series User Guide
MC60-OpenCPU_Series_User_Guide Confidential / Released 94 / 199
Ql_EINT_Mask function to disable the external interrupt, and call the Ql_EINT_Unmask function
to enable the external interrupt.
Step 5: Release the specified EINT pin. Call Ql_EINT_Uninit function to release the specified EINT pin,
and the pin can be used for other purposes after it is released. This step is optional.

5.9. Socket APIs
5.9.1. Overview
Socket program implements the TCP and UDP protocols. In OpenCPU, developers use the API functions
to program TCP/UDP instead of using AT commands. Each PDP context supports at most 6 client socket
connections and 5 server socket connections.
The API functions in this section are declared in ql_socket.h.
5.9.2. Usage
5.9.2.1. TCP Client Socket Usage
The following steps tell how to work with TCP client socket:
Step 1: Register socket related callback functions. Call function Ql_SOC_Register to register the socket
related callback functions.
Step 2: Create a socket. Call function Ql_SOC_Create to create a socket. The “contextId” argument
should be the same as the one that Ql_GPRS_Register uses, and the “socketType” should be
set as “SOCK_TCP”.
Step 3: Connet to socket. Call Ql_SOC_Connect to request a socket connection. The
Callback_Socket_Connect function will be invoked no matter the connection is successful or not.
Step 4: Send data to socket. Call function Ql_SOC_Send to send data to socket. After the data is sent
out, developers can call Ql_SOC_GetAckNumber function to check whether the data is received
by the server. If Ql_SOC_Send retruns SOC_WOULDBLOCK, the application must wait for
Callback_Socket_Write function to send data again.
Step 5: Receive data from socket. When there is data coming from the socket, the callback_socket_read
function will be invoked to inform App. When received the notificatioin, application may call
Ql_SocketRecv to receive the data. Application must read out all the data. Otherwise, the
callback function will not be invoked when new data comes.
Step 6: Close the socket. Application can call function Ql_SOC_Close to close the socket. When
GSM/GPRS/GNSS Module Series
MC60-OpenCPU Series User Guide
MC60-OpenCPU_Series_User_Guide Confidential / Released 126 / 199
application receives the notification that the server side has closed the socket, application has to
call Ql_SOC_Close to close the socket from the client side.
5.9.2.2. TCP Server Socket Usage
The following steps tell how to work with the TCP Server:
Step 1: Register the socket related callback functions. Call function Ql_SOC_Register to register the
socket related callback functions.
Step 2: Create a socket. Call function Ql_SOC_Create to create a socket.
Step 3: Bind. Call function Ql_SOC_Bind to associate a local address with a socket.
Step 4: Listen. Call function Ql_SOC_Listen to start to listen to the connection request from listening
port.
Step 5: Accept connection request. When a connection request comes, Callback_Socket_Accept will be
invoked to inform App. Application can call function Ql_SOC_Accept to accept the connection
request.
Step 6: Send data to socket. Call function Ql_SOC_Send to send data to socket. After the data is sent out,
developers can call Ql_SOC_GetAckNumber function to check whether the data is received by
the client. When this function retruns SOC_WOULDBLOCK, the application has to wait till
Callback_Socket_Write is invoked, and then application can continue to send data.
Step 7: Receive data from socket. When data comes from the socket, the Callback_Socket_Read will be
invoked to inform application, and application can call Ql_SocketRecv to receive the data.
Application must read out all the data. Otherwise, the callback function will not be invoked when
new data comes.
Step 8: Close socket. Application can call function Ql_SOC_Close to close the socket. When application
receives the notification the client side has closed the socket, it has to call Ql_SOC_Close to
close the socket from the server side.
5.9.2.3. UDP Service Socket Usage
The following steps tell how to work with UDP Server:
Step 1: Register the socket related callback functions. Call function Ql_SOC_Register to register the
socket related callback functions.
Step 2: Create a socket. Call function Ql_SOC_Create to create a socket. The „contextId‟ argument
should be the same as the one that Ql_GPRS_Register uses, and the „socketType‟ should be
set as ‟SOCK_UDP‟.
Step 3: Bind. Call function Ql_SOC_Bind to associate a local address with a socket.
Step 4: Send data to socket. Call function Ql_SOC_SendTo to send data. When this function retruns
SOC_WOULDBLOCK, the application has to wait till Callback_Socket_Write is invoked, and
then App can continue to send data.
Step 5: Receive data from socket. When data comes from the socket, the Callback_Socket_Read
function will be invoked to inform application and application can call Ql_SocketRecvFrom to

MC60-OpenCPU_Series_User_Guide Confidential / Released 127 / 199
receive the data. App must read out all the data. Otherwise, the callback function will not be
invoked when new data comes.
Step 6: Close socket. Call function Ql_SOC_Close to close the socket. App can call function
Ql_SOC_Close to close the socket.

5.9.3.8. Ql_SOC_Send
This function sends data to a host which has already connected previously. It is used for TCP socket only.
If developers call Ql_SOC_Send function to send many data to the socket buffer, this function will return
SOC_WOULDBLOCK. Then developers must stop sending data. After the socket buffer has enough
space, the Callback_Socket_Write function will be called, and developers can continue to send the data.
This function just sends data to the network, but whether the data is received by the server is unknown.
So developers may need to call Ql_SOC_GetAckNumber function to check whether the data has been
received by the server.
- Prototype
s32 Ql_SOC_Send(s32 socketId, u8* pData, s32 dataLen)
- Parameters
socketId:
[In] Socket ID that is returned when calling Ql_SOC_Create.
pData:
[In] Pointer to the data to be sent.
dataLen:
[In] Number of bytes to send.
- Return Value
If no error occurs, Ql_SOC_Send returns the total number of bytes sent, which can be less than the
number requested to be sent by the dataLen parameter. Otherwise, a value of Enum_SocError is
returned.
1. The application should call Ql_SOC_Send circularly to send data till all the data in pData are sent out.
If the number of bytes actually sent is less than the number requested to be sent in the dataLen
parameter, the application should keep sending out the left data.
2. If the Ql_SocketSend returns a negative number, but not SOC_WOULDBLOCK, which indicates
some error happened to the socket, the application has to close the socket by calling
Ql_SocketClose and reestablish a connection to the socket. If the return value is
SOC_WOULDBLOCK, embedded application should stop sending data, and wait for the
Ql_Callback_Socket_Write() to be invoked to continue to send data.

5.12. Debug APIs
The head file ql_trace.h must be included so that the debug functions can be called. All examples in
OpenCPU SDK show the proper usages of these APIs.
5.12.1. Usage
There are two working modes for UART2 (DEBUG port): BASIC_MODE and ADVANCE_MODE.
Developers can configure the working mode of UART2 by the “debugPortCfg” variable in the
custom_sys_cfg.c file.
static const ST_DebugPortCfg debugPortCfg = {
BASIC_MODE //Set the serial debug port (UART2) to a common serial port.
//ADVANCE_MODE //Set the serial debug port (UART2) to a special debug port.
};
Under basic mode, application debug messages will be outputted as text through UART2 port. The
UART2 port works as common serial port with RX, TX and GND. In this case, UART2 can be used as
common serial port for application.
Under ADVANCE_MODE, both application debug messages and system debug messages will be
outputted through UART2 port with special format. The “Catcher Tool” provided by Quectel can be used to
capture and analyze these messages. Usually developers do not need to use ADVANCE_MODE without
the requirements from support engineer. If needed, please refer to document
Quectel_Catcher_Operation_UGD for the usage of the special debug mode.
5.12.2. API Functions
5.12.2.1. Ql_Debug_Trace
This function formats and prints a series of characters and values through the debug serial port (UART2).
Its function is the same as that of standard “sprintf”.

Pointer to a null-terminated multibyte string that specifies how to interpret the data. The maximum
string length is 512 bytes. Format-control string. A format specification has the following form:
%type:
A character that determines whether the associated argument is interpreted as a character, a string, or a
number.
Table 7: Format Specification for String Print
- Return Value
Number of characters printed.
1. The string to be printed must not be larger than the maximum number of bytes allowed in buffer.
Otherwise, a buffer overrun can occur.
2. The maximum allowed number of characters to be outputted is 512.
3. To print a 64-bit integer, please first convert it to characters using Ql_sprintf().
5.13. RIL APIs
OpenCPU RIL related API functions respectively implement the corresponding AT command‟s function.
Developers can simply call APIs to send AT commands and get the response when APIs return.
Developers can refer to document Quectel_OpenCPU_RIL_Application_Note for OpenCPU RIL
mechanism.
