@brief FreeRTOS Cellular library
|
||||
|
||||
FreeRTOS Cellular Library use communication interface to communicate with cellular modules to provide cellular network connectivity.
|
||||
|
||||
<b>FreeRTOS Cellular Library</b>
|
||||
- <b>Repository structure</b><br>
|
||||
This library contains the following three components in three folders.
|
||||
| FreeRTOS Cellular Library folders | High Level Description |
|
||||
| :--------------------| :--------------------- |
|
||||
| source | Reusable common code that implements the standard AT commands defined by 3GPP TS v27.007. |
|
||||
| docs | Documentations. |
|
||||
| test | Unit test and cbmc. |
|
||||
| tools | tools for Coverity static analysis and CMock. |
|
||||
|
||||
- <b>Supported cellular modules</b><br>
|
||||
Three cellular modules are supported in this library.
|
||||
| Cellular module |
|
||||
| :--------------------|
|
||||
| [Quectel BG96](https://github.com/FreeRTOS/FreeRTOS-Cellular-Interface-Reference-Quectel-BG96) |
|
||||
| [Sierra HL7802](https://github.com/FreeRTOS/FreeRTOS-Cellular-Interface-Reference-Sierra-Wireless-HL7802) |
|
||||
| [Ublox SARA R4 series](https://github.com/FreeRTOS/FreeRTOS-Cellular-Interface-Reference-ublox-SARA-R4) |
|
||||
New cellular module can reference these module porting to be integrated into FreeRTOS Cellular Library.<br>
|
||||
Please reference [Porting module Guide](https://www.freertos.org/Documentation/api-ref/cellular/cellular_porting_module_guide.html) document for detail information about porting new cellular module.
|
||||
- <b>Currently Supported Features in FreeRTOS Cellular Library</b>
|
||||
- User of FreeRTOS Cellular Library is able to use Cat-M1 cellular technology to connect to network.
|
||||
- User of FreeRTOS Cellular Library is able to perform control plane operations like (initialize modem, register on a network etc.) in a vendor agnostic way.
|
||||
- User of FreeRTOS Cellular Library is able to send and receive data using TCP/IP in a vendor agnostic way given that TCP/IP stack is running on the cellular modem.
|
||||
- User of FreeRTOS Cellular Library is able to put the modem in different low power modes (PSM and eDRX) in a vendor agnostic way.
|
||||
- User of FreeRTOS Cellular Library is able to receive asynchronous notifications about various events like "disconnected", "signal strength changed" etc. to enable them to take appropriate action as desired.
|
||||
- User of FreeRTOS Cellular Library is able to use the existing application protocol clients (MQTT, HTTP) over cellular seamlessly. i.e. any existing user application using MQTT which works over WiFi/Ethernet shall work over Cellular given the underlying cellular technology permits that.<br>

|

|

FreeRTOS Cellular Library uses communication interface to communicate with cellular modules.<br>
|
||||
Users of FreeRTOS Cellular Library should create a instance of CellularCommInterface and pass it
|
||||
to Cellular_Init function as paremeters.

@section cellular_socket_api_desing Cellular Socket API Design
|
||||
|
||||
FreeRTOS Cellular Interface offloads the TCP/IP stacks to cellular module. The implementation
|
||||
of the socket APIs use module specific AT commands. Cellular socket APIs abstract the differences
|
||||
between different cellular module. The following are cellular socket APIs:
|
||||
- @function_name{Cellular_CreateSocket}
|
||||
- @function_name{Cellular_SocketSetSockOpt}
|
||||
- @function_name{Cellular_SocketSend}
|
||||
- @function_name{Cellular_SocketRecv}
|
||||
- @function_name{Cellular_SocketClose}
|
||||
- @function_name{Cellular_GetHostByName}
|
||||
- @function_name{Cellular_SocketRegisterDataReadyCallback}
|
||||
- @function_name{Cellular_SocketRegisterClosedCallback}
|
||||
- @function_name{Cellular_SocketRegisterSocketOpenCallback}
|
||||
|
||||
Cellular socket APIs and cellular modem events change cellular socket state.
|
||||
See the below graph for the socket state transitions:

@page cellular_config Configurations
|

@brief Configurations of the Cellular Library.
|
||||
|
||||
Some configuration settings are C pre-processor constants, and some are function-like macros for logging. They can be set with a `#define` in the config file (**cellular_config.h**) or by using a compiler option such as -D in gcc.

1. [Configuration Macros](@ref cellular_porting_config)
|
||||
2. [Cellular Communication Interface](@ref cellular_porting_comm_if)
|

@brief Settings that must be set as macros in the config header `cellular_config.h`, or passed in as compiler options.
|
||||
|
||||
@note If a custom configuration header `cellular_config.h` is not provided, then the @ref CELLULAR_DO_NOT_USE_CUSTOM_CONFIG macro must be defined.
|
||||
|
||||
@see [Configurations](@ref cellular_config)
|
||||
|

In addition, the following logging macros are used throughout the library:
|
||||
- @ref LogError
|

- @ref LogWarn
|
||||
- @ref LogInfo
|
||||
- @ref LogDebug

@brief Introduction to cellular module porting<br>
|

|
||||
Cellular common library provides APIS and URC handler implemented with 3GPP v27.007 AT commands.<br>
|
||||
These APIs and URC handler can be reused when porting cellular module. <br>
|
||||
Reference the following pages for detail information.
|

- @subpage cellular_common_APIs
|
||||
- @subpage cellular_common_URC_handlers
|
||||
|
||||
Porting cellular module with cellular common portable with the following steps.<br>
|
||||
-# <b>Create a folder in modules with the following files. </b>
|
||||
- modules/(module_name)/cellular_(module_name).c
|
||||
- modules/(module_name)/cellular_(module_name)_api.c
|
||||
- modules/(module_name)/cellular_(module_name)_urc_handler.c
|
||||
- modules/(module_name)/cellular_(module_name)_wrapper.c
|
||||
-# <b>Implement cellular module porting interface @ref cellular_common_portable.h in cellular_(module_name).c </b><br>
|
||||
Reference @subpage cellular_module for detail information.
|
||||
-# <b>Implement FreeRTOS Cellular Library API with cellular module specific AT commands in cellular_(module_name)_api.c </b><br>
|
||||
Reference @subpage cellular_module_api for detail information.
|
||||
-# <b>Implement URC handler to handle URC event and call the corresponding callback function in cellular_(module_name)_urc_handler.c </b><br>
|
||||
Reference @subpage cellular_module_urc_handler for detail information.
|
||||
-# <b>Create FreeRTOS Cellular Library APIs implemented with 3GPP TS v27.007 AT commands ( @ref cellular_common_api.h ) in cellular_(module_name)_wrapper.c</b><br>
|
||||
|
||||
<b>Cellular module porting examples</b><br>
|
||||
Three cellular module portings can be referenced.<br>
|
||||
It is recommended that you start by cloning the implementation of one of the existing modems,<br>
|
||||
then make modifications where your modem's vendor-specific (non-3GPP) AT commands are different. <br>
